RISLand Surface Microwave Emissivities over the Globe for a Decade
Publisher: American Meteorological Society
Abstract: Microwave land surface emissivities have been calculated over the globe for ?10 yr between 19 and 85 GHz at 53° incidence angle for both orthogonal polarizations, using satellite observations from the Special Sensor Microwave ...
The Assimilation of Observations from the Advanced Microwave Sounding Unit over Sea Ice in the French Global Numerical Weather Prediction System
Publisher: American Meteorological Society
Abstract: he aim of this study is to test the feasibility of assimilating microwave observations from the Advanced Microwave Sounding Units (AMSU-A and AMSU-B) through the implementation of an appropriate parameterization of sea ice ...
A Long-Term, High-Resolution Wetland Dataset over the Amazon Basin, Downscaled from a Multiwavelength Retrieval Using SAR Data
Publisher: American Meteorological Society
Abstract: climatology of wetlands has been derived at a low spatial resolution (0.25° ? 0.25° equal-area grid) over a 15-yr period by combining visible and near-infrared satellite observations and passive and active microwaves. The ...
Comparisons of the Millimeter and Submillimeter Bands for Atmospheric Temperature and Water Vapor Soundings for Clear and Cloudy Skies
Publisher: American Meteorological Society
Abstract: Geostationary satellites provide revisiting times that are desirable for nowcasting and observations of severe weather. To overcome the problem of spatial resolution from a geostationary orbit, millimeter to submillimeter ...
An Innovative Calibration Method for the Inversion of Satellite Observations
Publisher: American Meteorological Society
Abstract: Retrieval schemes often use two important components: 1) a radiative transfer model (RTM) inside the retrieval procedure or to construct the learning dataset for the training of the statistical retrieval algorithms and 2) ...
AMSU-A Land Surface Emissivity Estimation for Numerical Weather Prediction Assimilation Schemes
Publisher: American Meteorological Society
Abstract: This study describes the work performed at the European Centre for Medium-Range Weather Forecasts (ECMWF) to estimate the microwave land surface emissivities at Advanced Microwave Sounding Unit (AMSU)-A frequencies within ...
A Land and Ocean Microwave Cloud Classification Algorithm Derived from AMSU-A and -B, Trained Using MSG-SEVIRI Infrared and Visible Observations
Publisher: American Meteorological Society
Abstract: statistical cloud classification and cloud mask algorithm is developed based on Advanced Microwave Sounding Unit (AMSU-A and -B) microwave (MW) observations. The visible and infrared data from the Meteosat Third ...
Comparisons of Global Terrestrial Surface Water Datasets over 15 Years
Publisher: American Meteorological Society
Abstract: ontinental surface water extents and dynamics are key information to model Earth?s hydrological and biochemical cycles. This study presents global and regional comparisons between two multisatellite surface water extent ...
A Global Dynamic Long-Term Inundation Extent Dataset at High Spatial Resolution Derived through Downscaling of Satellite Observations
Publisher: American Meteorological Society
Abstract: new procedure is introduced to downscale low-spatial-resolution inundation extents from Global Inundation Extent from Multi-Satellites (GIEMS) to a 3-arc-s (90 m) dataset (known as GIEMS-D3). The methodology is based on ...
Characterization and Space–Time Downscaling of the Inundation Extent over the Inner Niger Delta Using GIEMS and MODIS Data
Publisher: American Meteorological Society
Abstract: he objective in this work is to develop downscaling methodologies to obtain a long time record of inundation extent at high spatial resolution based on the existing low spatial resolution results of the Global Inundation ...
