I'm looking for average/yearly global rainfall and average/yearly temperature data that can be synced up to terrain and elevation maps I currently have in QGIS. High accuracy is not crucial (any year, or even multi-year would be fine), but I want something a little better than the tiny maps I've found online. QGIS seems to like tif files but I've been unable to locate any with rainfall or temp.

I actually need these for a non-GIS related project (not scientific either), but it seems like I can use QGIS to ensure the maps are overlaid accurately, and to convert to greyscale values. (So if there are any large enough png or even jpg images which could be converted to greyscale, that would work too.)

Attached is an example (with elevation data) of what I want for the final product, scaled down drastically. The actual size is a 22,000 by 8,000 png with a transparent background (black would work too).

Edit - I'd also be willing to try and generate something using just numeric data, if it's available anywhere...

I guess there just isn't easily discoverable data available like this.

Found something which looks usable for precipitation at least... although probably won't be QGIS friendly so I'll have to line things up manually I guess. Crap quality jpg but may work for casual purposes.

    It looks like you can download the source data for that map: worldclim.org/version2 and worldclim.org/version1

  • this is not an answer...where did you find the data?

  • It's not a good one, but it's all I could find. Should I delete it?

  • Crawling through here again, to elaborate a little on "where did you find the data" - I'm pretty sure I DIDN'T find the data, it was literally just that jpg! :( If I had a better link at the time I'm sure I'd have posted it. @albert

I see that CSk mentioned worldclim.org already. Worth checking the list here: Free GIS Data – Weather and Climate Data https://gisresources.com/weather-climate/
