For a while now I have been harvesting data from my weather station and am now analysing it for trends etc.
I wish to compare what I calculate with typical "averages" for my area.
I live in Guiseley near Leeds and found data on the Met Office website for a weather station in Bingley. I also had looked at other "sources", one being Weatherspark for Leeds/Bradford Airport.
Whereas the temperature data agrees between the two, the rainfall does not.
Met office Bingley, 1991-2020, average annual rainfall is 1057mm pa.
Weatherspark LBA, 1980-1016, average annual rainfall is 581 mm pa.
In fact other Met Office stations also report rainfall averages twice or more that the "Weatherspark" and similar websites.
Too large a difference, what am I missing?
Yes, I agree that both sources of errors do propably exist but I would have thought that the discrepancy would be far less than 50% / 100% that I find. Like you, my feeling is, until I understand their data sources better, to go with the Met Office data.....we do get a lot of rain here! Thanks
