Station Visit Thursday, 7/13/95
LIGHTNING SPIKE INSTALLED:
On 5-m tower configuration, we fixed and added the lightning spike to the tower to get back to a better configuration for protecting the tower.
ANEMOMETER INSTALLED:
The rebuilt anemometer was put back on the station, however because of a storm hitting the area, we were unable to align the direction properly and it is now
only about +/- 30-degrees accuracy until we can put the full tower assembly back up.
RAD LEVEL:
The RNET sensor was leveled during the setup on 7/8.

- 43: PAM1/1 Sat 22-Jul-1995 18:15:30 GMT Moved RF antenna, fixed MRI
Visited the PAM1 site around 1210 edt today. Lowered tower to move RF
antenna from about 105 deg to 120 deg in an attempt to improve
communications to the PAM base. Sonic level looks very good:
alev = 0.01 deg, blev = 0.02 deg
Fixed MRI rain gauge by reattaching lower red wire to the (hopefully)
appropriate point.
Site is overall pretty dry, but there is some standing water NE of the
tower.
- 48: PAM1/1 Sun 23-Jul-1995 13:43:55 GMT sonic blevel, PAM#1
The sonic blevel on station #1 has a very clear positive correlation
with temperature.
7/24/95
Talked with Gary Zimmerman today. He notes that the two level sensors
are actually at 45 deg to the sonic u and v axes. Since these two
signals are combined (added and subtracted) to produce the alev and
blev outputs, there a very few components that are not common to both
axes. Gary suggests removing the small daughter board that does the
addition and subtraction to determine whether that changes the output
dependence on temperature.
- 56: PAM1/1 Mon 24-Jul-1995 16:37:38 GMT Propvane angle, site photos, site location, hygrothermometer
I shot the prop-vane boom angle this morning at 127 deg 43' 5". The
angle that Matt used when we moved the anemometer from 5m to 10m
was 133 deg.
I then took site photos with a 28 mm lens, starting at N and
rotating around clockwise. I also took 5 photos at 45 deg increments,
starting at 90 deg to the sonic boom, going to parallel to the
boom, and to 180 deg from the first photo.
I then measured the site location relative to local features. The
site is 245 paces south of the section line and 115 paces west of
a large grove of trees. Each of my paces is roughly 3 ft.
I measured the site location with GPS and found the following
coordinates:
28 deg, 39.27' N
81 deg, 04.41' W
These are in good agreement with my previous measurements on July 11.
I found the inner metal radiation shield of the hygrothermometer on the
ground below the sensor. I was able to reinsert the shield but, in
order for it to not fall out again, I had to put it in so that the
flare at the bottow was flush with the bottom of the plastic
multi-plate shield.

- 79: PAM1/1 Thu 03-Aug-1995 13:47:32 GMT Turned sonic back on
On the afternoon of Tuesday, August 1, John turned off the power on the
sonic anemometer in preparation for hurricane Erin.
Steve Semmer and I visited the site around mid day on Wednesday, August
2, and found about 1/4" of water in the bottom of the sonic electronics
box. I dried up this water, but did left the sonic off to hopefully
dry out. The site is very wet with a lot of scattered standing water.
I revisited the site this morning and dried out a little bit of water in
the bottom of the sonic electronics. After checking the connectors for
water and finding none, I turned the sonic back on.
John asked me to also check the Free Wave radio status. I found the
red light blinking and the green light on.

Work at PAM 1 included fixing solar panel cables for

Unfortunately the clock time did not improve. I may have read
the GPS receiver incorrectly. The transmit time is still within
