Day 13 of the Perdigao IOP.   The weather was pleasant, with broken clouds and calm surface winds.

Four sondes launched at 00UT, 06UT, 12UT & 18UT. Two students from CU and one from Berkley arrived today. I did a first training session with the noon time launch.

Lou restarted the data manager at the ISS3 profiler site, the profiler computer had been operating through the entire DM issue.

The skew-T plots stopped showing up on the web site yesterday. Will look at it during the evening launch.

John arrived today, yeah.
