2003 Snow Temperature Profile Data for Halley

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. If you wish to use the images or would like the original data, please contact Phil Anderson
