Recent Trends in Land Surface Phenologies Within the Don and Dnieper River Basins from the Perspective of MODIS Collection 4 Products
During the past 2 decades Eastern Europe has been going through one of the most abrupt socioeconomic transformations in recent times. As core areas for regional agricultural production, the basins of the Dnieper and Don Rivers, the institutional changes have impacted the terrestrial vegetation cover dynamics. As regional economies entered recovery phases starting around the year 2000, the observed trends in land surface phenologies have, in some locations, changed their previous downward direction. We analyze here image time series of MODIS Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature from Collection 4 data products. Our main objective is to characterize and summarize the extent of negative and positive trends in land surface phenologies across the study area and draw linkages between trends in indicators of surface vegetation and those in the radiometric skin temperature.
