Geostationary Coastal and Air Pollution Events (GEO-CAPE)

Status: Eliminated
Mission Category: Earth Systematic Missions, Decadal Survey 2007, Tier 2

The GEOstationary Coastal and Air Pollution Events (GEO-CAPE) mission was recommended by the NRC's Earth Science Decadal Survey to measure tropospheric trace gases and aerosols and coastal ocean phytoplankton, water quality and biogeochemistry from geostationary orbit, providing multiple daily observations within the field of view. Multiple observations per day are required to explore the physical, chemical, and dynamical processes that determine tropospheric composition and air quality over spatial scales ranging from urban to continental, and over temporal scales ranging from diurnal to seasonal. Likewise, high frequency satellite observations are critical to studying and quantifying biological, chemical, and physical processes within the coastal ocean and beyond.

These observations are to be achieved from a vantage point near 95°-100°W, to potentially view North and South America as well as the adjacent oceans. GEO-CAPE will join the global constellation of geostationary atmospheric chemistry and coastal ocean color sensors planned to be in orbit in the 2020 time frame.

The objectives of the Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission are to 1) identify human versus natural sources of aerosols and ozone precursors; 2) study the dynamics of coastal ecosystems, river plumes, and tidal fronts; 3) observe air pollution transport in North, Central, and South America; 4) predict the tracks of oil spills, fires, and releases from natural disasters; 5) detect and track waterbourne hazardous materials; 6) measure coastal health; and 7) facilitate forecasts of air quality.
