Popis:	Considered is a new method of remote derivation of the land surface temperature (LST) Ts using data of nonsimultaneous measurements of the SEVIRI/Meteosat-9 instrument in channels of transparency windows of 10.5–12.5 μm in the case of the cloudiness absence in the field of instrument. The method is the combination of two well-known algorithms of the subject processing of satellite data. It enables to derive Ts without the involvement of data on the values of the land emissivity at sounding stations. Experiments on the processing of SEVIRI actual data of some autumn days of 2008, as well as a comparison of the results with independent satellite estimations of Ts, confirm the operability and efficiency of the proposed method. The possibility of detailed description of the diurnal course of LST on the basis of SEVIRI data using the proposed method of Ts estimation is analyzed.
