Improved Calibration Coefficients for NOAA-12 and NOAA-15 AVHRR Visible and Near-IR Channels
Publisher: American Meteorological Society
Abstract: A time history of the calibration coefficients for channels 1 and 2 of the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-12 and NOAA-15 spacecraft is presented. The history is based on reflectances observed ...
Using Sun Glint to Check the Relative Calibration of Reflected Spectral Radiances
Publisher: American Meteorological Society
Abstract: Observations of sunlight reflected from regions of sun glint are used to check the relative calibration of spectral radiances obtained with imaging radiometers. Reflectances at different wavelengths for sun-glint regions ...
Morning-to-Afternoon Evolution of Marine Stratus Polluted by Underlying Ships: Implications for the Relative Lifetimes of Polluted and Unpolluted Clouds
Publisher: American Meteorological Society
Abstract: Ship tracks appearing in both the morning and afternoon Moderate Resolution Imaging Spectroradiometer (MODIS) imagery for the Pacific Ocean off the west coast of the United States were used to study the morning-to-afternoon ...
Retrieval of Cloud Properties for Partly Cloudy Imager Pixels
Publisher: American Meteorological Society
Abstract: Retrievals of cloud properties from satellite imagery often invoke the assumption that the fields of view are overcast when cloud-contaminated, even though a significant fraction are only partially cloud-covered. The ...
MODIS Observations of Ship Tracks in Summertime Stratus off the West Coast of the United States
Publisher: American Meteorological Society
Abstract: Three years of 1-km Moderate Resolution Imaging Spectroradiometer (MODIS) observations for morning (Terra) and afternoon (Aqua) summertime marine stratus off the west coast of the United States were analyzed to determine ...
Effects of Aerosols on the Radiative Properties of Clouds
Publisher: American Meteorological Society
Abstract: The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the ...
