Carbon dioxide (CO2) is the primary greenhouse gas responsible for warming the planet. While the global distribution of carbon dioxide in the atmosphere is well known, tracking the emissions of CO2 to their sources is a challenge, especially over large urban areas. One approach uses the NASA instrument Measurement of Pollution in the Troposphere (MOPITT). Here scientists explore how carbon monoxide (CO) emission measurements from MOPITT can complement existing satellite CO2 measurements in megacities delineated by SEDAC’s Gridded Population of the World, to provide improved spatial and temporal understanding of CO2 emissions.
The SEDAC data set Low-elevation Coastal Zone (LECZ) is the basis for a set of national-level indicators of the total area and population in the LECZ circa 2000.
