Dr. Lakhankar and CREST team participating in NASA’s Soil Moisture Active Passive Validation Experiment 2019 (SMAPVEX19) conducted at Worcester County Massachusetts and Duchess County, New York.  SMAPVEX19 builds upon a long history of NASA’s satellite validation experiments, which include satellite remote sensing, an airborne campaign, a temporary in situ network deployment and intensive observation periods with physical visitation and sampling.  NOAA-CREST L-band (1.45 GHz) dual polarization microwave radiometer deployed for measuring soil and canopy brightness temperature. These field campaigns have application in a broad range of scientific areas, focusing on technology development and demonstration, validating satellite-based geophysical products and providing educational experiences for students.
