SMAPVEX08 Vegetation Water Content Map, Version 1
Data set id:
SV08VWC
DOI: 10.5067/93BW6041HHO2
This is the most recent version of these data.

Overview

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. In addition, samples from a range of vegetation types were used to compare VWC and NDWI to the satellite imagery.
