SMAPVEX12 Vegetation Water Content Map V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Catalog Last Checked: July 14, 2026 at 11:24 PM | Dataset Last Updated: July 17, 2025
The daily Vegetation Water Content (VWC) maps for the Soil Moisture Active Passive Validation Experiment 2012 (SMAPVEX12) were derived by calculating Normalized Difference Vegetation Index (NDVI) from SPOT and RapidEye satellite overpasses and then interpolating it for each day of the campaign. In addition, samples from a range of vegetation types were used to compare ground-based measurements to the satellite-based estimates.
