is the PC based version of the Umkehr retrieval designed for the Brewer Umkehr measurements. The algorithm was originally developed for the Dobson Umkehr version (Petropavlovskikh et al. 2005). It was later (~2005) modified for the Brewer Umkehr measurements taken at ~310 and ~326 nm wavelength channels only.
