Evaluation of Fractional Cloudiness Parameterizations for Use in a Mesoscale Model
Publisher: American Meteorological Society
Abstract: The Regional Atmospheric Modeling System (RAMS), developed at Colorado State University, was used to predict boundary-layer clouds and diagnose fractional cloudiness. The primary case study for this project occurred on 7 ...
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 ...
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 ...
Diagnosing an Artificial Trend in NLDAS-2 Afternoon Precipitation
Publisher: American Meteorological Society
Abstract: hile investigating linkages between afternoon peak rainfall amount and land?atmosphere coupling strength, a statistically significant trend in phase 2 of the North American Land Data Assimilation System (NLDAS-2) warm ...
A Multimodel Analysis for the Coordinated Enhanced Observing Period (CEOP)
Publisher: American Meteorological Society
Abstract: A collection of eight operational global analyses over a 27-month period have been processed to common data structures to facilitate comparisons among the analyses and global observational datasets. The present study ...
Impact of Vegetation Assimilation on Flash Drought Characteristics across the Continental United States
Publisher: American Meteorological Society
Quantifying the Importance of Selected Drought Indicators for the United States Drought Monitor
Publisher: American Meteorological Society
Quantifying the Added Value of Snow Cover Area Observations in Passive Microwave Snow Depth Data Assimilation
Publisher: American Meteorological Society
Abstract: ccurate determination of snow conditions is important for several water management applications, partly because of the significant influence of snowmelt on seasonal streamflow prediction. This article examines an approach ...
Benchmarking NLDAS-2 Soil Moisture and Evapotranspiration to Separate Uncertainty Contributions
Publisher: American Meteorological Society
Abstract: odel benchmarking allows us to separate uncertainty in model predictions caused by model inputs from uncertainty due to model structural error. This method is extended with a ?large sample? approach (using data from multiple ...
Comparing Evaporative Sources of Terrestrial Precipitation and Their Extremes in MERRA Using Relative Entropy
Publisher: American Meteorological Society
Abstract: quasi-isentropic, back-trajectory scheme is applied to output from the Modern-Era Retrospective Analysis for Research and Applications (MERRA) and a land-only replay with corrected precipitation to estimate surface evaporative ...
