Chubbs Posted January 25, 2016 Report Share Posted January 25, 2016 Thanks! Here is the annual T data plotted. The unofficial data looks similar to the official. Do you know the sites? Quote Link to comment Share on other sites More sharing options...
BeerandWXTogether Posted January 25, 2016 Author Report Share Posted January 25, 2016 I believe the pre 1870 stuff is from Franklin Institute but not at the Parkway site where they are now. I believe it was somewhere around Center City. Quote Link to comment Share on other sites More sharing options...
