I tried to compare the real-time world weather radar from Japan: https://sharaku.eorc.jaxa.jp/GSMaP/index.htm, to various different weather engine that I know. I am so disappointed that none of the well-known payware: REX, Active Sky Next, Opus can reflect the real world weather accurately, given that downloading free precipitation data is not a hard task. Is there something I missed, and do you know what product can get accurate REAL-TIME weather?
This is a good website for real weather checking too, aside from the japanese one: https://www.ventusky.com/?p=-76.7;-56.4;3&l=rain-1h&t=20190727/1800
