The Soil Moisture Active Passive (SMAP) mission entered its one year calibration and validation (cal/val) phase in May, 2015. This began with a focus on instrument measurements, brightness temperature and backscatter, and has now evolved to the geophysical products that include three different spatial resolutions of Level 2/3 surface soil moisture (36, 9, and 3 km) and freeze-thaw state. The goal is to provide validated products by May, 2016. SMAP utilizes 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-comparisons with model-based products, and field campaigns. Each methodology has a role in the process. Examples of each methodology will be presented including recent field campaigns. The evaluation of the beta version will the explained and plans for the providing the validated products presented.
