International Precipitation Radar

This contains various sets of precipitation radar estimates from different countries, initially the UK and Finland. The data has been optimized with icechunk. The data stored in each store is limited to what is outputted by the national weather services. In Finland's case, this data contains the hourly 1-hour, 12-hour, and 24-hour precipitation accumulations. For the UK, this contains the composite rain rate radar output.
