INVESTIGATION OF THE INFRARED EMISSION SPECTRUM OF THE ATMOSPHERE AND EARTH

Abstract

A transportable grating spectrometer and an actinograph working with interference filters were constructed in order to investigate the infrared sky radiation in dependence of different meteorological conditions. The spectrometer is equipped with an echelette grating. By choise gratings with a blaze at 10, 12 or 20 microns can be used. It makes possible measurements of sky or ground emission spectra and of the difference between two radiation fluxes. The interference-filter actinograph is mainly an auxiliary equipment to control the total water vapour content of the atmosphere. The design of the instruments, calibration procedures and the performance of measurements are described. (Author)
