Regional Flux Estimation in a Convective Boundary Layer Using a Conservation Approach
Publisher: American Meteorological Society
Abstract: During the Southern Great Plains 1997 Hydrology Experiment, a tethersonde system was deployed at the U.S. Department of Energy?s Atmospheric Radiation Measurement Cloud and Radiation Test Bed (ARM CART) central facility. ...
Real-Time Bias Reduction for Satellite-Based Precipitation Estimates
Publisher: American Meteorological Society
Abstract: A new approach to reduce biases in satellite-based estimates in real time is proposed and tested in this study. Currently satellite-based precipitation estimates exhibit considerable biases, and there have been many efforts ...
Diagnosing the Sensitivity of Local Land–Atmosphere Coupling via the Soil Moisture–Boundary Layer Interaction
Publisher: American Meteorological Society
Abstract: he inherent coupled nature of earth?s energy and water cycles places significant importance on the proper representation and diagnosis of land?atmosphere (LA) interactions in hydrometeorological prediction models. However, ...
Multitemporal Analysis of TRMM-Based Satellite Precipitation Products for Land Data Assimilation Applications
Publisher: American Meteorological Society
Abstract: In this study, the recent work of Gottschalck et al. and Ebert et al. is extended by assessing the suitability of two Tropical Rainfall Measuring Mission (TRMM)-based precipitation products for hydrological land data ...
A Modeling and Observational Framework for Diagnosing Local Land–Atmosphere Coupling on Diurnal Time Scales
Publisher: American Meteorological Society
Abstract: Land?atmosphere interactions play a critical role in determining the diurnal evolution of both planetary boundary layer (PBL) and land surface temperature and moisture states. The degree of coupling between the land surface ...
Role of Subsurface Physics in the Assimilation of Surface Soil Moisture Observations
Publisher: American Meteorological Society
Abstract: Root-zone soil moisture controls the land?atmosphere exchange of water and energy, and exhibits memory that may be useful for climate prediction at monthly scales. Assimilation of satellite-based surface soil moisture ...
Evaluation of GSMaP Precipitation Estimates over the Contiguous United States
Publisher: American Meteorological Society
Abstract: Precipitation estimates from the Global Satellite Mapping of Precipitation (GSMaP) project are evaluated over the contiguous United States (CONUS) for the period of 2005?06. GSMaP combines precipitation retrievals from the ...
Impacts of High-Resolution Land Surface Initialization on Regional Sensible Weather Forecasts from the WRF Model
Publisher: American Meteorological Society
Abstract: This manuscript presents an assessment of daily regional simulations of the Weather Research and Forecasting (WRF) numerical weather prediction (NWP) model initialized with high-resolution land surface data from the NASA ...
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 ...
Impact of Soil Moisture Assimilation on Land Surface Model Spinup and Coupled Land–Atmosphere Prediction
Publisher: American Meteorological Society
Abstract: dvances in satellite monitoring of the terrestrial water cycle have led to a concerted effort to assimilate soil moisture observations from various platforms into offline land surface models (LSMs). One principal but still ...
