<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
11.0pt;font-family:Arial;color:blue'>I had similar problem when I used that
method. I later decided to use average monthly soil surface temperature from
NASA Surface Meteorology and Solar Energy website, link below. I use type 54 weather
generator to generate the hourly values for one year from the monthly averages,
I compared the values of generated soil surface temperature with the ambient
temperature for the same location, the soil surface temperature is higher than
the ambient temperature in summer and lower than ambient temperature in winter,
which means that solar radiation have been accounted for in generating the
monthly soil surface temperature average.</span></font></p>
