Publisher: American Meteorological Society
Abstract: he Visible and Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-Orbiting Partnership satellite brings new opportunities for improving scientists? understanding of deep convective cloud (DCC) ...
Reducing Uncertainties of SNO-Estimated Intersatellite AMSU-A Brightness Temperature Biases for Surface-Sensitive Channels
Publisher: American Meteorological Society
Abstract: In this study, a technique has been developed to improve collocation of two passive-microwave satellite instrument datasets at a simultaneous nadir overpass (SNO). The technique has been designed for the purpose of reducing ...
Quantifying EOS Aqua and NOAA POES AMSU-A Brightness Temperature Biases for Weather and Climate Applications Utilizing the SNO Method
Publisher: American Meteorological Society
Abstract: Systematic biases between brightness temperature (Tb) measurements made from concurrently operational Advanced Microwave Sounding Unit-A (AMSU-A) instruments can introduce errors into weather and climate applications. For ...
Predicting Simultaneous Nadir Overpasses among Polar-Orbiting Meteorological Satellites for the Intersatellite Calibration of Radiometers
Publisher: American Meteorological Society
Abstract: A method for accurately predicting simultaneous nadir overpasses (SNOs) among different sun-synchronous polar-orbiting meteorological satellites is presented for intersatellite radiometer calibration. At each SNO, the ...
Intercalibration of GOES-11 and GOES-12 Water Vapor Channels with MetOp IASI Hyperspectral Measurements
Publisher: American Meteorological Society
Abstract: The calibrated radiances from geostationary water vapor channels play an important role for weather forecasting, data assimilation, and climate studies. Therefore, better understanding the data quality for radiance ...
Scene Radiance–Dependent Intersatellite Biases of HIRS Longwave Channels
Publisher: American Meteorological Society
Abstract: Measurements from the simultaneous nadir overpass (SNO) observations of the High Resolution Infrared Radiation Sounder (HIRS) are examined. The SNOs are the measurements taken at the orbital intersections of each pair of ...
Spectral Bias Estimation of Historical HIRS Using IASI Observations for Improved Fundamental Climate Data Records
Publisher: American Meteorological Society
Abstract: A prerequisite for climate change detection from satellites is that the measurements from a series of historical satellites must be consistent and ideally made traceable to the International System of Units (SI). Unfortunately, ...
Striping in the Suomi NPP VIIRS Thermal Bands through Anisotropic Surface Reflection
Publisher: American Meteorological Society
Abstract: he Visible Infrared Imaging Radiometer Suite (VIIRS) thermal emissive band (TEB) M12 images centered at 3.7 ?m were analyzed and unexpected striping was found. The striping was seen from ascending orbit (daytime) over ...
An Improved Algorithm for the Operational Calibration of the High-Resolution Infrared Radiation Sounder
Publisher: American Meteorological Society
Abstract: Radiance data from the High-Resolution Infrared Radiation Sounder (HIRS) have been used routinely in both direct radiance assimilation for numerical weather prediction and climate change detection studies. The operational ...
Assessing NOAA-16 HIRS Radiance Accuracy Using Simultaneous Nadir Overpass Observations from AIRS
Publisher: American Meteorological Society
Abstract: The High-Resolution Infrared Radiation Sounder (HIRS) has been carried on NOAA satellites for more than two decades, and the HIRS data have been widely used for geophysical retrievals, climate studies, and radiance ...
