The download of the onboard pocketec data to exthd7 from West was started as of ~1610LT.

Based on data storage levels on exthd7 and exthd9 the data from Central tomorrow may need to be placed on exthd9.

The T/RH sensor at West 30 m became uni-valued at approximately noon local 26 Apr 2006. With the help of S. Oncley it was master restarted electronically at ~ 11am local 27 Apr (through rserial) to its former level of performance.

~10:45PDT soil sample taken
Some pebbles in 0-3cm, nothing in 3-6.  Rain yesterday, so good opportunity.

0-3cm	153.8-53.7 = 100.1gm
	b1	28.0	27.7
	b2	32.0	31.6
	b3	26.6	26.1


3-6cm	136.5-27.0 = 109.5gm
	c1	35.7	34.5
	c2	36.7	35.5
	c3	36.8	36.8



10:20PDT Trime Brad took these readings:

2	5.8
3	5.9
4	4.5
5	4.5
6	4.6
7	5.4
8	5.5
9	5.4


All 3 sets of 3 readings had good penetration at 45-deg angle in the vicinity
of the station soil sensors.   #1-3 were in bare ground east of sensors,
#4-6 'mixed' west of sensors, #7-9 bare, south of sensors.

Cleaned 5m,30m with methyl alcohol

The laser for the 9012 particulate counter is bad and needs to be returned
to the factory for repair.

This was determined after discussion with Robert Falbo who is the expert on
the sensor.   He suggested two tests (Note it is safe to work on it because
the laser is self contained.

1) check exhaust flow.

The flow goes through the laser first, through some filters, pump, and flow
meters eventually to exhaust which is by the needle valve / nipple mounted on
the pump.  This needs to be roughly 3liters/min.
This test indicated that the pump is working.
The pump it is driven off a PWM technique which ramps the speed up
or down depending upon feedback from the flow-meter and counter.  This is why
it sounds as if the pump starts up slowly and eventually kicks in.  That had
fooled me into suspecting a clog or bad pump.

2) check current-shunt voltage for the laser.

The laser's health is monitored across TP1 (on the small 'perpendicular' pcb
attached to the end of the laser, and to TP3 (ground, on the main laser
electronics board).  These test points can be identified by the red and black
insulators around them respectively.
The correct voltage should be ~800mV; anything above 1V indicates a bad laser.
With this unit, the voltage was 1.6 dropping to 1.25 as the pump ramped up.
Robert confirmed it is bad and gave us a return authorization #

The aerosol particulate counter has been reporting bad data since
the 4/13.   Values now are almost all zeroes, with some integer values.

Tech support from MetOne sent the manual, which really doesn't say
much, and the windows configuration/monitor software which I installed
on the panasonic.  At the site, this software failed to communicate
with the counter even though procomm was seeing the raw messages.  At
one point I did manage to grab it's help printout during startup:
Tomorrow we'll bring the sensor down to the base

20Apr06, ~9:15PDT
Removed aerosol from tower.
At the base it appears to work, the pump starts slowly, but runs. It could
be that the pump, or filters are clogged because of the slow startup.
Other attempts to communicate with it via 'particomm' software still failed.

16:23PDT soil sample taken
Yuck, very dry and lots of gravel.  The 0-3cm had a large 'rock' in it.

0-3cm	169.7-45.1 = 124.6gm
	b1	30.6	30.2 = 0.4
	b2	21.5	21.2 = 0.3

1,2 didn't have 100% penetration, with ~3/4" of the top exposed.
3,4 was in a more open area, and had the same problem as above except I
    'cheated' and moved a bit of gravel around the top.
5,6 had good penetration and was closer to a bunch of grass, ~8" away
    with the 45-deg 'slant' toward it.

18Apr06, 15:50-15:55

Cleaned all domes.  Absolutely no evidence of dirt.

Adjusted level on Rnet.
tilted it 'up' from a sag to the south that had the bubble outside
of the target but not pegged.

18Apr06 15:05-15:15

Installed new charge-control-monitor board to get status values.

Gordon's xml worked perfectly and the plots are now available.

TP01 wiring harness swapped in logger.
The 'existing' harness had a problem with the +10V regulator output
needed for the heater.  I confirmed that the spare worked in the lab by
tying the '12Sw.Control' line too +5 and observed the 10V on pin-8.  At
west the same test failed.
Speculation is that the outage since 31Mar06 may be fixed.
It's possible that when the Xbee radio was installed in place of the Xstream
that the flimsy regulator wiring in this harness may have broken or
become intermittent.  We'll see....



Poulos, Militzer - West site visit 1600 LT Apr 17
Last night: 17Apr06
I beeped the wiring to confirm continuity as shown below and tried checking
the output of the regulator but that proved very strange after tying the
supply into +12: I could have sworn I saw 3.5V on Analog Ground....eeek!
The wiring of TP01 inside the logger is:
CR10	Color	Bulkhead Amp-9
4H	White		1
4L	Green		4

I am investigating the missing logger data reported on the Splus plots.
It appears that the data archive is complete, while the Splus file is
missing some data.

(P.S. This problem appears to be "fixed" by re-running stat_proc.)

Here is data from west logger as seen by Splus

kh2o s/n at 30 m = 1258

The Campbell data loggers at south and west have been losing data intermittently
which Steve suspects may be due to 915 MHz interference.
He removed the logger at west around 11:45 PST to replace the MaxStream radio 
with a Zigbee radio.

UPDATE:
   Went to re-install logger at west at about 16:00. For some unknown reason the cr10 lost its program. Will fix tomorrow.


Update 4/1/06:  Steve went to reprogram logger and after switching cables to do this, it started on its own, so apparently did not lose its program as thought.

Created a new directory on /mnt/exthd8/projects/TREX called local.
Downloaded data with, e.g.
scp root@west:/var/tmp/usb/TREX/west_20060326_000000.dat 
                                              /mnt/exthd8/projects/TREX/local

Since we saw cows yesterday near the west tower, I put a fresh battery on the
electric.fence.

Steve cleaned the KH2O at west; on tower from 1258 - 1318.

Cows in vicinity.  Need to activate the fence.

March 23: Tom at west site for maintenance; arrived ~ 1415 pst

Guywire tensions (lbs)
	SE	NE	W
1	450	360	375
2	300	290	310
3	385	300	280
4	340	295	290

Cleaned radiometers with methanol 14:38
Replace fuse on serial channel 14 to restart aerosol spectrometer.
Alone, so did not clean KH2O

- mounted MetOne aerosal counter at 15m (TRH is at 14.5m).  Returned at 14:30
to complete cabling
- took gravimetric soil sample.

Tom and Steve visited West tower after South tower.

Replaced TP01 power cable within logger.  Data look good at trailer.
Steve cleaned KH2O at 5 m and 30 m.  On tower from 11:05 PST until
11:25 PST.

Apparently, cleaning the 30 m KH2O decreased the output from 1.7 V to 0.8 V and decreased the 5 m output from 2.9 V to 1.5 V !!!

The wire from C7 to +12SW control never was installed in this logger.  Have
done that (and reseated the TP01 cable wires that we removed last night).
Will look at the data after a few hours and see if this works.

Connected the TPO1 that was originally installed, though the spare is still
in the ground.

Also removed the beacon control circuit for debugging.

Also gave a tour to one of the lidar ladies and took photos of the KingAir.

P.S. Didn't work.  Visited again about 18:00 (to replace the beacon circuit,
which now got it running) and found that the regulator ground pin had broken
off.  Have just fixed in the trailer (18:45) and will put back tomorrow.

Brad and Tom visited west site before noon on Monday Mar 13.  Brad and John 
returned in the evening to finish some tasks.

Brad and Tom took two new batteries to site; replaced auxillary battery;
later in day Brad and John replaced main battery (waited to change until 
had console to shut down system first).

Fixed beacon daylight sensor by squeezing terminal on red wire to fit more
tightly on pin.  Measured proper output voltage with sensor covered.
However, John reported that it was not working when they returned to the
site that evening.

Brad tripped on loose coil of wire between NIDS and logger wireless receiver.
Beeped out cable ok but connector broken on receiver end.  John and Brad 
replaced cable later in the evening(?)

Removed internal logger TP01 cable for check out at base.  Steve O. checked
regulator okay.  Brad and John replaced cable in the evening.
Connections:
White H7
Green L8

Visited west ~9:30-10:10.  

Tried to fix TP01 -- don't yet know if I did anything.  Only real change was
reseating +12 SW control wire.

Installed beacon controller, but didn't work.  Kept plugged into (unswitched)
aux2.

Cleaned radiometers, though somewhat cloudy.

popped in at west ~10:40 to install new TP01.  This should tell us if the
problems are with the sensor or logger.  If it works, I think I did a good
enough installation to use (somewhat moist soil), though it will take a bit
to settle in.

West visit ~1230-1330

- cleaned rads
- cleaned kryptons
- TRIME readings: 11.2/7.7/9.7%
- aux1 voltage 13.37V

Visited west site ~1800-1840 to restart the usb drive (which needed fsck).
Also repointed the parabolic antenna to South, since south beacon was visible.
Also checked guy wire tensions (see earlier log entry).

We just found that we can only run at 10BaseT speeds using the cabling that we
have to the AP24 at West.  Unfortunately, the AP24 appears to go to 100BaseT
on power-up.  Thus, we have a sequence:
- power-up AP24
- run the "Alico AP24 winbox" application on the Toughbook
- connect 192.168.12.43 (should be default)
- click on "ether1"
- set "10MBPS" and uncheck "Auto..." and "Full..." on "Ethernet" tab
- click on "Apply"
- ssh in from an outside machine (not necessarily easy)
- "reboot" nids

Since this is an unwieldy procedure, we need to either
- make a new cable (cat5 or cat6) that is long enough (18m)
- figure out how to save 10BaseT as an AP24 power-up default
