RISComputation of Radiation Budget on an Oblate Earth
Publisher: American Meteorological Society
Abstract: he effects of the earth?s oblateness on computation of its radiation budget from satellite measurements are evaluated. For the Clouds and the Earth?s Radiant Energy System (CERES) data processing, geolocations of the ...
The Annual Cycle of Earth Radiation Budget from Clouds and the Earth’s Radiant Energy System (CERES) Data
Publisher: American Meteorological Society
Abstract: he seasonal cycle of the Earth radiation budget is investigated by use of data from the Clouds and the Earth?s Radiant Energy System (CERES). Monthly mean maps of reflected solar flux and Earth-emitted flux on a 1° equal-angle ...
Assessment of the Visible Channel Calibrations of the VIRS on TRMM and MODIS on Aqua and Terra
Publisher: American Meteorological Society
Abstract: Several recent research satellites carry self-calibrating multispectral imagers that can be used for calibrating operational imagers lacking complete self-calibrating capabilities. In particular, the visible (VIS, 0.65 ?m) ...
Rapid Calibration of Operational and Research Meteorological Satellite Imagers. Part I: Evaluation of Research Satellite Visible Channels as References
Publisher: American Meteorological Society
Abstract: Operational meteorological satellites generally lack reliable onboard calibration systems for solar-imaging channels. Current methods for calibrating these channels and for normalizing similar channels on contemporaneous ...
Rapid Calibration of Operational and Research Meteorological Satellite Imagers. Part II: Comparison of Infrared Channels
Publisher: American Meteorological Society
Abstract: To establish a more reliable reference instrument for calibration normalization, this paper examines the differences between the various thermal infrared imager channels on a set of research and operational satellites. ...
Angular Distribution Models for Top-of-Atmosphere Radiative Flux Estimation from the Clouds and the Earth’s Radiant Energy System Instrument on the Terra Satellite. Part II: Validation
Publisher: American Meteorological Society
Abstract: Errors in top-of-atmosphere (TOA) radiative fluxes from the Clouds and the Earth?s Radiant Energy System (CERES) instrument due to uncertainties in radiance-to-flux conversion from CERES Terra angular distribution models ...
CERES Synoptic Product: Methodology and Validation of Surface Radiant Flux
Publisher: American Meteorological Society
Abstract: he Clouds and the Earth?s Radiant Energy System Synoptic (SYN1deg), edition 3, product provides climate-quality global 3-hourly 1° ? 1°gridded top of atmosphere, in-atmosphere, and surface radiant fluxes. The in-atmosphere ...
Observed Sensitivity of Low-Cloud Radiative Effects to Meteorological Perturbations over the Global Oceans
Publisher: American Meteorological Society
Abstract: Understanding how marine low clouds and their radiative effects respond to changing meteorological conditions is crucial to constrain low-cloud feedbacks to greenhouse warming and internal climate variability. In this ...
Toward Optimal Closure of the Earth's Top-of-Atmosphere Radiation Budget
Publisher: American Meteorological Society
Abstract: Despite recent improvements in satellite instrument calibration and the algorithms used to determine reflected solar (SW) and emitted thermal (LW) top-of-atmosphere (TOA) radiative fluxes, a sizeable imbalance persists in ...
Surface Irradiances Consistent with CERES-Derived Top-of-Atmosphere Shortwave and Longwave Irradiances
Publisher: American Meteorological Society
Abstract: he estimate of surface irradiance on a global scale is possible through radiative transfer calculations using satellite-retrieved surface, cloud, and aerosol properties as input. Computed top-of-atmosphere (TOA) irradiances, ...
