Development and Applications of Atmospheric Chemistry Products from Operational Environmental Satellite Systems

摘要

The use of remotely sensed trace gas and aerosol data for environmental monitoring and forecasting has evolved tremendously in the last decade. NOAA/NESDIS has been active in developing near-real-time satellite products for environmental applications from its geostationary and polar-orbiting satellites for users such as the Environmental Protection Agency (EPA) and the NOAA/National Weather Service (NWS). Satellite derived aerosol optical depths, ozone, and PM2.5 (particulate matter with median particle size less than 2.5 microns) emissions in near real time are currently being used by the NWS in air quality forecast verification and in air quality modeling to improve forecasts. Plans are underway to expand the operational product development to trace gases such as NO{sub}2, H{sub}2CO, SO{sub}2, CO, CH{sub}4, CHO-CHO, and absorption/scattering optical depths with the launch of Initial Joint Polar-orbiting Operational Satellite System (IJPS) GOME-2 and IASI instruments in 2006. The launch of NPP, NPOESS, and GOES-R sensors (e.g., OMPS, CrIS, ABI, HES) in the next decade will strengthen and expand this early progress. We present examples of air quality and other applications of current operational satellite data and discuss potential applications with future satellite sensors.
