Complete yearly weather data

June 18, 2023 9:10 AM

I can find plenty of sites that list the average yearly rainfall in, for example Mérida, Mexico. What I can’t find is the actual data that was used to arrive at the average. I’m looking for a site with charts (or hopefully data files) that have the rainfall by year for the last 10-50 years. Can someone with better Google skills help me out?

Daily climatological records are available from the Global Historical Climatology Network. Merida Centro has 95% coverage for 1961-2000; Acanceh has 97% coverage for 1978-2008; Merida Santiago has 65% coverage for 1982-2013. I don't see any GHCNd stations in that area with precipitation inventory for the last ten years. But the raw CSVs for these three stations might still facilitate your research.

Best answer: Realized GHCN monthly might suffice for this question, checked the inventory, and realized Merida Aeroporto had daily data from 1973 to 2023 and monthly data back to 1921. That should be what you're looking for.
