RISVicarious Calibration of an Ocean Salinity Radiometer from Low Earth Orbit
Publisher: American Meteorological Society
Abstract: Statistical properties of the brightness temperature (TB) measured by a low-earth-orbiting radiometer operating at 1.4 GHz are considered as a means of calibrating and validating the sensor. Mapping of ocean salinity by ...
Estimating Tropical Cyclone Integrated Kinetic Energy with the CYGNSS Satellite Constellation
Publisher: American Meteorological Society
Abstract: he Cyclone Global Navigation Satellite System (CYGNSS) constellation is designed to provide observations of surface wind speed in and near the inner core of tropical cyclones with high temporal resolution throughout the ...
Determining Tropical Cyclone Surface Wind Speed Structure and Intensity with the CYGNSS Satellite Constellation
Publisher: American Meteorological Society
Abstract: YGNSS?the Cyclone Global Navigation Satellite System?consists of a constellation of eight microsatellites which will provide observations of surface wind speed in all precipitating conditions. A method for estimating ...
A Coupled-Pixel Model (CPM) Atmospheric Retrieval Algorithm for High-Resolution Imagers
Publisher: American Meteorological Society
Abstract: ow-frequency passive microwave observations allow for oceanic remote sensing of surface wind speed and rain rate from spaceborne and airborne platforms. For most instruments, the modeling of contributions of rain absorption ...
Determination of an Amazon Hot Reference Target for the On-Orbit Calibration of Microwave Radiometers
Publisher: American Meteorological Society
Abstract: A physically based model is developed to determine hot calibration reference brightness temperatures (TBs) over depolarized regions in the Amazon rain forest. The model can be used to evaluate the end-to-end calibration ...
Atmospheric Profiling of Water Vapor Density with a 20.5–23.5 GHz Autocorrelation Radiometer
Publisher: American Meteorological Society
Abstract: A tropospheric water vapor density profiling system is presented. The hardware consists of an autocorrelation radiometer (CORRAD) operating over a frequency range from 20.5 to 23.5 GHz. The CORRAD directly measures the ...
Validation and Development of Melting Layer Models Using Constraints by Active/Passive Microwave Observations of Rain and the Wind-Roughened Ocean Surface
Publisher: American Meteorological Society
Abstract: A physically based method is developed to estimate the microphysical structure of the melting layer in stratiform rain using airborne observations by a dual-frequency radar and a 10.7-GHz radiometer. The method employs a ...
Bayesian Wind Speed Estimation Conditioned on Significant Wave Height for GNSS-R Ocean Observations
Publisher: American Meteorological Society
Abstract: paceborne GNSS-Reflectometry observations of the ocean surface are found to respond to components of roughness forced by local winds, and to longer wave swell that is only partially correlated with the local wind. This ...
Sampled Together: Assessing the Value of Simultaneous Collocated Measurements for Optimal Satellite Configurations
Publisher: American Meteorological Society
Land Contamination Correction for Passive Microwave Radiometer Data: Demonstration of Wind Retrieval in the Great Lakes Using SSM/I
Publisher: American Meteorological Society
Abstract: assive microwave radiometer data over the ocean have been widely used, but data near coastlines or over lakes often cannot be used because of the large footprint with mixed signals from both land and water. For example, ...
