RISImpact of Scene Dependence on AVHRR Albedo Models
Publisher: American Meteorological Society
Abstract: Narrowband observations from NOAA's Advanced Very High Resolution Radiometer (AVHRR) are used operationally by NOAA to estimate the earth's broadband planetary albedo. Since May of 1988; these broadband albedo estimates ...
Evaluating the Design of an Earth Radiation Budget Instrument with System Simulations. Part III: CERES-I Diurnal Sampling Error
Publisher: American Meteorological Society
Abstract: Accuracy estimates for the broadband CERES-I (Clouds and Earth's Radiant Energy System Instrument) measurements of daily average radiant exitance are presented. This is a continuation of the authors? earlier CERES sampling ...
Evaluating the Design of an Earth Radiation Budget Instrument with System Simulations. Part I: Instantaneous Estimates
Publisher: American Meteorological Society
Abstract: A set of system simulations has been performed to evaluate candidate scanner designs for an Earth Radiation Budget Instrument (ERBI) for the Earth Observing System (EOS) of the late 1990s. Five different instruments are ...
Evaluating the Design of an Earth Radiation Budget Instrument with System Simulations. Part II: Minimization of Instantaneous Sampling Errors for CERES-I
Publisher: American Meteorological Society
Abstract: Much of the new record of broadband earth radiation budget satellite measurements to be obtained during the late 1990s and early twenty-first century will come from the dual-radiometer Clouds and Earth's Radiant Energy ...
The Constrained Inversion of Nimbus-7 Wide Field-of-View Radiometer Measurements for the Earth Radiation Budget
Publisher: American Meteorological Society
Abstract: The results of a constrained, wide field-of-view (WFOV) radiometer measurement deconvolution are presented and compared against higher resolution results obtained from the Earth Radiation Budget (ERB) Experiment on the ...
In-Flight Calibration of the Nimbus-7 Earth Radiation Budget (ERB) Sensors. Part I: A Thermal Model for the Shortwave Channels
Publisher: American Meteorological Society
Abstract: Much of the early record of spectrally broadband earth radiation budget (ERB) measurements was taken by the ERB instrument launched on the Nimbus-7 spacecraft in October 1978. The wide-field-of-view (WFOV) sensors measured ...
In-Flight Calibration of the Nimbus-7 Earth Radiation Budget (ERB) Sensors. Part II: Short-Term Perturbations
Publisher: American Meteorological Society
Abstract: This paper describes the production calibration adjustment algorithms used to remove thermal perturbation and stray light noise signals from the Nimbus-7 earth radiation budget (ERB) measurements. Sunlight, both direct and ...
In-Flight Calibration of the Nimbus-7 Earth Radiation Budget (ERB) Sensors. Part III: Long-Term Changes
Publisher: American Meteorological Society
Abstract: Sensitivity changes in the four wide-field-of-view (WFOV) Nimbus-7 earth radiation budget (ERB) sensors were monitored over a 9-yr period (November 1978?October 1987) by use of a number of reference sources. The sun was ...
