Blog from August, 2009

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.

T.2m replaced

Andy Turnipseed replaced the 2m TRH on Wednesday. So far so good.

RH.2m still bad

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

replaced 2m TRH sensor at 11:50 MST on August 12

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

RH.2m bad after Jul 30

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.

CSAT parameters

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.
