Level electronics mounted
About 1100 local, the level electronics were mounted and connected. Initial
readings showed about +/-.3 degree variations from wind shaking (~6 m/s).
I will work on the analog output from the display unit so we can look at this
in more detail. (Only one axis works on the display unit now.)
Initial readings were in range of the levels, on the order of 1 degree, so overall
alignment appears okay.

From 10 am until 1:30 pm, Gerry Albright and Tom Horst
used the Nikon theodolite to measure the azimuths of the
prop-vanes and sonics. The theodolite was oriented
with a compass to true north, using a declination of
13 deg E. The orientations of the anemometers were
determined by setting up the theodolite about 150 m
in front of the anemometer and moving it until the
line of sight coincided with the anemometer orientation.
The prop-vane alignments are the orientation of their
booms, the ATI sonic alignment is that of the u axis,
and the UW sonic alignment is that of the boom.

The anemometer at 15 meters was removed on the 19th in the morning. Upon examination,
a broken wire existed in the cable to the direction encoder. Why this had anything to do
with the wind speed going bad is a mystery. Once repaired, the sensor was working ok.

Favorable winds called for

getting the instrument running. I would
recommend after turning everything on and
confirming things are working ok in the base
that the bridge adjustment be reset. This
way the electronics has a chance to stablize.
I was not successful in running
Steve's 'ql.sh' routine to verify data on tape.
The program would boom out with a
"log10: SING error" followed by a
"ERROR 5 in AGNUMB - EXPONENT TOO LARGE".
I went ahead and started recording on tape
anyway.
When starting a new tape, the first
7 or 8 messages from daisy seem to get
written to tape; ie; the light blinks.
After that there is a 10 to 15 second delay
before things start going again. I assume
it has something to do with the exabyte
wanting to put a header file at the
beginning of tape. Maybe this is why S.O.'s
program failed. I'll talk to Charlie about
it.

is obvious. Tom suggests that if the winds are light
tomorrow that we put the zero box on all of the

Because the prop which was at 7m (W004) has been acting up (and because
I broke it's propeller), it has been moved to 1m. The prop which was at
1m (W001?) has been moved up to 7m.
In addition, it was found that the bearings on W003 (4m) are rough and
may have contributed to the speed drop-outs. The spare prop (W007?) will
be put in its place. Thus, in a few minutes the arrangement should be:
15 m W006
10 m W005
7 m W001
4 m W007
2 m W002
1 m W004
Since the alignment of the 1 m and 7 m booms differed by only 30 seconds
of arc according to the theodolite measurements, the direction was not
reset for W001.

Playing around with v.ati.7m triggering
The received wave on VR2 (on the top of the board) is having trouble. There are a weak
positive-going, a rather strong negative-going, and a strong positive-going half cycles.
Currently, it is triggering on the strong +, and appears to have a wind speed bias of
20 m/s. The best point appears to be the strong -, but the sonic would have to be rezeroed,
and the wind speed is now strong enough (6 m/s) to make that difficult). I will now reset
it to the weak + and hope the signal improves.
The signal got better, but didn't appear to be a function of triggering. Probably,
triggering on the strong + was best, since the wind values appear to be a bit low.
The winds are too strong to be able to detect the change of one wave ~= 1 m/s. Zero
should be checked the next time winds die down.

After zeroing 13m.ati, the w component improved
somewhat, but still has a noticeable bias of approx
-0.5 m/s. Since it seems that this is not the
result of a true zero bias offset (we put the
zero wind box on the w-axis twice and got the
identically same offset value of 0.27 m/s, so we
our correction was right) the conclusion is that
it must be coming from somewhere else. Could
the sonic have a big enough tilt to give this
big of an offset? Seems unlikely.
