    If you know what's happening to the ground temperatures in DOE-2,
    you should then know that they are calculated by a sine-curve
    equation developed by Tamami Kusuda in the early 1980's that takes
    up only 10 lines of code in the DOE-2 weather packer, using default
    values for soil diffusivity and ignoring the effects of  water
    table, surface evapotranspiration, or geothermal anomalies.  In
    other words, these ground temperatures are extremely approximate.<br>
