RISRadiometric and Spectral Characteristics of the ScaRaB-3 Instrument on Megha-Tropiques: Comparisons with ERBE, CERES, and GERB
Publisher: American Meteorological Society
Abstract: The Indian?French Megha-Tropiques mission, scheduled to be launched in 2010, will carry radiation and microwave sensors to study the energy and water cycle in the tropics. The radiation sensor, the third model of the Scanner ...
True Along-Track Scan to Improve Radiation Budget Estimations
Publisher: American Meteorological Society
Abstract: Multiangle approaches for radiance-to-flux conversion require accurate coregistration between the observations from nadir- and oblique-viewing directions. The along-track mode of Earth Radiation Budget (ERB) scanning ...
Determination of Shortwave Earth Reflectances from Visible Radiance Measurements: Error Estimate Using ScaRaB Data
Publisher: American Meteorological Society
Abstract: The error resulting from the use of a visible channel to estimate shortwave (SW) (0.2?4 ?m) fluxes reflected by the earth is analyzed. First, the authors compute regression coefficients between visible (0.55?0.65 ?m) and ...
Top-of-Atmosphere Radiance-to-Flux Conversion in the SW Domain for the ScaRaB-3 Instrument on Megha-Tropiques
Publisher: American Meteorological Society
Abstract: The earth radiation budget (ERB) is the difference between the solar absorbed flux and the terrestrial emitted flux. These fluxes are calculated from satellite measurements of outgoing shortwave (SW) and longwave (LW) ...
Regional Diurnal Albedo Climatology and Diurnal Time Extrapolation of Reflected Solar Flux Observations: Application to the ScaRaB Record
Publisher: American Meteorological Society
Abstract: A regional (2.5° ? 2.5° resolved) diurnal (hourly) albedo climatology for low and midlatitudes is derived for each month from the 5?-yr narrow-field-of-view data record obtained from the Earth Radiation Budget Satellite ...
