Thanks for this Ujaval, only thing is that I'm doing this for a media publication, so it's important to use the same long-period averages the IMD uses. If it was for my personal projects, I wouldn't have minded calculating them myself, but have to go by official figures now :(

Let me know if you will be able to get something. On Tue, 20 Jun 2023 at 4:11 PM, Shijith Kunhitty <shij...@gmail.com> wrote: This Q. is for people who work with weather data. I'm trying to do something related to the monsoon, but can't find what I'm looking for. Now monsoons are considered normal or not by comparing it with the average monsoon rainfall over a 50 year period 1971-2020, which is called the long-period average (LPA). Tried looking for state-wise LPAs for 1971-2020 on the IMD website, but couldn't find it. The closest I got was this image <https://mausam.imd.gov.in/Rainfall/Normal_Rainfall_Maps/Monsoon/Monsoon_STATE_NORMAL_RAINFALLMAP_COUNTRY_INDIA_c.JPG> from the IMD but it's for the period 1951-2000. If someone could give me some leads on where to find more recent state-wise LPAs, I'd really appreciate it. -shijith -- Datameet is a community of Data Science enthusiasts in India.
