Two reports from Karnataka this week highlight that over half of the 6605 rain gauges in Karnataka are non-functional. Earlier we saw that IMD does not even report rainfall for at least 11 districts in Arunachal Pradesh alone, possibly since it does not have adequate number of rain gauges in those newly formed districts of Arunachal Pradesh. IMD’s Annual Report for 2025 says P 59): “IMD operates 1,008 Automatic Weather Stations (AWS), 1,382 Automatic Rain Gauge (ARG) stations, 200 Agro-AWS, 5 Automatic Snow Gauge (ASG) stations”. That comes to 2395 locations where rain or snow is measured by IMD, going by the Annual Report. IMD apparently uses rainfall data from other agencies, but their number is not given in the report. IMD also has a large number of manual rain gauges, but the IMD Annual Report does not provide those numbers.
