- Аннотация: The accuracy of Land Surface Temperature (LST) products retrieved from satellite datain mountainous-coastal areas is not well understood. This study presents an analysis of the spatialand temporal variability of the differences between the LST and in situ observed air and surfacetemperatures (ISTs) for the southeastern slope of Lake Baikal’s surroundings. The IST was measuredat 12 ground observation sites located on the southeastern macro-slope of the Primorskiy Ridge(Baikal, Russia) within an elevation range of 460–1656 m above sea level from 2009 to 2021. LSTwas estimated using 617 Landsat (7 and 8) images from 2009–2021, taking into account brightnesstemperature, surface emissivity and vegetation cover fraction. The comparison of the LST fromsatellite data and the IST from ground observation showed relatively high differences, which varieddepending on the season and site type. A neural network was suggested and calibrated to improvethe LST data. The corrected remote-sensed temperature was found to reproduce the IST very well,with mean differences of about 0.03 ◦ C and linear correlation coefficients of 0.98 and 0.95 for the air and surface IST.
