Seasonal Trend Analysis of MODIS-EVI time series over Europe (2000-2020)

There is growing interest in the macro-scale responses of biomes and ecoregions to processes related to global change. Concerning that, there is increasing evidence associating vegetation and land cover changes with warmer temperatures and land-use changes. From the mid-1980s onwards, satellite data has been used to study these processes. In this connection, we analyzed the monthly time series from 2000 to 2020 of the Enhanced Vegetation Index (EVI) from the Moderate Resolution Imaging Spectroradiometer (MODIS) products by using Seasonal Trend Analysis (STA). Preliminary results evidence from 2000 to 2020, most of the European territory (~70%) has experienced significant trends (p < 0.05) in the seasonality of EVI, mainly with an increase in greenness. Future works should analyse trends at biomes and ecoregions scales and evaluate the statistical significance of the observed trends in gridded data.
