Status: Future, Pre-Formulation
Mission Category: Earth Systematic Missions, Decadal Survey, Tier 2

The Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission will make global atmospheric column carbon dioxide (CO2) measurements without a seasonal, latitudinal, or diurnal bias. The mission will also measure also measure ambient air pressure and temperature. The measurements made by ASCENDS will allow the mission to: 1) quantify global spatial distributions of atmospheric CO2 on scales of weather models in the 2010-2020 era; 2) quantify the current global spatial distribution of terrestrial and oceanic sources and sinks of CO2 on 1 x 1 grids at weekly resolution; and 3) provide a scientific basis for future projections of CO2 sources and sinks through data-driven enhancements of Earth system process modeling.
