FAST Q status:
Output of sensor agrees with previous
plots at this time of day, ~12 gm/m^3.

4m KYPTON CALIBRATIONS:
The calibrations for the 4m Krypton
were added to the preprocess.config file.
We will need to make some changes to the calibration
software since the path length is different from the
10m unit.

H2O at 4m:
The 4m Krypton was added to the
network around 23:45 GMT. Signal output looks
low. Will need to monitor.

FAST T:
The uw tower was lowered to work on the 4m
sonic. While this was being done, the fast T sensor gains
were checked. Below is the results of that test.
sensor gain
uw.4m 5.1 +- .01
uw.10m 5.08 +- .02
ati.4m 5.1 +- .01

FAST Q:
The 10m krypton windows were cleaned while
the uw tower was down. There was no major change in its
output.

We'll (Tom and I) wander out to the masts and fix it if it looks safe.
(We have to go out anyway to do the noon-time chores.)

I climbed the tower (with Tom looking on). The old one was definately
broken.

We aren't going to climb for this one - its down for the rest of this IOP.

FAST T TRANSDUCER CHANGED
The UW tower was lowered and RAGWORT:101 fast T transducer was
changed and calibrated. The fast T transducer "ragwort:100"
was also calibrated. The values are as follows:
transducer 100 absolute temp = +.05
gain = 5.02 + - .02
transducer 101 absolute temp = +.06
gain = 5.025 + - .015
The gain readings were taken from a preprocess file, and
averaged over several readiings.

The uw tower is backup. Fast T units
look good.

VAISALA HUMIDITY at 4m UW:
Since the Krypton instruments are not agreeing
well with each other, the decision was made to add a third,
independent humidity sensor. One of the Vaisala units was
choosen (it had recently came back from the factory calibrated)
The unit was mounted at the 4m height coming off the west side of
the Krypton unit.
Below is information on channel assignment, gain/filter, etc.
The sensor was interfaced to ragwort.
The sample rate was set to 20.
