NAME: BPCH2ASCII PURPOSE: Translates data from GAMAP-readable binary punch file v. 2.0 format to a simple ASCII file format CATEGORY: File & I/O, BPCH Format CALLING SEQUENCE: BPCH2ASCII, INFILE, OUTFILE [ , Keywords ] INPUTS: INFILE -> Name of the binary punch file to read. If INFILE is not passed, the user will be prompted to supply a file name via a dialog box. OUTFILE -> Name of the ASCII file to be written. It is recommended to insert the tokens %DATE% and %TIME% into OUTFILE, since BPCH2ASCII will write a separate netCDF file for each time index in the *.bpch file. The tokens %DATE% and %TIME% will be overwritten with the current values of YYYYMMDD and HHMMSS. Default is "bpch2nc_output.%DATE%.%TIME%.ascii". KEYWORD PARAMETERS: DIAGN -> A diagnostic category name (e.g. "IJ-AVG-$") or array of names which will restrict the data block selection. If DIAGN is omitted, then all data blocks within INFILE will be saved in ASCII format to OUTFILE. /VERBOSE -> If set, then BPCH2ASCII will also echo the header lines for each data block to the screen. FORMAT -> String containing the numeric format for for the data values. Default is '(7(e13.6,1x))' OUTPUTS: None SUBROUTINES: External Subroutines Required: ============================================= CTM_GET_DATA TAU2YYMMDD (function) GETMODELANDGRIDINFO REPLACE_TOKEN (function) UNDEFINE REQUIREMENTS: References routines from both GAMAP and TOOLS packages. NOTES: (1) BPCH2ASCII assumes that all data blocks in the *.bpch file file adhere to same grid. This will be true for output files from the GEOS-CHEM model. (2) BPCH2ASCII will write a separate ASCII file corresponding to each time index in the *.bpch file. This prevents file sizes from getting large, especially if there is a lot of diagnostic output in the *.bpch file. (3) BPCH2NC will replace the %DATE% token with the current YYYYMMDD value, and will replace the %TIME% token with the current HHMMSS value. Therefore, it is recommended to insert these tokens into the string passed via OUTFILE. The tokens %DATE% and %TIME% tokens may be either in uppercase or lowercase. (4) The format of the ASCII file is: Data block #1 header line Data block #1 values (format specified by FORMAT keyword) Data block #2 header line Data block #2 values (format specified by FORMAT keyword) ... The header line will contain the units and size of each data block. (5) The data is written to the ASCII file in column-major order (i.e. the same way as in FORTRAN), so you can read the data into FORTRAN w/ the following code: READ( IUNIT, '(a)' ) HEADER READ( IUNIT, '(1p,7(e13.6,1x))' ) & ((DATA(I,J), I=1,IMX), J=1,JMX) where IMX and JMX are the dimensions of the data block. EXAMPLE: BPCH2ASCII, 'myfile.bpch', 'myfile.%DATE%.%TIME%.ascii' ; Read data from binary punch file 'myfile.bpch' ; and writes it to ASCII file 'myfile.bpch.ascii'.

NAME: BPCH2COARDS PURPOSE: Reads data from a binary punch file and saves it in a COARDS-compliant netCDF (network Common Data Format) file. NOTE: COARDS is a formatting standard for netCDF files which is widely used in both the atmospheric & climate communities. COARDS-compliant netCDF files can be read by GAMAP, GrADS and other plotting packages. See http://ferret.wrc.noaa.gov/noaa_coop/coop_cdf_profile.html for more information about the COARDS standard. CATEGORY: File & I/O, BPCH Format, Scientific Data Formats CALLING SEQUENCE: BPCH2COARDS, INFILE, OUTFILE [, Keywords ] INPUTS: INFILE -> Name of the binary punch file to read. If INFILE is not passed, the user will be prompted to supply a file name via a dialog box. OUTFILE -> Name of the netCDF file to be written. It is recommended to insert the tokens %DATE% (or %date%) into OUTFILE, since BPCH2COARDS will write a separate netCDF file for each unique YYYYMMDD value contained within the *.bpch file. If OUTFILE is not specified, BPCH2COARDS will use the default file name "coards.%DATE%.nc". KEYWORD PARAMETERS: DIAGN -> Array of diagnostic categories from the bpch file to save to netCDF format. If omitted, BPCH2COARDS will save all diagnostic categories. /VERBOSE -> If set, will print the name of each tracer as it is being written to the netCDF file. Useful for debugging purposes. /NC4 -> Write a netCDF4 file instead of netCDF3. Default is NetCDF3. NetCDF4 support requires IDL 8.0 or later. COMPRESS -> Integer 0-9 specifies amount of compression in netCDF4 files. Default is 2, with very little benefit for higher compression. /PCOORD -> Use mean pressure as the vertical coordinate rather sigma or eta /ALTCOORD -> Use mean altitude as the vertical coordinate rather than sigma or eta /TROPONLY -> Write only tropospheric layers /ONEFILE -> Write all data to one netCDF output file. Default is one file per calendar day. _EXTRA=e -> Picks up additional keywords for NCDF_SET OUTPUTS: None SUBROUTINES: External Subroutines Required: ============================================ CTM_GET_DATA TAU2YYMMDD (function) UNDEFINE REPLACE_TOKEN (function) STRREPL (function) GETMODELANDGRIDINFO REQUIREMENTS: (1) References routines from GAMAP and TOOLS packages. (2) You must use a version of IDL containing the NCDF routines. NOTES: (1) BPCH2COARDS assumes that each data block in the *.bpch file is either 2-D (lon-lat) or 3-D (lon-lat-alt). (2) BPCH2COARDS assumes that the number type of each data block in the *.bpch file is REAL*4 (a.k.a. FLOAT). (3) BPCH2COARDS assumes that all data blocks in the *.bpch file adhere to same horizontal grid. This will always be true for output files from the GEOS-CHEM model. (4) BPCH2COARDS will write a separate COARDS-compliant netCDF file corresponding to each unique YYYYMMDD date. This prevents the files from becoming too large to be read with IDL. (5) BPCH2COARDS will replace the %DATE% (or %date%) token with the current YYYYMMDD value. Therefore, it is recommended to insert this token into the string passed via OUTFILE. (6) BPCH2COARDS will write arrays containing the latitudes, longitudes to the netCDF file. For 3-D data blocks, the eta or sigma centers will also be written to the file. Time will be written as TAU values (i.e. hours since 00:00 GMT on 01-Jan-1985. (7) The netCDF library has apparently been updated in IDL 6.0+. The result is that variable names containing characters such as '$', '=', and ':' may now cause an error in NCDF_VARDEF. Therefore, we now pre-screen tracer names with function NCDF_VALID_NAME. EXAMPLE: BPCH2COARDS, 'myfile.bpch', 'myfile.%DATE%.nc' ; Will write the contents of "myfile.bpch" to one ; or more COARDS-compliant netCDF files adhering ; to the filename convention "myfile.YYYYMMDD.nc" MODIFICATION HISTORY: rjp & bmy, 17 Mar 2005: GAMAP VERSION 2.03 - Based on bpch2nc.pro bmy, 21 Jul 2005: GAMAP VERSION 2.04 - Bug fix: bmy, 13 Jul 2006: GAMAP VERSION 2.05 - Remove call to PTR_FREE bmy & phs, 13 Jul 2007: GAMAP VERSION 2.10 - Now count GCAP among the GEOS family for the purpose of converting the TAU date to a YYYY/MM/DD date. phs, 29 Oct 2009: GAMAP VERSION 2.14 - Can process files with 3D data on both centers and edges of the grid boxes. bmy, 19 Dec 2011: GAMAP VERSION 2.16 - Now handles multiple vertical dimensions in the bpch file properly. - Bug fix: now write vertical levels edges to the file. bmy, 27 Sep 2012: - Bug fix: Now handle data blocks that straddle the date line. bmy, 05 Nov 2013: GAMAP VERSION 2.17 - Change attributes for better COARDS compliance bmy, 12 Feb 2014: GAMAP VERSION 2.18 - Add more modifications for 4-D data blocks from bpch files created w/ GC_COMBINE_ND49 bmy, 03 Mar 2015: - Now define dims in order: time, lev, lon, lat, which is more COARDS compliant. cdholmes, 29 Mar 2017 - Add support for NetCDF4 and compression - Add support for pressure and altitude as vertical coordinate - ONEFILE puts all data into a single output file - TROPONLY limits the output to troposphere layers - Singleton "altXXX" dimensions are avoided

NAME: BPCH2GMI PURPOSE: Reads data from a binary punch file and saves it in netCDF (network Common Data Format) format. The data will be shifted so that the first longitude is 0 degrees (i.e. the prime meridian) in order to conform with the GMI (Global Model Initiative) model grid definition. CATEGORY: File & I/O, BPCH Format, Scientific Data Formats CALLING SEQUENCE: BPCH2GMI, INFILE, OUTFILE [, Keywords ] INPUTS: INFILE -> Name of the binary punch file to read. If INFILE is not passed, the user will be prompted to supply a file name via a dialog box. OUTFILE -> Name of the netCDF file to be written.

(6) BPCH2GMI will write arrays containing the latitudes, longitudes to the netCDF file. For 3-D data blocks, the sigma centers will also be written to the file. Date and time are stored as global attributes. (7) The netCDF library has apparently been updated in IDL 6.0+.

CATEGORY: File & I/O, BPCH Format, Scientific Data Formats CALLING SEQUENCE: BPCH2HDF, INFILE, OUTFILE [, Keywords ] INPUTS: INFILE -> Name of the binary punch file to read. If INFILE is not passed, the user will be prompted to supply a file name via a dialog box. OUTFILE -> Name of the HDF file to be written. It is recommended to insert the tokens %DATE% and %TIME% into OUTFILE, since BPCH2HDF will write a separate HDF file for each time index in the *.bpch file. The tokens %DATE% and %TIME% will be overwritten with the current values of YYYYMMDD and HHMMSS. Default is "bpch2hdf_output.%DATE%.%TIME%.hdf". KEYWORD PARAMETERS: DIAGN -> A diagnostic category name (e.g. "IJ-AVG-$") or array of names which will restrict the data block selection. If DIAGN is omitted, then all data blocks within INFILE will be saved in HDF format to OUTFILE. _EXTRA=e -> Picks up additional keywords for HDF_SETSD OUTPUTS: SUBROUTINES: External Subroutines Required: ========================================= CTM_GET_DATA TAU2YYMMDD (function) UNDEFINE REPLACE_TOKEN (function) HDF_SETSD GETMODELANDGRIDINFO REQUIREMENTS: (1) References routines from GAMAP and TOOLS packages.

(6) BPCH2NC will write arrays containing the latitudes, longitudes to the netCDF file. (7) For pure-sigma grids (e.g. GEOS-1, GEOS-STRAT, GEOS-3), BPCH2NC will write the following additional variables to the netCDF file: (1) SIGE : Sigma coordinate at level edges (2) SIGC : Sigma coordinate at level centers The pressure at the bottom edge of level L is given by: Pe(L) = Ptop + [ SIGE(L) * ( Psurface - Ptop ) ] and the pressure at the vertical center of level L is: Pc(L) = Ptop + [ SIGC(L) * ( Psurface - Ptop ) ] %%%%% NOTE: This is mostly obsolete, as most met fields %%%%% that are used to drive CTM's are now placed onto %%%%% hybrid grids. (8) For hybrid grids (e.g. GEOS-4, GEOS-5, MERRA), the following dditional variables will be written to the netCDF file: (1) ETAE : Eta coordinate on level edges (2) ETAC : Eta coordinate on level centers (3) Ap : Hybrid grid "A" parameter (4) Bp : Hybrid grid "B" parameter The pressure at the bottom edge of level L is given by: Pe(L) = Ap(L) + ( Bp(L) * Psurface ) and the pressure at the vertical center of level L is: Pc(L) = ( Pe(L) + Pe(L+1) ) * 0.5 The hybrid ETA coordinates (similar to sigma) at the level edges and centers are, correspondingly: ETAE(L) = ( Pe(L) - Ptop ) / ( Psurface - Ptop ) ETAC(L) = ( Pc(L) - Ptop ) / ( Psurface - Ptop ) %%%%% NOTE: The ETAe and ETAc values are only approximate %%%%% and are computed with a surface pressure of 1013.25 %%%%% hPa. For your scientific analysis, you should compute %%%%% the pressures at level edges from Ap, Bp, and a %%%%% spatially-varying surface pressure field (e.g. saved %%%%% out from GEOS-Chem or another model). (7) The date and time of the data are stored in the netCDF file as global attributes. (8) The netCDF library has apparently been updated in IDL 6.0+.

NAME: BPCH2PCH PURPOSE: Translates data from GAMAP-readable binary punch file v. 2.0 format to the ancient ASCII-punch file standard. CATEGORY: File & I/O, BPCH Format CALLING SEQUENCE: BPCH2PCH, FILENAME [, OUTFILENAME [, Keywords ] ] INPUTS: FILENAME -> Name of the binary punch file from which to read data. FILENAME may be a file mask, and may contain wild card characters (e.g. ~/ctm.bpch.*). If FILENAME is omitted or contains a wild card character, the user will be prompted to pick a file via a dialog box. OUTFILENAME (optional) -> Name of the output ASCII punch file. Default is 'ASCIIfile.pch' KEYWORD PARAMETERS: DIAGN -> A diagnostic category name (e.g. "IJ-AVG-$") or array of names which will restrict the data block selection. If DIAGN is omitted, then all data blocks within INFILE will be saved in ASCII punch format to OUTFILE. /EXTRA_SPACE -> If set, will put an extra space between the numbers in the ASCII punch file. This might be necessary when using MATLAB or S-PLUS to read in the ASCII punch file. OUTPUTS: Writes data to ASCII punch file format SUBROUTINES: CTM_GET_DATA REQUIREMENTS: References routines from both GAMAP and TOOLS packages. NOTES: Some limitations: (1) Works only for global lon-lat diagnostics. (2) The top header line might be inaccurate (but nobody really reads that anyway, so forget it for now...) EXAMPLE: BPCH2PCH, '~/bmy/ctm.bpch', '~/bmy/ctm.pch' ; Reads data from binary punch file '~/bmy/ctm.bpch' ; and writes it to ASCII punch file '~/bmy/ctm.pch'.

NAME: BPCH_LINK PURPOSE: Copies data from several binary punch files into a single binary punch file. Also can trim data down to nested-grid resolution if necessary CATEGORY: File & I/O, BPCH Format CALLING SEQUENCE: BPCH_LINK, INFILES, OUTFILE [, Keywords ] INPUTS: INFILES -> A path name or file mask (with wildcards) which indicates the names of the individual files to be linked together in a single bpch file. OUTFILE -> Name of the bpch file that will contain data from the individual bpch files specified by INFILES. KEYWORD PARAMETERS: /CREATE_NESTED --> If set, then BPCH_LINK will trim data to the nested grid resolution as specified by the XRANGE and YRANGE keywords. XRANGE -> A 2-element vector containing the minimum and maximum box center longitudes which define the nested model grid. Default is [-180,180]. YRANGE -> A 2-element vector containing the minimum and maximum box center latitudes which define the nested model grid. Default is [-90,90]. OUTPUTS: None SUBROUTINES: External Subroutines Required: ============================== OPEN_FILE UNDEFINE CTM_DIAGINFO REQUIREMENTS: Requires routines from the GAMAP and TOOLS packages.

OUTPUTS: None SUBROUTINES: External Subroutines Required ================================ REQUIREMENTS: Requires other routines from the GAMAP package. NOTES: Assumes that each of the files passed via the FILES argument contains an identical sequence of diagnostic data blocks. This will normally be the case for GEOS-Chem simulations that have to be separated into several run stages for the queue system. Error checking is minimal, we will fix this later. This routine in intended for use with files that are created from individual stages of a long GEOS-Chem simulation. As such, we can usually assume that all files will have the same sequence of data blocks, and that all data blocks will be on the same grid. EXAMPLE: FILES = [ 'ctm.bpch.2011010100', 'ctm.bpch.2011011500' ] BPCH_MONTHLY_MEAN, FILES, OUTFILENAME = 'monthly_mean.bpch' ; Creates monthly-mean output from two GEOS-Chem bpch ; files that contain 15-day averaged data.

NAME: BPCH_SEP PURPOSE: Separates data from one binary punch file into another binary punch file by time (TAU0), tracer, or location indices. Useful for making smaller bpch files so that we don't run out of IDL memory when reading/processing them. CATEGORY: File & I/O, BPCH Format CALLING SEQUENCE:p BPCH_SEP, INFILE, OUTFILE [, Keywords ] INPUTS: INFILE -> A path name or file mask (with wildcards) which indicates the names of the individual files to be linked together in a single bpch file. OUTFILE -> Name of the bpch file that will contain data from the individual bpch files specified by INFILES. KEYWORD PARAMETERS: DIAGN -> Array of diagnostic categories for which to save out to OUTFILE Default is to save all diagnostic categories to OUTFILE. TAU0 -> Time index (hours from 1 Jan 1985) denoting the data blocks to be saved from INFILE to OUTFILE. You can use NYMD2TAU to compute this from a YYYYMMDD date. TRACER -> Tracer number(s) for which to save to OUTFILE. Default is to save all tracers. II, JJ, LL -> Longitude, latitude, altitude index arrays used to cut down the data block to less than global size. Use IDL notation, meaning first element is 0. GLOBALCOORDS -> When the data entries in the bpch file contain only part of the global CTM grid (e.g. ND48, ND49, ND50, ND51) this indicates that II, JJ, LL indices should be interpreted as global CTM indices, rather than relative to the regional subset grid. EXCLUDE -> Reverses the selection criteria, so that the designated DIAGN, TAU0, and TRACER are EXCLUDED from the output file. Everything else is included. In order to be excluded, a datablock must match all specified keywords: DIAGN, TAU0, and TRACER. OUTPUTS: None SUBROUTINES: External Subroutines Required: =============================================== CTM_DIAGINFO LITTLE_ENDIAN (function) OPEN_FILE UNDEFINE REQUIREMENTS: None NOTES: (1) Assumes that II, JJ, LL contain consecutive indices in longitude, latitude, and altitude, respectively. (2) Also assumes that II, JJ, LL are in IDL notation (i.e. starting from zero). This is so that you can pass the output from the WHERE command to BPCH_SEP. EXAMPLES: (1) BPCH_SEP, 'ctm.bpch.big', 'ctm.bpch.small', tau0=140256D ; Pulls out data blocks for TAU0=140256 (1/1/2001) from ; "ctm.bpch.big" and saves them in "ctm.bpch.small" (2) INTYPE = CTM_TYPE( 'GEOS4', RES=4 ) INGRID = CTM_GRID( INTYPE ) INDX = WHERE( INGRID.XMID ge -60 AND INGRID.XMID le 60 ) INDY = WHERE( INGRID.YMID ge 0 AND INGRID.YMID le 60 ) BPCH_SEP, 'ctm.bpch.big', 'ctm.bpch.small', II=INDX, JJ=INDY ; Pulls out all data blocks for the geographical area ; from 60W - 60E longitude and 0-60N latitude.

NAME: MAKE_MULTI_NC PURPOSE: Convert bpch files (matching a mask) to netCDF format. The routine can work recursively : files in subdirectories are also searched for. This is a convenient generic wrapper for GAMAP routine Bpch2coards.pro, to work on several files and directories at once. When working recursively, the directory tree in the input directory is recreated as needed in the output directory. CATEGORY: File & I/O, BPCH Format, Scientific Data Formats CALLING SEQUENCE: MAKE_MULTI_NC INPUTS: none KEYWORD PARAMETERS: MASK -> string, default is '*', that is all files INPUT_PARENT_DIR -> top directory of files to convert, if not specified, a dialog window pops up OUTPUT_PARENT_DIR -> top directory destination for netCDF files, if not specified, a dialog window pops up. RECURSION -> to search subdirectories. Default is 0 (OFF). Set to 1 to turn it on. TOKEN -> set if you want to replace 'bpch' with 'nc' in all part of the full name. Default is to have extension ".nc" added to file name only. OUTPUTS: None REQUIREMENTS: References routines from the GAMAP package. NOTES: To work recursively on the directories, I use FILE_SEARCH with 2 arguments. This is not possible with MFINDFILE, and works only with IDL 5.5 and above.
