Interpretive Summary:

Technical Abstract: The NASA Soil Moisture Active Passive (SMAP) mission has recently expanded its products to included two soil moisture products with enhanced spatial resolutions. The soil moisture passive enhanced product exploits the oversampling along a scan to post data on a 9-km grid, which is a significant improvement over the standard 36-km grid posting. Validation indicates that interpreting the posting as spatial resolution introduces minor uncertainty. This advancement satisfies the original requirement of the SMAP mission using only the radiometer. Another new soil moisture product is being introduced that combines the SMAP radiometer and Sentinal-1 data to provide soil moisture at much higher spatial resolution (1- to 3-km). This does sacrifice temporal frequency. This new product presents challenges to the current validation infrastructure and is currently under evaluation.
