Appendix 2: GEOS–CHEM Horizontal Coordinates


The GEOS–CHEM model can be run at the following horizontal resolutions:

We are currently precluded by computational limitations from running a global simulation at 1° x 1° resolution. Nevertheless, we have the capability to perform GEOS–CHEM simulations for selected sub-regions of the globe at 1 x 1 resolution. At present, we have implemented two such nested-grid regions:

Yuxuan Wang has defined a nested-grid over China and SE Asia which extends from

Qinbin Li and Rynda Hudman have defined North American nested grid which extends from

These sub-regions cover approximately 10% of the entire globe, and is sufficient to allow us to perform detailed NOx-Ox-hydrocarbon chemistry simulations with our current computing hardware.

All 1° x 1° nested-grid simulations must use the GEOS–3 meteorology, because GEOS–1 and GEOS–STRAT meteorologies have a maximum horizontal resolution of 2° x 2.5°, and because the native resolution of GEOS–4 is not 1° x 1° but rather 1° x 1.25°.
