Process Activity

Description: The process involves obtaining NUTS - Nomenclature of territorial units for statistics polygons for the relevant regions, followed by calling a public API with GPS coordinates derived from the polygons. A single API call is made per month, resulting in a gridded data response file with a default resolution of 0.1 degree latitude/longitude. Each month and region corresponds to one variable, resulting in over 20.000 files. The performance of this process is relatively slow, taking around a minute per call, and it requires a substantial number of calls to collect the complete dataset. There are over 12.000 raw input files in NetCDF4 format covering the period from 1990 to 2022.
