“…Besides acting as a support for the instrument, the carousel also holds several reference detectors' a reference active cavity radiometer (ACR) and a reference solar monitor. These reference detectors are used to transfer the calibration from the MRBB to the integrating sphere and are described in more detail by Hesser and Potter [1983]. A counterbalance weight is used on the carousel opposite the instrument for stability.…”

Orbital measurements of the earth's radiation budget are being made from several spacecraft launched in the latter part of 1984. Three sets of instruments have been designed to measure the incident solar flux, the earth's long-wave emitted radiation, and the earth's reflected radiation more accurately than have been measured before. These instruments consist of a three-channel narrow field of view scanning radiometer and a four-channel wide field of view staring nonscanner radiometer and a solar channel. The instruments are collecting data on spectral, spatial, and temporal scales specified by scientists and researchers in the weather and climate discipline. The scanning radiometer, the subject of this paper, is designed to yield small-scale definition for measurements taken bY the nonscanner and thereby test convolution/deconvolution techniques used on wide field of view data. The scanning radiometer is also expected to yield bidirectional reflectance data as an aid in radiation transfer modeling calculations.

Two Earth Radiation Budget Experiment (ERBE) nonscanner instruments are flying with companion scanner instruments to measure the earth's energy budget from low earth orbit. A third set of instruments will be launched in March 1986. This program is the first designed to make a comprehensive set of highly accurate measurements of the earth's ene. rgy budget on the spectral, spatial, and temporal scales specified by the scientific community for use in climatological research. The ERBE nonscanner combines the use of the highly accurate active cavity radiometer (ACR) detector with a comprehensive preflight calibration and characterization program and a design which includes operational flexibility and in-flight calibration checks to achieve and maintain, throughout its 2-year design life, a measurement accuracy capability not previously possible. This paper describes the ERBE nonscanner instrument, its operation, calibration, and mission profile.
