RISDesign of Total Runoff Integrating Pathways (TRIP)—A Global River Channel Network
Publisher: American Meteorological Society
Abstract: As a first step toward designing a comprehensive model for validating land surface hydrology and river flow in Earth system models, a global river channel network has been prepared at 1° latitude ? 1° longitude resolution. ...
A GCM Simulation Study of the Influence of Saharan Evapotranspiration and Surface-Albedo Anomalies on July Circulation and Rainfall
Publisher: American Meteorological Society
Abstract: The GLA (Goddard Laboratory for Atmospheres) GCM (general circulation model) was employed to investigate the influence of surface albedo and evapotranspiration anomalies that could result from the hypothetical semiarid ...
Comparison of Ocean Surface Solar Irradiance in the GLA General Circulation Model and Satellite-based Calculations
Publisher: American Meteorological Society
Abstract: A global, 7-year satellite-based record of ocean surface solar irradiance (SSI) is used to assess the realism of ocean SSI simulated by the nine-layer Goddard Laboratory for Atmospheres (GLA) General Circulation Model ...
Refinements to SSiB with an Emphasis on Snow Physics: Evaluation and Validation Using GSWP and Valdai Data
Publisher: American Meteorological Society
Abstract: Refinements to the snow-physics scheme of the Simplified Simple Biosphere Model (SSiB) are described and evaluated. The upgrades include a partial redesign of the conceptual architecture of snowpack to better simulate the ...
Microphysics of Clouds with the Relaxed Arakawa–Schubert Scheme (McRAS). Part I: Design and Evaluation with GATE Phase III Data
Publisher: American Meteorological Society
Abstract: A prognostic cloud scheme named McRAS (Microphysics of Clouds with Relaxed Arakawa?Schubert Scheme) has been designed and developed with the aim of improving moist processes, microphysics of clouds, and cloud?radiation ...
Microphysics of Clouds with the Relaxed Arakawa–Schubert Scheme (McRAS). Part II: Implementation and Performance in GEOS II GCM
Publisher: American Meteorological Society
Abstract: A prognostic cloud scheme named the Microphysics of Clouds with the Relaxed Arakawa?Schubert Scheme (McRAS) and the Simple Biosphere Model have been implemented in a version of the Goddard Earth Observing System (GEOS) II ...
Simulation Errors Associated with the Neglect of Oceanic Salinity in an Atmospheric GCM
Publisher: American Meteorological Society
Abstract: In all the atmospheric general circulation models (GCMs) at the Goddard Laboratory for Atmospheres (GLA), the influence of oceanic salinity on the saturation vapor pressure of seawater is ignored. Since the relative humidity ...
Comparison of a Land Surface Model (SSiB) to Three Parameterizations of Evapotranspiration—A Study Based on ISLSCP Initiative I Data
Publisher: American Meteorological Society
Abstract: Four different methods of estimating land surface evapotranspiration are compared by forcing each scheme with near-surface atmospheric and soil- and vegetation-type forcing data available through International Satellite ...
Influence of Land Surface Roughness on Atmospheric Circulation and Precipitation: A Sensitivity Study with a General Circulation Model
Publisher: American Meteorological Society
Abstract: The influence of land surface roughness on the large scale atmospheric circulation and rainfall was examined by comparing three sets of simulations made with a general circulation model in which the land surface roughness ...
Influence of Local Land-Surface Processes on the Indian Monsoon: A Numerical Study
Publisher: American Meteorological Society
Abstract: Twelve July integrations were made with the GLAS (Goddard Laboratory for Atmospheres) GCM (General Circulation Model) to investigate the influence of changes in the land-surface fluxes over the Indian subcontinent on the ...
