chescowx Posted January 2, 2020 Report Share Posted January 2, 2020 So in analyzing completed decade data in the Chester County PA data set we see the following highlighted Trends. The Decade of 2010-19 was the 4th straight decade with increasing temperatures - which followed 4 straight decades of decreasing temperatures. Sounds kind of cyclical! This decade was the warmest decade in the data set with the current decade outpacing the previous warm decade (1910-19) by an average of 0.22 degrees or an increase of 0.4% This was also the snowiest decade on record besting the previous all-time snowiest decade with an average of 45.5" of snow per year. This eclipses the previous snowiest decade of 1900-1909 by 0.4 inches or 0.8% increase from the previous snowiest decade. Interesting to note that the coldest decade 1970-79 recorded the least average snowfall while the warmest decade 2010-19 saw the most snow. What will the future changing climate bring us? 1 Quote Link to comment Share on other sites More sharing options...
Chubbs Posted January 2, 2020 Report Share Posted January 2, 2020 The early Coatesville data has been adjusted down about 1C or roughly 2F. https://data.giss.nasa.gov/gistemp/station_data_v4_globe/ Quote Link to comment Share on other sites More sharing options...

OK - but the instrumentation/shielding/data recording has changed multiple times since the early 1900s and you are including all of those changes plus the siting change in the data you report.

chescowx Posted January 2, 2020 Author Report Share Posted January 2, 2020 Those adjustments are pure fiction - stick with real data - no computer model adjustments - just ridiculous. Give some credit to the NWS Observers - do you wonder why the adjustment was made to warm the data? I am curious...do you know how much has the PHL airport data real obs vs been adjusted downward by NASA over the last 40 years to account for the heat island that is PHL?

Adjustments are made because of known changes in instrumentation, has nothing to do with the observer. The phl airport data has been adjusted to reduce warming just as expected (heat island correction occurs during homogenization). Quote Link to comment Share on other sites More sharing options...

By the way do you have the delta (actual degrees by decade) between the heat island daily climate data reported from PHL and the amount NASA has applied their calculation to adjust from actual (shown on the thermometer) to the new actual?

Its the difference between the two lines on the chart. The homogenization procedure compares the airport (or any other station) to the other sites in the region to identify and remove heat island or any other non-representative site trends. Its not magic - all well documented and standard. Anyone could duplicate or produce their own temperature record if they wanted to. 1 Quote Link to comment Share on other sites More sharing options...
Rainshadow Posted January 3, 2020 Report Share Posted January 3, 2020 Keep it local and keep government agencies or anyone else who has an opinion about climate that does not live in the local area out of it.
