Assessment and Enhancement of MERRA Land Surface Hydrology Estimates
Rolf H. Reichle,Randal D. Koster,Gabrielle De Lannoy,Barton A. Forman,Qing Liu,Sarith Mahanama,A. Toure +6 more
TL;DR: In this paper, the authors introduced a supplemental and improved set of land surface hydrological fields (MERRA-Land) generated by rerunning a revised version of the land component of the MERRA system.
Journal ArticleDOI
Assimilation of passive and active microwave soil moisture retrievals
Clara S. Draper,Clara S. Draper,Rolf H. Reichle,G. De Lannoy,G. De Lannoy,G. De Lannoy,Qing Liu,Qing Liu +7 more
TL;DR: In this article, the authors compared the impact of assimilating ASCAT and AMSR-E soil moisture data, both separately and together, according to land cover type, by comparison to in situ soil moisture observations.
Journal ArticleDOI

The Contributions of Precipitation and Soil Moisture Observations to the Skill of Soil Moisture Estimates in a Land Data Assimilation System
Qing Liu,Qing Liu,Rolf H. Reichle,Rajat Bindlish,Michael H. Cosh,Wade T. Crow,Richard de Jeu,Gabrielle De Lannoy,Gabrielle De Lannoy,Gabrielle De Lannoy,George J. Huffman,Thomas J. Jackson +11 more
TL;DR: In this paper, the contributions of precipitation and soil moisture observations to soil moisture skill in a land data assimilation system are assessed using in situ observations in the continental United States at 37 single-profile sites within the Soil Climate Analysis Network (SCAN) for which skillful AMSR-E retrievals are available and at 4 USDA Agricultural Research Service (CalVal) watersheds with high-quality distributed sensor networks that measure soil moisture at the scale of land model and satel...
Journal ArticleDOI
An updated treatment of soil texture and associated hydraulic properties in a global land modeling system
Gabrielle De Lannoy,Gabrielle De Lannoy,Randal D. Koster,Rolf H. Reichle,Sarith Mahanama,Qing Liu +5 more
TL;DR: In this paper, the authors describe the composition of a new soil texture data set and its implementation into a specific land surface modeling system, namely, the Catchment land surface model (LSM) of the NASA Goddard Earth Observing System version 5 (GEOS-5) modeling and assimilation framework.
