Note: The balloon with which the first attempted launch was
made was not inflated enough (16 cu ft) and did not pick the radiosonde up off
the ground. As a result, the radiosonde was dragged on the ground a foot or so
and had to be launched with a second balloon (20 cu ft, ~4m/s ascent rate).
Hence the later launch time (22:17 UTC).
Light variable winds at the surface. Temperature follows the
dry adiabat until about 550mb. The
temperature continued to decrease with height. Fairly large dry layer between
600mb up until about 400mb. Humidity then increased significantly, indicating a
layer of moisture (perhaps ice clouds).
