Updating a Land Surface Model with MODIS-Derived Snow Cover
Publisher: American Meteorological Society
Abstract: A simple scheme for updating snow-water storage in a land surface model using snow cover observations is presented. The scheme makes use of snow cover observations retrieved from the Moderate Resolution Imaging Spectroradiometer ...
Evaluation of 10 Methods for Initializing a Land Surface Model
Publisher: American Meteorological Society
Abstract: Improper initialization of numerical models can cause spurious trends in the output, inviting erroneous interpretations of the earth system processes that one wishes to study. In particular, soil moisture memory is ...
The Global Land Data Assimilation System
Publisher: American Meteorological Society
Abstract: A Global Land Data Assimilation System (GLDAS) has been developed. Its purpose is to ingest satellite- and ground-based observational data products, using advanced land surface modeling and data assimilation techniques, ...
The Observed State of the Water Cycle in the Early Twenty-First Century
Publisher: American Meteorological Society
Abstract: his study quantifies mean annual and monthly fluxes of Earth?s water cycle over continents and ocean basins during the first decade of the millennium. To the extent possible, the flux estimates are based on satellite ...
The Observed State of the Energy Budget in the Early Twenty-First Century
Publisher: American Meteorological Society
Abstract: ew objectively balanced observation-based reconstructions of global and continental energy budgets and their seasonal variability are presented that span the golden decade of Earth-observing satellites at the start of the ...
