RISA Coupled Land Surface–Boundary Layer Model and Its Adjoint
Publisher: American Meteorological Society
Abstract: In this paper, a simple coupled land surface?boundary layer model and its adjoint are presented. The primary goal is to demonstrate the capabilities of the adjoint model as a general tool for sensitivity analysis and data ...
Feedback between the Land Surface Energy Balance and Atmospheric Boundary Layer Diagnosed through a Model and Its Adjoint
Publisher: American Meteorological Society
Abstract: In this paper, the differences in (daytime) sensitivity of surface turbulent fluxes to states and parameters for a coupled land?atmospheric boundary layer model in coupled and uncoupled modes are investigated using an ...
Variational Assimilation of Radiometric Surface Temperature and Reference-Level Micrometeorology into a Model of the Atmospheric Boundary Layer and Land Surface
Publisher: American Meteorological Society
Abstract: Data assimilation provides a useful framework that allows us to combine measurements and models, by appropriately weighting the sources of error in both, to produce a statistically optimal and dynamically consistent estimate ...
Feasibility Test of Multifrequency Radiometric Data Assimilation to Estimate Snow Water Equivalent
Publisher: American Meteorological Society
Abstract: A season-long, point-scale radiometric data assimilation experiment is performed in order to test the feasibility of snow water equivalent (SWE) estimation. Synthetic passive microwave observations at Special Sensor Microwave ...
Investigating the Impact of Soil Moisture and Atmospheric Stability on Cloud Development and Distribution Using a Coupled Large-Eddy Simulation and Land Surface Model
Publisher: American Meteorological Society
Abstract: he influence of soil moisture and atmospheric thermal stability on surface fluxes, boundary layer characteristics, and cloud development are investigated using a coupled large-eddy simulation (LES)?land surface model (LSM) ...
Investigating the Variability of High-Elevation Seasonal Orographic Snowfall Enhancement and Its Drivers across Sierra Nevada, California
Publisher: American Meteorological Society
Abstract: AbstractWhile orographically driven snowfall is known to be important in mountainous regions, a complete understanding of orographic enhancement from the basin to the mountain range scale is often inhibited by limited ...
A Comparison of the Triangle Retrieval and Variational Data Assimilation Methods for Surface Turbulent Flux Estimation
Publisher: American Meteorological Society
Abstract: Future operational frameworks for estimating surface turbulent fluxes over the necessary spatial and temporal scales will undoubtedly require the use of remote sensing products. Techniques used to estimate surface fluxes ...
Validation and Error Characterization of the GPCP-1DD Precipitation Product over the Contiguous United States
Publisher: American Meteorological Society
Abstract: A validation and error characterization study of the Global Precipitation Climatology Project, 1 degree daily (GPCP-1DD) precipitation product over the contiguous United States is presented. Daily precipitation estimates ...
