Hello everyone,
This isn't really my area of expertise, so I am looking for a bit of guidance. I wish to estimate the temperature underground at a depth of 5ft. The climate is Saskatchewan (Canada) so it is covered with snow in the winter, and fairly hot in the summer. There is no tree coverage, only grass. The widest average temperature swings are from about -28C to +32C.
Currently, I'm attempting to apply the model described here: http://archive.nrc-cnrc.gc.ca/eng/ibp/irc/cbd/building-digest-180.html#archived
My results however are pretty questionable. I am using an average yearly temperature of 2.6C, and a thermal diffusivity of between .8 and .15. I've calculated that the temperature swings from -35C in the winter, to +42C in the summer, obviously this doesn't make a lot of sense. Can anyone point me in the right direction for estimating underground temperatures? The model doesn't need to be accurate either, +/- 10 degrees is pretty acceptable.
Thank you,
