Do you know anywhere that has a dataset of Max dew point for each day? I know I can pull hourly observations but I have no clue how far back that goes and even so I don’t know enough coding to use Python to do it in any kind of efficient manner. 262,000 lines of observation isn’t handled well in excel or google sheets. You need store such data in a .txt file realistically and call it within python or Matlab or upload it to a different google service and use API to call it to run the statistics using python or some less well known languages. .
