I wanted to ask if there are any plans to connect with the GSMaP (precipitation data). Today the best way to access the data automatically is using google earth engine, and I believe that many users of sentinel hub will benefit precipitation data on a daily and hourly basis, as provided by GSMaP.
There is no (short-term) plan to connect to the GSMaP data.
That being said, eo-learn has recently implemented an EOTask to retrieve weather data from meteoblue service, as part of GEM project. You can find the MeteoblueRasterTask and MeteoblueVectorTask descriptions on read-the-docs.
