Hi All, Got a request regd need to simplify this IMD grid data fetching process for folks, and that gave me impetus to complete setting up a website where individual location + year data can be downloaded as simple flat CSV (which opens in Excel / LibreOffice Calc).
So here it is: *https://server.nikhilvj.co.in/imd_data/ <https://server.nikhilvj.co.in/imd_data/>* There's a map and year selector to help choose, after that a link is generated for downloading. Open that in browser or do wget/curl on commandline, and it'll download a CSV with proper naming. Sample link: https://server.nikhilvj.co.in/imd_data/API/fetchData?year=2010&lat=25.25&lon=76.25&which=all You are *encouraged to scrape* : use the format above to compose your own link. (Hint: Excel formulas like: =A2&B2&"?year="&C2 are perfect for this) With a caveat: Given that it's not some fancy server that can take huge loads, there's a cruel and harsh rate limiter in place which will allow only 1 hit per 10 secs per IP address for anonymous users. If you want to bypass that, there's an email-otp login process given which will add a token and let you do 5 hits per second, and that won't be restricted by IP address. This would be useful in institutions where multiple users on the same network may want to fetch data at the same time. ex: a school/college hands-on session in climate data visualization where the host as usual forgets to pre-download the data So you can scrape and I can keep my server from crashing - both sides win. Source code is at https://github.com/answerquest/IMD-grid-data-work (see imd_data_api folder) -- Cheers, Nikhil VJ https://nikhilvj.co.in On Wed, Oct 12, 2022 at 8:30 AM Nikhil VJ <nikhil...@gmail.com> wrote: > Hi Pankaj, > > The place initially referred to is archival data - by definition it's > historic and not realtime. > What I do see on https://imdpune.gov.in/lrfindex.php is "Gridded Data > Real Time" -> you might want to explore that. > Over there, Daily 0.5x0.5 grid temp data links are there. > You can select a single date there and download the file. > > I don't know right now how to open it, though. imdlib library that I've > used - I didn't see anything about daily data. > Here's its documentation: > https://imdlib.readthedocs.io/en/latest/Usage.html > > I've posted a query about it in the lib's github : > https://github.com/iamsaswata/imdlib/issues/17 , let's see if the author > responds.
