Definition

  • [Source: NASA ASCENDS, https://www-air.larc.nasa.gov/missions/ascends/] The Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission objective is to make global atmospheric column carbon dioxide (CO2) measurements without a seasonal, latitudinal, or diurnal bias. The three science objectives are 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-degree 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.

ASCENDS will provide improved ability to predict/model long-term changes in the climate cycle based both on the understanding of the natural processes driving the variability of natural carbon sources and sinks, and on the transport of carbon through the atmosphere.
