• In Google Earth Engine, Information here. Simple example in the Jupyter, here.

Realease notes:

• 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 (versions "v_3.2.2");

• April/2023: all ncfiles were created with smaller size (versions "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")
