The ATMOSATLAND interactive system based on an IBM-PC/AT for receiving and processing of HRPT/NOAA data is presented. The software allows the mathematical processing for determination of: (a) Baltic Sea surface temperature; (b) soil surface temperature of the river basins; (c) vegetation index; (d) urban heat islands; (e) environmental changes of mining areas; (f) radiation budget; (g) three-dimensional distribution of the atmospheric temperature, moisture and ozone. The ATMOSATLAND system is also provided for processing of SPOT, LANDSAT and KOSMOS digital images.
