[Equest-users] Ground temperatures

[Joe Huang]

In my opinion, the easiest way to get the ground temperatures would not be through DOE-2 
Hourly Reports, although I'm sure that can be done, but by reading them from the weather 
file using the WTHFMT2 utility program that converts the file from binary to text.  There 
are just 12 numbers for monthly ground temperatures, shown on line 2 of the *.FMT files.  
By the way, I think that DOE-2 does some smoothing or interpolation of the monthly ground 
temperatures; right now if you look at the hourly heat transfer through Underground walls 
or floors, you'll see a wierd staircase effect with the same load for a whole month, and 
then a jump to a different load the next month, etc.
