Welcome to the homepage for NASA GSFC Code 614 and GMAO chemical constituent forecasts. Results are shown for forecasts run with the GEOS-5 model. Assimilation of aerosol optical thickness based on MODIS is included. Please note that these forecasts are considered "experimental" and so should not be published.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 GEOS-5 General Circulation Model with its meteorological data assimilation system. On this page we present results for aerosols, CO (carbon monoxide), and CO2 (carbon dioxide). The aerosol package is based on GOCART [Chin et al., JGR, 2002; Colarco et al., JGR, 2010] and contains dust, seasalt, sulfate, black carbon, and organic carbon aerosols. Biomass burning sources of carbonaceous aerosols, CO, CO2, 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 and CO2 components. Arlindo da Silva is responsible for the biomass burning sources. Peter Colarco is responsible for the web page.
