RISForward-Looking Assimilation of MODIS-Derived Snow-Covered Area into a Land Surface Model
Publisher: American Meteorological Society
Abstract: Snow cover over land has a significant impact on the surface radiation budget, turbulent energy fluxes to the atmosphere, and local hydrological fluxes. For this reason, inaccuracies in the representation of snow-covered ...
Simulating the Effects of Irrigation over the United States in a Land Surface Model Based on Satellite-Derived Agricultural Data
Publisher: American Meteorological Society
Abstract: A novel method is introduced for integrating satellite-derived irrigation data and high-resolution crop-type information into a land surface model (LSM). The objective is to improve the simulation of land surface states ...
Assimilation of GRACE Terrestrial Water Storage Data into a Land Surface Model: Results for the Mississippi River Basin
Publisher: American Meteorological Society
Abstract: Assimilation of data from the Gravity Recovery and Climate Experiment (GRACE) system of satellites yielded improved simulation of water storage and fluxes in the Mississippi River basin, as evaluated against independent ...
Impact of Irrigation Methods on Land Surface Model Spinup and Initialization of WRF Forecasts
Publisher: American Meteorological Society
Abstract: n the United States, irrigation represents the largest consumptive use of freshwater and accounts for approximately one-third of total water usage. Irrigation impacts soil moisture and can ultimately influence clouds and ...
Estimating Snow Water Storage in North America Using CLM4, DART, and Snow Radiance Data Assimilation
Publisher: American Meteorological Society
Abstract: his paper addresses continental-scale snow estimates in North America using a recently developed snow radiance assimilation (RA) system. A series of RA experiments with the ensemble adjustment Kalman filter are conducted ...
Evaluation of the Snow Simulations from the Community Land Model, Version 4 (CLM4)
Publisher: American Meteorological Society
Abstract: his paper evaluates the simulation of snow by the Community Land Model, version 4 (CLM4), the land model component of the Community Earth System Model, version 1.0.4 (CESM1.0.4). CLM4 was run in an offline mode forced with ...
The Value of Remotely Sensed Information: The Case of a GRACE-Enhanced Drought Severity Index
Publisher: American Meteorological Society
Abstract: AbstractA decision framework is developed for quantifying the economic value of information (VOI) from the Gravity Recovery and Climate Experiment (GRACE) satellite mission for drought monitoring, with a focus on the ...
