Hi,

I am doing a pollution analysis of certain cities in India. I would like to have weather data starting from Jan 2019 to April 2020. The analysis is being done to see the effect of weather elements on the concentration of various pollutants.

Can anybody recommend a source from where I can source the weather data??

Thank you.

Hi

This site has a lot of weather files http://climate.onebuilding.org/WMO_Region_2_Asia/IND_India/index.html

If you shorten the URL you can get anywhere in the world, I’m just sending you a link to go directly to India :slight_smile:

Edit: these may be older than what you want but maybe people have been uploading some? Otherwise I would contact universities or weather stations and ask if you can use their data. You’ll probably have to build the file yourself though

Hello @AnuragVerma
You can use dragon fly Amy generator to generate Actual mean weather file for a particular year.
You can download the data from here

Hi - I’m not sure if you’ve found the weather data you need but I’m currently testing out a weather data service per this post (Looking for Beta Testers for Weather Data Service). If you’d like to try it out, would appreciate any feedback.

Thanks,

Thanks Asisnath. I was able to find the data for Delhi for the year 2019. But, I can only get it in .csv format, and we know that the AMy generator needs .txt file. I was looking at an earlier post of yours where you encountered the same problem. But I still cannot seem to be able to download the weather data in .txt format.

This is the data: https://www.ncei.noaa.gov/access/search/data-search/global-hourly?stations=[42181099999,42182099999]

Thank you Ellika. I found some latest data, however, with less parameters as needed for energy simulation.

Thank Joseph! I am trying out the example on hydra for generating the EPW file.
