RISDiagnosing 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, ...
Understanding the Impacts of Land Surface and PBL Observations on the Terrestrial and Atmospheric Legs of Land–Atmosphere Coupling
Publisher: American Meteorological Society
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 ...
Assimilation of Satellite-Derived Skin Temperature Observations into Land Surface Models
Publisher: American Meteorological Society
Abstract: Land surface (or ?skin?) temperature (LST) lies at the heart of the surface energy balance and is a key variable in weather and climate models. In this research LST retrievals from the International Satellite Cloud Climatology ...
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 ...
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 ...
Assessing the Impact of L-Band Observations on Drought and Flood Risk Estimation: A Decision-Theoretic Approach in an OSSE Environment
Publisher: American Meteorological Society
Abstract: bserving system simulation experiments (OSSEs) are often conducted to evaluate the worth of existing data and data yet to be collected from proposed new missions. As missions increasingly require a broader ?Earth systems? ...
