An Improved Canopy Integration Scheme for a Land Surface Model with Prognostic Canopy Structure
Publisher: American Meteorological Society
Abstract: A new logical framework relating the structural and functional characteristics of a vegetation canopy is presented, based on the hypothesis that the ratio of leaf area to leaf mass (specific leaf area) varies linearly with ...
Evaluation of the New CNDV Option of the Community Land Model: Effects of Dynamic Vegetation and Interactive Nitrogen on CLM4 Means and Variability
Publisher: American Meteorological Society
Abstract: he Community Land Model, version 4 (CLM4) includes the option to run the prognostic carbon?nitrogen (CN) model with dynamic vegetation (CNDV). CNDV, which simulates unmanaged vegetation, modifies the CN framework to implement ...
Parameterization and Sensitivity Analysis of the BIOME–BGC Terrestrial Ecosystem Model: Net Primary Production Controls
Publisher: American Meteorological Society
Abstract: Ecosystem simulation models use descriptive input parameters to establish the physiology, biochemistry, structure, and allocation patterns of vegetation functional types, or biomes. For single-stand simulations it is ...
Assessment of Reanalysis Daily Extreme Temperatures with China’s Homogenized Historical Dataset during 1979–2001 Using Probability Density Functions
Publisher: American Meteorological Society
Abstract: Using a recently homogenized observational daily maximum (TMAX) and minimum temperature (TMIN) dataset for China, the extreme temperatures from the 40-yr ECMWF Re-Analysis (ERA-40), the Japanese 25-year Reanalysis (JRA-25), ...
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 ...
Remote Sensing Evaluation of CLM4 GPP for the Period 2000–09
Publisher: American Meteorological Society
Abstract: emote sensing can provide long-term and large-scale products helpful for ecosystem model evaluation. The authors compare monthly gross primary production (GPP) simulated by the Community Land Model, version 4 (CLM4) at a ...
Interactive Crop Management in the Community Earth System Model (CESM1): Seasonal Influences on Land–Atmosphere Fluxes
Publisher: American Meteorological Society
Abstract: he Community Earth System Model, version 1 (CESM1) is evaluated with two coupled atmosphere?land simulations. The CTRL (control) simulation represents crops as unmanaged grasses, while CROP represents a crop managed ...
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 ...
Simulating the Biogeochemical and Biogeophysical Impacts of Transient Land Cover Change and Wood Harvest in the Community Climate System Model (CCSM4) from 1850 to 2100
Publisher: American Meteorological Society
Abstract: o assess the climate impacts of historical and projected land cover change in the Community Climate System Model, version 4 (CCSM4), new time series of transient Community Land Model, version 4 (CLM4) plant functional type ...
Greenhouse Gas Policy Influences Climate via Direct Effects of Land-Use Change
Publisher: American Meteorological Society
Abstract: roposed climate mitigation measures do not account for direct biophysical climate impacts of land-use change (LUC), nor do the stabilization targets modeled for phase 5 of the Coupled Model Intercomparison Project (CMIP5) ...
