Daily snow temperature profile plots. Temperatures are measured at 10 cm vertical resolution
by stainless-steel clad PRTs. The spacing is maintained by a stout wooden dowel. Over time the
dowel and PRTs bury, so the array is initially placed above the surface. The position of the
snow surface must be derived from Fourier or Laplace analysis of the buried sensors, and turbulent
diffusion analysis of the above surface sensors.
Two separate arrays are used with overlap at the top of one to the bottom of the other. Over time the lower
array is discarded and a new array is deployed.

Times are in GMT: Halley is at 76S 26W. Text data are 6 + 21 + 21 columns:
Time (yy mm dd hh mm ss)
th(1), th(2),...,th(21) for array #1
th(1), th(2),...,th(21) for array #2
Note that array # 1 is not necessary the lower array.
Date / time stamps are the mean of the ten minute averaging period.
