Warm, calm with scattered cirrus. Extra soundings around morning transition, plus regular soundings (0Z, 3Z, 6Z, 9Z, 12Z, 18Z). Missing data on some soundings due to unknown reasons, eg, 3Z lost at 400mb, 6Z had data gap 960-925mb, 12Z lost GPS between 800m and 6km. Interestingly Notre Dame reported missing GPS from their iMet sondes this morning as well.
Vanda visited today, attending the 12Z sounding and doing a tour of various sites. Afternoon science meeting after the regular briefing.
