RISThe Effects of Observed Fractional Vegetation Cover on the Land Surface Climatology of the Community Land Model
Publisher: American Meteorological Society
Abstract: Accurate modeling of surface processes requires a specification of the amount of land covered by vegetation. The National Center for Atmospheric Research Community Land Model (CLM2) does not realistically represent sparsely ...
The Influence of Fire-Induced Surface Changes on the Diurnal Temperature Changes over the Hayman Fire Scar
Publisher: American Meteorological Society
Abstract: uring the 2010 Bio?Hydro?Atmosphere Interactions of Energy, Aerosols, Carbon, H2O, and Nitrogen (BEACHON) experiment in Colorado, nighttime temperatures over a site within the 2002 ?Hayman? fire scar were considerably ...
Revising the Ensemble-Based Kalman Filter Covariance for the Retrieval of Deep-Layer Soil Moisture
Publisher: American Meteorological Society
Abstract: Previous studies have demonstrated that soil moisture in the top layers (e.g., within the top 1-m depth) can be retrieved by assimilating near-surface soil moisture observations into a land surface model using ensemble-based ...
A Trial to Improve Surface Heat Exchange Simulation through Sensitivity Experiments over a Desert Steppe Site
Publisher: American Meteorological Society
Abstract: t is still a daunting challenge for land surface models (LSMs) to correctly represent surface heat exchange for water-limited desert steppe ecosystems. This study aims to improve the ability of the Noah LSM to simulate ...
Meteorological Impacts of Forest Mortality due to Insect Infestation in Colorado
Publisher: American Meteorological Society
Abstract: hysical characteristics of forests and other ecosystems control land?atmosphere exchanges of water and energy and partly dictate local and regional meteorology. Insect infestation and resulting forest dieback can alter ...
The Impact of Noah-MP Physical Parameterizations on Modeling Water Availability during Droughts in the Texas–Gulf Region
Publisher: American Meteorological Society
Evaluation of Land–Atmosphere Coupling Processes and Climatological Bias in the UFS Global Coupled Model

Assessing Impacts of Integrating MODIS Vegetation Data in the Weather Research and Forecasting (WRF) Model Coupled to Two Different Canopy-Resistance Approaches
Publisher: American Meteorological Society
Abstract: he impact of 8-day-averaged data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor?namely, the 1-km leaf area index, absorbed photosynthetic radiation, and land-use data?is investigated for use in the ...
An Evaluation of Snow Initializations in NCEP Global and Regional Forecasting Models
Publisher: American Meteorological Society
Abstract: now plays a major role in land?atmosphere interactions, but strong spatial heterogeneity in snow depth (SD) and snow water equivalent (SWE) makes it challenging to evaluate gridded snow quantities using in situ measurements. ...
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 ...
