Abstract
The overall design of a radiometer and data acquisition system for use on an aircraft platform is described. The instrument is a fast response spectrally scanning radiometer providing measurements at 48 spectral intervals between 400 and 1200 nm. The radiometer has a narrow field of view in the nadir of approximately 7 mrad and a hemispheric field of view in the zenith. This paper describes the optical, mechanical and electronic design of the instrument and presents some early results from data gathered using the instrument on board the CSIRO F27 aircraft to illustrate its performance.
