IHR (Infrared Heterodyne Radiometer) for Low Altitude Temperature Profile Retrieval.

Abstract

A technique for obtaining accurate temperature and humidity profiles with a grazing-angle up-looking radiometer, for the purpose of assessing index of refraction variations in the atmosphere has been investigated. The profiling techniques is based on information retrievals which are obtained from difference-kernel functions generated from pairs of high spectral resolution radiometric channels. Spatially selective information can be generated from such functions with the required accuracy for retrieving temperature and humidity gradients at the lower altitude atmospheric levels.
