RISIn-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 ...
