RISContrasts between Urban and Rural Climate in CCSM4 CMIP5 Climate Change Scenarios
Publisher: American Meteorological Society
Abstract: new parameterization of urban areas in the Community Climate System Model version 4 (CCSM4) allows for simulation of temperature in cities where most of the global population lives. CCSM4 Coupled Model Intercomparison ...
The Effects of Remotely Sensed Plant Functional Type and Leaf Area Index on Simulations of Boreal Forest Surface Fluxes by the NCAR Land Surface Model
Publisher: American Meteorological Society
Abstract: The land surface models used with atmospheric models typically characterize landscapes in terms of generalized biome types. However, the advent of high?spatial resolution satellite-derived data products such as land cover ...
Simulation of Global Land Surface Conditions from 1948 to 2004. Part I: Forcing Data and Evaluations
Publisher: American Meteorological Society
Abstract: Because of a lack of observations, historical simulations of land surface conditions using land surface models are needed for studying variability and changes in the continental water cycle and for providing initial ...
The Partitioning of Evapotranspiration into Transpiration, Soil Evaporation, and Canopy Evaporation in a GCM: Impacts on Land–Atmosphere Interaction
Publisher: American Meteorological Society
Abstract: Although the global partitioning of evapotranspiration (ET) into transpiration, soil evaporation, and canopy evaporation is not well known, most current land surface schemes and the few available observations indicate that ...
Treatment of Undercanopy Turbulence in Land Models
Publisher: American Meteorological Society
Abstract: In arid and semiarid regions most of the solar radiation penetrates through the canopy and reaches the ground, and hence the turbulent exchange coefficient under canopy Cs becomes important. The use of a constant Cs that ...
CCSM–CAM3 Climate Simulation Sensitivity to Changes in Horizontal Resolution
Publisher: American Meteorological Society
Abstract: The latest version of the Community Climate System Model (CCSM) Community Atmosphere Model version 3 (CAM3) has been released to allow for numerical integration at a variety of horizontal resolutions. One goal of the CAM3 ...
The Land Surface Climatology of the Community Land Model Coupled to the NCAR Community Climate Model
Publisher: American Meteorological Society
Abstract: The land surface parameterization used with the community climate model (CCM3) and the climate system model (CSM1), the National Center for Atmospheric Research land surface model (NCAR LSM1), has been modified as part of ...
The Community Land Model and Its Climate Statistics as a Component of the Community Climate System Model
Publisher: American Meteorological Society
Abstract: Several multidecadal simulations have been carried out with the new version of the Community Climate System Model (CCSM). This paper reports an analysis of the land component of these simulations. Global annual averages ...
The CCSM4 Land Simulation, 1850–2005: Assessment of Surface Climate and New Capabilities
Publisher: American Meteorological Society
Abstract: his paper reviews developments for the Community Land Model, version 4 (CLM4), examines the land surface climate simulation of the Community Climate System Model, version 4 (CCSM4) compared to CCSM3, and assesses new earth ...
Soil Moisture Memory in AGCM Simulations: Analysis of Global Land–Atmosphere Coupling Experiment (GLACE) Data
Publisher: American Meteorological Society
Abstract: Soil moisture memory is a key aspect of land?atmosphere interaction and has major implications for seasonal forecasting. Because of a severe lack of soil moisture observations on most continents, existing analyses of ...
