  Preparing condensation nucleus counter launch, Aug. 30, 2004. Note parachute, GPS, mast (for finding it later), and the snow falling.

  Lou holding the balloon for the condensation counter launch.  This balloon is much bigger than the one we use for the ozonesonde.

  Jen testing the ozonesonde in the wind and snow, September 7, 2004.

  The wind really picked up.

   And then the blowing snow, and you could hardly see Scott's Discovery hut.
