Tom Quirk has tested this assumption…

Weather Station Data: raw or adjusted?

In my post on the Mohonk Weather Station, the question came up about “raw” temperature data. Tom in Texas complained that he’d looked at data from the observer B91 forms and that it didn’t match what was posted in published data sets. Neither NOAA nor NASA serve weather station data “raw”. We’ve all seen examples…
