Occasional Thoughts on Climate Change

[chubbs]

NOAA is in complete agreement with the raw data when you keep the station population constant and separate out the major station moves. Per chart above there are only a handful of long-term climate stations in Chester County. Both West Chester and Coatesville moved from towns  to cooler rural locations and cooled by roughly 2F. It is easy to remove the station moves by plotting the before move  and after move data separately.  Before the moves West Chester and Coatesville are both about 2F warmer than NOAA.Not unexpected because these the town locations were warm sites, similar to Wilmington De. NOAA matches the year-to-year and long term trend of the before move data at both stations. After the stations moves, West Chester and Coatesville were more representative of the county close to NOAA . Like the before move data,  NOAA matches the long-term trend  and the year-to-year of the after move datra. The only exception is a warm spike at West Chester in the 1980s and 1990s. Which is clearly bad data.

Chesco's claim that NOAA doesn't match the raw data is a complete strawman. He's the one who doesn't match the raw data. Why should NOAA match his faulty analysis?

Here are the stations by year. What Chesco call's "Actual" is far from it. There is a big change in the station population from warm to cool, towns to rural, south and east to more centrally located, with more stations in the cooler north and west section. Most of the stations have short records and don't provide any climate info.

 

Fake and false Charlie there are actually only 6 stations currently north of 40.0 N and 14 stations in the warmer south and eastern sections!!

Here's another way of comparing  NOAA to the raw data. Easy to normalize the data using a common year, 1950 in this case. This removes differences between stations to better  isolate the long-term trend. Again NOAA and the raw data are in  complete agreement on the long-term trend, roughly 4F of warming in Chesco.

There were no stations in the northwest part of the county back in the day.

And how many stations are in the NW part of the county today vs. the South????

11 of the 17 current stations in the data set are in the warmer southern Chester County area below 40 degrees

The main point is that the stations have changed. Taking  a simple average skews the data. The 1900 station network (City Of Coatesville, Kennett Square borough, West Chester Borough, and Phoenixville) is completely different than  the current. Mainly towns in the early days. No towns now.

Most of those stations are giving you zero climate information because they don't have long records. Only Phoenixville has data before 2007.

As always Charlie you try to explain away factual data vs. recast adjusted data which is just never a good look....that said let's take your revisionist Cyclical Climate Denialism back over to the Chesco thread to better expose this alternate facts view you traffic in!! LOL!!
