Avec évolution de Février 2023 (A AMELIORER EVENTUELLEMENT) pour adaptation au format ERA5-Land-T (Timely updated, NearRealTime = nouvelle dimension 'expver')
https://confluence.ecmwf.int/display/CUSF/ERA5+CDS+requests+which+return+a+mixture+of+ERA5+and+ERA5T+data

https://confluence.ecmwf.int/display/CKB/ERA5-Land%3A+data+documentation

MONTHLY Precipitations, runoff, potential evaporation, evaporation, temperature and snow stock.

• Data: https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-land-monthly-means?tab=overview
• ERA5-Land Data documentation: https://confluence.ecmwf.int/display/CKB/ERA5-Land%3A+data+documentation

author: Loïc Duffar https://github.com/loicduffar

Run cells by order:

• 1) Data download (only NetCDF format here, because more handy than GRIB format)
• 1bis) IF the ERA5 file is already downloaded, start by the 2nd cell instead of the 1rst one
• 2) Customization, initialization and display netCDF file infos
• 3) Plot annual and monthly interannual average maps (and save to files)
• 4) Plot monthly time series (for one pixel and for a possible polygon), and export them to excel file
• 5) Annual maps animation OPTIONNAL
• 6) Montlhy maps animation OPTIONNAL
• 7) Plot Maps over 12 months for a specific year (and one month map with basemap) OPTIONNAL
• 8) Elevation map OPTIONNAL

HOURLY Precipitations, temperature, evaporation, runoff and other parameters.

Run cells in order :

• 1) Data download (Download volume is limited by the server: you will have to adapt number of variables, the périod of time and the area and/or to split the request in several files)
• 1bis) Edit and run the 2nd cell, instead of the 1rst one IF the ERA5 file is already downloaded
• 2) Customization, initialization and display netCDF file infos
• 3) Plot maps by hour/day/month and interannual average
• 4) Plot and export dailly time serie for one pixel and for a possible polygon
• 5) Animation maps by month, day and hour (OPTIONNAL)
• 5bis) Animation maps by day and hour OVER A SELECTED PERIOD OF TIME. (OPTIONNAL: Use this cell instead of the one above if the navigation through the hourly data is difficult because of a file covering a very long duration; 10 years for example).
