@linkalan90 To clarifiy a bit more: we tried directly contacting SMN (Servicio Meteorologico Nacional of Argentina) directly with inquiry about radar data. No response. If you know of anyone responsible or willing to provide more info/data, let us know and we'll gladly contact them.
Images provided at https://www.smn.gob.ar/radar are unfortunately in pretty low quality. Resolution isn't really great and there is a lot of unwanted clutter (city names, border lines, ...) placed over the radar data. Works for people directly, not so much when used separately.
