RISSelection of the 1.375-µm MODIS Channel for Remote Sensing of Cirrus Clouds and Stratospheric Aerosols from Space
Publisher: American Meteorological Society
Abstract: Using spectral imaging data acquired with the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) from an ER-2 aircraft at 20-km altitude during the NASA FIRE Phase II Cirrus field program, it was found that narrow ...
Surface-Induced Brightness Temperature Variations and Their Effects on Detecting Thin Cirrus Clouds Using IR Emission Channels in the 8 12-µm Region
Publisher: American Meteorological Society
Abstract: A method for detecting cirrus clouds in terms of brightness temperature differences between narrowbands at 8, 11, and 12 µm has been proposed by Ackerman et al. In this method, the variation of emissivity with wavelength ...
Improved Detection of Optically Thin Cirrus Clouds in Nighttime Multispectral Meteorological Satellite Imagery Using Total Integrated Water Vapor Information
Publisher: American Meteorological Society
Abstract: The accurate identification of optically thin cirrus clouds in global meteorological satellite imagery by automated cloud analysis algorithms is critical to environmental remote sensing studies, such as those related to ...
Distribution and Radiative Forcing of Tropical Thin Cirrus Clouds
Publisher: American Meteorological Society
Abstract: To understand the radiative impact of tropical thin cirrus clouds, the frequency of occurrence and optical depths of these clouds have been derived. ?Thin? cirrus clouds are defined here as being those that are not detected ...
Cloud Detection over the Arctic Region Using Airborne Imaging Spectrometer Data during the Daytime
Publisher: American Meteorological Society
Abstract: Detection of clouds over arctic regions from current satellite radiometric measurements in the visible and IR atmospheric window regions, such as those of Advanced Very High Resolution Radiometer and Landsat, is often ...
High Cloud Properties from Three Years of MODIS Terra and Aqua Collection-4 Data over the Tropics
Publisher: American Meteorological Society
Abstract: This study surveys the optical and microphysical properties of high (ice) clouds over the Tropics (30°S?30°N) over a 3-yr period from September 2002 through August 2005. The analyses are based on the gridded level-3 cloud ...
The O2/N2 Ratio and CO2 Airborne Southern Ocean Study
Publisher: American Meteorological Society
Abstract: AbstractThe Southern Ocean plays a critical role in the global climate system by mediating atmosphere?ocean partitioning of heat and carbon dioxide. However, Earth system models are demonstrably deficient in the Southern ...
