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 ...
Measurement of Broadband Diffuse Solar Irradiance Using Current Commercial Instrumentation with a Correction for Thermal Offset Errors
Publisher: American Meteorological Society
Abstract: Diffuse-sky solar irradiance is an important quantity for radiation budget research, particularly as it relates to climate. Diffuse irradiance is one component of the total downwelling solar irradiance and contains information ...
The Baseline Surface Radiation Network Pyrgeometer Round-Robin Calibration Experiment
Publisher: American Meteorological Society
Abstract: With the aim of improving the consistency of terrestrial and atmospheric longwave radiation measurements within the Baseline Surface Radiation Network, five Eppley Precision Infrared Radiometer (PIR) pyrgeometers and one ...
