246°
GPS unit was set to true north.
Used the ACD/BEACHON Magellan GPS from the Chemistry trailer.
Should be confirmed due to potential operator error.
TRH015, installed at 2m on Aug 12 18:51 UTC also reports
incorrect humidities. Its cutoff is around 45%. Above 45%
the reported humidity is anti-correlated with the 4 other
sensors - looking more like a temperature.
In this plot, the night of Aug 11-12 shows the problem with
unit 013, and the next night shows the problem with 015:
replaced 2m TRH sensor at 11:50 MST on August 12

Old unit was TRH013, new is TRH015. Here's a data_dump:

RH at 2m went walkabout on about Jul 30 02:30 MDT.
After that time it disagrees with the other RH's above ~60%. This looks like what we
saw in ASP09.
This may have happened during a rain event - the sonic diagnostic
flags were high during that time.
The following dump of CSAT sonic parameters is from /var/log/isfs/manitou_BEACHON_SRM_csat3.log
on the data system. It was generated on Jul 17 when the data acquisition process was last started.
These serial numbers agree with Chris' sensor height blog entry.
