@gkikas-lgpz Thanks - that's what I've found as well. I'm looking for a link to the raw files. I've emailed BMKG and get no response. I was trying a link that I found here: https://community.windy.com/topic/3746/radar-data-needed-help-us-with-the-data-gathering/18?lang=en-GB

This was the post:
Dear @TomSlavkovsky , here I give you the link to BMKG (Indonesia) radar data archive (also real time data included). They are in NetCDF *.gz format. Please use this link to see how the data is like, site is open (no login or payment needed).

http://radar.bmkg.go.id/bmkg2/data/

But the link provided isn't working. I'm looking for an updated link.

Thanks again!
