I would like to ask if there is a homepage where I can get weather radar data for Europe territory for free. I have looked in the internet, but can't find them. I will be very glad if someone can help me. (It would be ideal to get the rainfall or precipitation data for Latvia.)
Weather radar data specific to Latvia can be found using NOAA's Radar Data tool. Just enter "Republic of Latvia" in the search box and you're off and running.
There are a large number of datasets covering international areas at the U.S. National Oceanographic and Atmospheric Administration (NOAA), which maps some of the global daily indicators. The Global Historical Climatology Network-Daily (GHCN-D) is the data you are seeking.
International indicators of climate change and data collected from many organizations are available as well.
