RISSea Ice Concentration Analyses for the Baltic Sea and Their Impact on Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: Sea ice concentration plays a fundamental role in the exchange of water and energy between the ocean and the atmosphere. Global real-time datasets of sea ice concentration are based on satellite observations, which do not ...
Assimilation of Screen-Level Variables in ECMWF’s Integrated Forecast System: A Study on the Impact on the Forecast Quality and Analyzed Soil Moisture
Publisher: American Meteorological Society
Abstract: In many operational numerical weather prediction applications, the soil moisture analysis is based on the modeled first-guess and screen-level variables; that is, 2-m temperature and 2-m relative humidity. A set of two ...
ECMWF's Global Snow Analysis: Assessment and Revision Based on Satellite Observations
Publisher: American Meteorological Society
Abstract: Snow water equivalent and snow extent are key parameters for the earth's energy and water budget. In this study, the current operational snow-depth analysis (2D spatial Cressman interpolation) at the European Centre for ...
Vegetative and Atmospheric Corrections for the Soil Moisture Retrieval from Passive Microwave Remote Sensing Data: Results from the Southern Great Plains Hydrology Experiment 1997
Publisher: American Meteorological Society
Abstract: A radiative transfer model and data from the Southern Great Plains 1997 Hydrology Experiment were used to analyze the dependency of surface emissivity retrieval at 19 GHz on atmospheric and vegetative effects. Volumetric ...
Comparing ERA-40-Based L-Band Brightness Temperatures with Skylab Observations: A Calibration/Validation Study Using the Community Microwave Emission Model
Publisher: American Meteorological Society
Abstract: The Community Microwave Emission Model (CMEM) has been used to compute global L-band brightness temperatures at the top of the atmosphere. The input data comprise surface fields from the 40-yr ECMWF Re-Analysis (ERA-40), ...
Effects of the Near-Surface Soil Moisture Profile on the Assimilation of L-band Microwave Brightness Temperature
Publisher: American Meteorological Society
Abstract: The impact of model and observation errors in the European Land Data Assimilation System (ELDAS) data assimilation system on the analyzed surface variables has been studied using the Southern Great Plains Hydrology Experiment ...
Using a Microwave Emission Model to Estimate Soil Moisture from ESTAR Observations during SGP99
Publisher: American Meteorological Society
Abstract: The 1999 Southern Great Plains Hydrology Experiment (SGP99) provides comprehensive datasets for evaluating microwave remote sensing of soil moisture algorithms that involve complex physical properties of soils and vegetation. ...
Copula-Derived Observation Operators for Assimilating TMI and AMSR-E Retrieved Soil Moisture into Land Surface Models
Publisher: American Meteorological Society
Abstract: Assimilating soil moisture from satellite remote sensing into land surface models (LSMs) has potential for improving model predictions by providing real-time information at large scales. However, the majority of the research ...
Optimized Surface Radiation Fields Derived from Meteosat Imagery and a Regional Atmospheric Model
Publisher: American Meteorological Society
Abstract: High-quality fields of surface radiation fluxes are required for the development of Land Data Assimilation Systems. A fast offline integration scheme was developed to modify NWP model cloud fields based on Meteosat visible ...
