SMAPVEX08 Vegetation Water Content Map V001
Listed in NASA Earthdata CMR
The Vegetation Water Content (VWC) map for the Soil Moisture Active Passive Validation Experiment 2008 (SMAPVEX08) was derived by calculating Normalized Difference Water Index (NDWI) from Satellite Pour l'Observation de la Terre-4 (SPOT-4) overpasses on 11 October 2008.
Description
In addition, samples from a range of vegetation types were used to compare VWC and NDWI to the satellite imagery.
