Italy-Finland climate round trip with Python
summary
Italy and Finland get compared using daily gridded Copernicus reanalysis (0.25°) and SPEI12 from the Crosse store, spanning 1950–2024 for temperature and 2000–2025 for August SPEI; Python code ingests zipped NetCDFs via the CDS API, merges files, cleans -9999 values (Finland shows ~10% invalids), and computes spatial means, annual trends, medians and quantiles. Outputs include choropleths, annual time series, scatter and strike charts, and an interactive Jupyter notebook with sliders that spot long-term warming and critical drought years. xarray, GeoPandas, Cartopy, Plotly, Dask Copernicus Climate Data Store; NetCDF; CDS API
