<p class="MsoNormal" style="margin-bottom:12.0pt">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.<br>
