Project Overview 

The measurement of both Vegetation Water Content (VWC) and the spectral reflectance is for the purpose of comparing the vegetation optical depths, respectively, based on the fact that LAI can be retrieved using the optical reflectance. 

Till now, extensive data have been collected. Soil texture analysis has also been carried out for different locations and depths. The average soil texture is 18.3% clay, 13.7% sand, and 68% silt, indicating a silt loam soil.
