GEOS-5 Chemical and Aerosol Consituent Forecasts

Welcome to the homepage for NASA GSFC Code 613.3 and GMAO chemical constituent forecasts supporting GloPac. Results are shown for forecasts run with the GEOS-5 model. Please note that these forecasts are considered "experimental" and so should not be published. Please contact the web curator with any questions.

Notes:

Model runs are generated with the NASA finite-volume General Circulation Model with the GEOS-5 meteorological assimilation and physics packages. On this page we present results for aerosos and CO (carbon monoxide). The aerosol package is based on GOCART [Chin et al., JGR, 2002] and contains dust, seasalt, sulfate, black carbon, and organic carbon aerosols. Biomass burning sources of carbonaceous aerosols, CO, and SO2 are determined in near real-time (and propagated forward in time for forecasts) from MODIS imagery and land mapping. Peter Colarco and Arlindo da Silva are responsible for the aerosol component. Randy Kawa and Huisheng Bian are responsible for the CO component. Arlindo da Silva is responsible for the biomass burning sources. Peter Colarco is responsible for the web page.
