Realease notes

• December/2024: update grid (from 1961/01/01 to 2024/03/20, version "v_3.2.3"), with support from Climaterna project.

• June/2023: we adopt a new boundary for the grid, with a better fit to the coast of North East;  corrections in the gain and offset of NetCDF data to open properly in the software QGIS (version "v_3.2.2");

• April/2023: all ncfiles were created with smaller size (version "v_3.2.1");

• March/2023: update precipitation grid adding more rain gauges. Just for the  period 2001/01/01-2022/12/31 (version "v_3.1")
