Paper Abstract

The Ozone Meter (OM-2) described in this paper is designed to obtain both ozone profiles and cumulative ozone amount in the earth atmosphere from space measurements of solar backscatter ultraviolet radiation. OM-2 uses a filterwheel- photometer combination to measure UV radiation in the 252.0- 340.0 nm spectral region in 7 fixed wavelengths with 1.0 nm bandwidth. This short form report describes the OM-2 according to its optical scheme, detector, electronic parts, the filter wheel mechanism, the filters and the mechanical design. This technique can detect large variations of ozone a broad range of atmosphere with errors ranging up to 15 percent. The OM-2 instrument has small weight and size, low power consumption and an accuracy similar to that of more complicated instruments used in the past. The OM-2 will be a part of the instrument pack of the Israel microsatellite TechSat-1A that will be launched in 1997.
