I have now published the data for the forest and you can find it here Marcell Experimental Forest .  Operated by the USDA Forest Service, this location serves as the Northern Research Station.  This data supports and validates the data from the St. Paul Climate Observatory and demonstrates the heat gain associated with the conversion of land to human habitat.  I will not be working on the Swan Lake data that gives 3 different sources of information, and all 3 supporting each other in heat gain and time frames.

With the Forest Data now available this has allowed us to review a 3rd and unique environment but depths are limited.  I now have 3 locations with multiple data sets for various environments, all in Minnesota.  The St. Paul U of M Campus Climate Observatory that measures down to 1,280cm since 1963, Swan Lake down to 300cm since  1997 to 2014, and now the Marcell Experimental Forest just north of Grand Rapids from 1990 through 2016 that will be coming soon.  Swan Lake and the U of M were cross examined and demonstrated the same alterations, specifically the days of overturn that occurred during the year.  There is a difference between depths of measurements, 150cm compared to 160cm, and 300cm to 320cm, a 10cm greater depth that would result in 7 additional days at Swan Lake above the Climate Observatory. and both are located very close in latitude.  The fall of 2005 and spring of 2006 was not available.
