Hello, My name is Rajesh. I am a student of final year engineering from IIIT, Basar in Andhra Pradesh. On your portal, precipitation of Nizamabad district is available from the year 1901 to 2002 but, there is no information on the number of rain gauges data used year wise to calculate monthly and annual precipitation of that district as they are not constant. It would be really helpful if you can also give the number of self recording rain gauges out of total number.
