An information system is presented destined for processing and systematized storage of the data of network sunphotometers. The system is designed in Builder C++ medium and includes individual program modules performing the following operations: calculation of instrumental functions of the photometer spectral channels, the transmission band functions of atmospheric gases, the aerosol optical depth, and columnar water vapor of the atmosphere; as well as filtration of the data distorted by cloudiness, determination of the aerosol microstructure parameters from the data on spectral transparency of the atmosphere.
