I have released a new version of the Unhiding The Decline climate graphing software. Download UNHIDING.zip from this link and unzip it.
Put the UNHIDING.zip file somewhere in your filesystem where you want to extract it.
After extracting, navigate to the ghcnd_hcn directory
Type cmd in the Windows Explorer address bar
That will open up a Windows command prompt in the current directory.
Type in ghcn.exe US.list states=ILIN summer
In a few minutes this graph should pop up, showing average summer maximum temperatures at all Illinois and Indiana United States Historical Climatology Network Stations.
There are a lot of features you can access, and I will probably make video showing some of them. The source code is in the same directory in the file ghcn.py. If you have a python3 environment on any platform, you might be able to run the command as :
python3 ghcn.py US.list states=ILIN summer
