TL;DR: The Level 2 Passive Soil Moisture Product (L2_SM_P) as discussed by the authors was developed by the National Aeronautics and Space Administration (NASA) soil moisture active passive (SMAP) satellite mission and is available from the Distributed Active Archive Center at the National Snow and Ice Data Center.
Journal ArticleDOI
Vegetation and surface roughness effects on AMSR-E land observations
Eni G. Njoku,Steven Chan +1 more
TL;DR: In this paper, a characterization of vegetation and soil roughness at the frequencies and spatial resolution of the EOS Aqua Advanced Microwave Scanning Radiometer (AMSR-E) is presented.
Journal ArticleDOI
Vegetation optical depth and scattering albedo retrieval using time series of dual-polarized L-band radiometer observations
Alexandra G. Konings,Maria Piles,Kathrina Rötzer,Kaighin A. McColl,Steven Chan,Dara Entekhabi +5 more
TL;DR: In this paper, a multi-temporal dual channel algorithm (MT-DCA) was proposed to estimate vegetation optical depth and soil moisture from time series of dual-polarized L-band radiometric observations along with time-invariant scattering albedo.

Journal ArticleDOI
Application of Triple Collocation in Ground-Based Validation of Soil Moisture Active/Passive (SMAP) Level 2 Data Products
Fan Chen,Wade T. Crow,Andreas Colliander,Michael H. Cosh,Thomas J. Jackson,Rajat Bindlish,Rolf H. Reichle,Steven Chan,David D. Bosch,Patrick J. Starks,David C. Goodrich,Mark S. Seyfried +11 more
TL;DR: Application of this TC strategy at five SMAP core validation sites suggests that unbiased estimates of correlation between the satellite product and the true footprint average can be obtained—even in cases where ground observations provide only one single reference point within the footprint.
