Interpretive Summary:

Technical Abstract: During the post-launch Cal/Val Phase of SMAP there are two objectives for each science product team: 1) calibrate, verify, and improve the performance of the science algorithms, and 2) validate accuracies of the current release of the science data products as specified in the L1 science requirements according to the Cal/Val timeline. This report provides analysis and assessment of the SMAP Level 2 Soil Moisture Passive (L2SMP) Version 8 and the L2SMP Enhanced (L2SMP_E) Version 5 data products (also known as the R18 data release in October, 2021). The L2SMP product is provided on a 36-km EASE2 grid and the L2SMP_E on a 9-km EASE2 grid. The SMAP Level 3 Soil Moisture Passive (L3SMP, L3SMP_E) products are simply a daily composite of the L2 half-orbit files. Hence, analysis and assessment of the L2SMP and L2SMP_E products can also be considered to cover the L3SMP and L3SMP_E products. The assessment period now covers the first six years of the SMAP mission from March 31, 2015 to March 31, 2021.
