Paper Abstract

Study of NDVI (Normalized Difference Vegetation Index) in Eastern Siberia was carried out on long-term (1982-2014) satellite data. 15-days average NDVI data (GIMMS project) was used to create the maps of NDVI trends distribution and correlation of NDVI with air temperature and precipitation. Using NDVI daily data (NOAA CDR Program data) over three test sites (in Yakutia), phenological parameters of tundra vegetation and deciduous needleleaf forests were calculated. It is shown, that for past three decades there is a positive NDVI trend in Eastern Siberia. Analysis of phenological parameters shows a tendency of an earlier SOS (start of season) and later EOS (end of season) for deciduous needleleaf forests and tundra vegetation. Air temperature is the major factor that defines positive trend of NDVI vegetation index under conditions of low precipitation.
