Clear early, but scattered clouds developed and gradually thickened.  Winds were light and variable during the morning, then the usual southerly picked up during the afternoon.

Discovered that the MISS profiler eastward as well as the northward winds were reversed overnight, so I must have reversed the east-west beam codes yesterday instead of the north-south.  Fixed the problem and from about 1620 UT the MISS winds now appear correct.

The students launched two radiosondes, 10am and 3pm PDT as usual.  No problems apart from the surface met data is not appearing on the sounding software display but that does seem to be making it into the data files.  Carol reported that the sounding messages are successfully transferring to the GTS.  Matt arrived last night and joined the soundings today to get a catch-up on procedures.  These are mostly the same as previous projects, except that here we are using the iMet balloon enclosure (basically a large fabric tub that we inflate the balloon in as a test for possible use in Hydrogen balloons).

The. ISFS group moved the tall tower today.  I had been using it as a hard target for calibrating the orientation of the Windcube lidar.  I did one last set of scans this morning before they moved it, now it is beyond the ISFS tower array around 2 km to the east.

Cleared off the glass windows of all three wind lidars, the ceilometer, and the Hukseflux NR01 radiometer (around 23 UT).  The Windcube washer water tank was almost empty and using water faster than expected so we will have to monitor that closely.  Made minor adjustments to the Windcube scan strategy, the MISS height range, and the UVA Halo orientation (it was pointed about 1 deg west of north).  Also tied down that lidar in case of high winds, backed up data, and tidied up around the site.   The Windcube data hasn't been transferring to the Data Manager computer for a couple of days, Isabel is investigating.

Visited Shane and Bruce and got a tour of the REAEL lidar container - impressive.
