Cal/Val will begin with a focus on instrument measurements, brightness temperature and backscatter, and evolve to the geophysical products that include three different spatial resolutions of surface soil moisture (36, 9, and 3 km). The goal is to provide validated products by May, 2016. SMAP will utilize five methodologies in soil moisture cal/val; core validation sites, sparse networks of in situ sensors, inter-comparisons with products from other satellite programs, inter-comparison with model-based products, and field campaigns. By Fall of 2015 there will be several months of SMAP observations that will include the North America summer. The process of product cal/val will be described and recent validation results presented. |
