@Dinar-Meraleev Great, thank you. I've got reply from meteo department at Tbilisi int. airport. So far, they seem to be interested and helpful. I still don't know what format, which radar sites and how often and with what delay we'll get the data, but it seems that we might get something after all!

In the meantime, feel free to keep poking from your side. You might end up with better/different data that we might combine in the end and get better result
