The Carpathian region, to which the research area belongs, is one of the most forested areas of Ukraine, and at the same time the most anthropogenically loaded. Studying the vegetation cover of the territories is currently one of the most important parameters that allows us to assess the state of the environment. The paper analyzes the change in the state of vegetation based on the NDVI index using Google Earth Engine (GEE) for the period between 2018 and 2023, with the construction of a difference index. The satellite image interpretation data allowed us to summarise the dynamics of the vegetation index change for two similar periods, in particular, for 2018 it is 0.464, for 2023 it is 0.330. The average difference value for the study area is 0.229. Taking into account dynamic climate change and its parameters such as precipitation, air temperature, surface temperature, wind speed, NDVI and NDWI indices, a correlation analysis was performed to identify the relationship between changes in vegetation cover and weather conditions. Statistical analysis of the data allowed us to identify the main groups of factors that have the greatest impact on the NDVI index, namely temperature and precipitation. However, the NDWI moisture index is in a clear inverse correlation, which confirms the significant impact of global temperatures on the unevenness of precipitation, especially during the 2018 floods. It is worth noting that the movement of air masses, which was determined through the average annual wind speed, gives an understanding of how changes in temperature above the ground affect the moisture content of vegetation.
