TL;DR: In this paper, a high-resolution active-passive soil moisture product was generated by using the C-band SAR data of the SMAP-Sentinel 1A/Sentinel-1B data set.
Journal ArticleDOI
Comparison of microwave remote sensing and land surface modeling for surface soil moisture climatology estimation
Jianzhi Dong,Wade T. Crow,Kenneth J. Tobin,Michael H. Cosh,David D. Bosch,Patrick J. Starks,Mark S. Seyfried,Chandra Holifield Collins +7 more
TL;DR: In this article, the authors evaluate surface soil moisture mean seasonal cycle (SMC) information acquired from different sources, including land surface models (LSMs), two C/X-band and two L-band remote sensing (RS) products.
Journal ArticleDOI

TL;DR: The NASA Soil Moisture Active Passive (SMAP) mission was launched on January 31st, 2015 and was able to collect and process ~2.5 months of the SMAP high-resolution active-passive soil moisture data, which coincided with the Northern Hemisphere vegetation green-up and crop growth season as discussed by the authors.
