The trends of climatic characteristics in transitional landscape zones of the northern regions of Russia are considered. MODIS data are used for the analysis of surface spectral characteristics. In transitional landscape zones, climatic conditions are estimated on the basis of station data. In large geographical regions of the Russian North, the response of the spectral characteristics of landscapes to modern climatic changes is determined. The areas with the most significant changes of green phytomass are identified based on satellite data. Nowadays, the climatic conditions of some areas in tundra, forest tundra and northern taiga correspond to more southerly landscape zones. This can lead to a shift in the boundaries of transitional landscape zones to higher latitudes. Climatic changes are confirmed by the positive trends in the vegetation index in the tundra and forest-tundra zones in the European part of Russia for the period of 2000–2018. In Siberia, positive NDVI trends characterize the landscapes of forest tundra and northern taiga. The areas of the transitional forest-tundra zone with maximum changes in the spectral characteristics of the surface are distinguished: the Kola Peninsula, the western part of the Bolshezemelskaya tundra, Western and Eastern Siberia.
Keywords: climate change, landscape areas, MODIS, NDVI, albedo, surface temperature
