Chester County PA - Analytical Battle of Actual vs. Altered Climate Data

"That is a clear sign of a major station change, probably at Morgantown." That would be incorrect Charlie no station changes took place at all during the period that temperatures were reported by the NWS Coop observer. There were some moves after those temperature obs ended and they moved to just precip and snow obs.

Raw data determines whether there was a station change not NCDC documentation, which can be incomplete. The 2F cooling of Morgantown relative to Coatesville is clearly a station change of some kind. The Morgantown site was didn't operate for 5 months in the summer of 1966, station changes in Chester County that I have investigated usually coincided with station shutdowns.
