====== IOP - Summer 2004 ======
IOP flights at UND the dew point temperature was high compared to the measured air temperature.

===== Cause =====
Bad calibration information in the instrument from the Spring 2004 calibration.

===== Solution =====
Send the instrument in to get recalibrated. September 2, 2004 ground check by David Delene shown that the instrument was working a lot better. Comparison with dewpoint generator shown measured dewpoint of 9.6 C when a dewpoint of 10 C was generated. September 24, 2004 Test flight in Grand Forks shown TDL dewpoint less the air temperature during cloud sampling.
