Temporal Evolution of Seasonal Crop‐Specific Climatic Indices in Greece, Based on ERA- and CMIP6- derived Data

This study presents an updated temporal evolution of seasonal crop‐specific climatic indices in Greece, based on ERA5- and CMIP6- derived temperature and precipitation data. The indices include days with (a) daily maximum air temperature Tmax> 30◦C in spring (HD30spr) and Tmax>35◦C in summer (HD35sum), respectively, (b) daily minimum air temperature Tmin< 0 °C (frost days) in spring and (c) spring and summer precipitation of the reference period (1950-2023) and in the near future (2024-2050) (NF). The climatic indices related to Tmax (Tmin) presented increasing (decreasing) trends, with both ERA5 and CMIP6 data, towards the present and strong (weak) increases in the NF. Precipitation showed statistically weak decreasing trends in spring, increasing trends in summer, and weak decreasing trends for both seasons in the NF.
