If you read the NASA page, they explicitly cite GHCNd, a raw surface temperature and precipitation dataset that goes back quite far. There's many other similar datasets you can find if you're willing to look.
Check out the readme for the csv format description, and /by-year for the raw rows:
picked four stations at random[0] and it's just precip numbers, no temps, no humidity, no insolation, etc.
are you sure you linked what you think you linked?
[0] /by-station and then unclutched my scroll wheel and spun it for arbitrary amount of time, re-engaged clutch and clicked what was under the cursor. repeated 3 more times. i did a fifth, where the one i was looking at was identical to the fourth one, but had a 1 in the least significant portion of the station ID instead of a 4, in case it was like, "4" is precip, "1" is temps, and i happened to click "4" 4 times in a row.
