ISLSCP II Atmospheric Carbon Dioxide Consumption by Continental Erosion

Published by ORNL_DAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 08:44 PM | Dataset Last Updated: June 23, 2026
The Continental Atmospheric CO2 Consumption data set represents gridded estimates for the riverine export of carbon and of sediments based on empirical models. All data exist for the overall continental area in a spatial resolution of 0.5 x 0.5 degree longitude/ latitude. The units are tC/km2/yr for all carbon species, and t/km2/yr for sediment fluxes. There are two data files (*.zip) with this data set which describe the following: dissolved organic carbon (DOC) export, particulate organic carbon (POC) export, bicarbonate export, export of bicarbonate being of atmospheric origin (also called atmospheric CO2 consumption by rock weathering), and sediment export.
