Radiation stand at site 09: CR23x of University of Basel : Power up, Time set (GPS).

From 07-22 (around 16:00 PMT) to 07-24 (10:00 PMT): Work at radiation stand site 09 University of Basel. Cables and ladder may have disturbed measurements of NCAR. 

Radiation Setup University of Basel:

> CM 21 950239 upward on block 2 E.
> CM 11 ?????? downward on block 2 E.
> Pyrg. PIR/WRC upward on block 2 W.
> Pyrg. PIR/WRC downward on block 2 W.
> CM 21 910004 upward N side of darkhorse, W of block 2.
> CNR 1 ?????? upward/downward S side of darkhorse, W of block 
..

7-23 around 17:00 PMT Soil sensors installed.

Soil Setup University of Basel:

> HFP 656338 / BT 10 : 4th furrow S of darkhorse feet.
> HFP 656440 / BT 08 : 1st furrow S of darkhorse feet.
> HFP 65628  / BT 15 : 2nd ridge S of darkhorse feet, S-slope.

7-25-00 17:30 GMT: cleaning of all radiometer domes at stand site 09. check of level. All ok, except NCAR upward looking pyrradiometer is only a little bit out of center. nothing adjusted. cr23x uni basel: time incorrect.

NUW - 5	
Placed at site 9 showed some unusual spikes in the T(?) values. 
It was replaced by an ATI sonic.
	
The tests done at the PAM Base raised doubts in the proper operation of one of 
the transducers. After the first set of tests the sonic quit working at all and it has been found that it was draining to much current.

This unit has been sent to ATI for further analysis.

7-30 16:00 - 16:15 GMT Cleaning of all domes at radiation stand site 09. Dome of Q*7 of NCAR is dirty, especially at lower parts. probably due to spraying. Completely cleaning was not possible. Time Uni Bsel OK. Leveling of all instruments OK.

8-1-00 18:38-19:00 GMT:
Radiation site 09: Leveling OK. Domes OK. No cleaning.

Wed 8/2
Dave Vaughn has been given a 220VAC tap on the 2.5kVA transformer
serving site-9/Marigold.  He provided a step-down transformers
and the Romex.
He had attempted to run it using 2 solar panels and 5 batteries
without really knowing what his load actually is.
At the moment he reports 3A at 110VAC for 3 separate pumps;
presumably not all on the same leg.  He has not finished configuring
his equipment yet.

NUW3 at s9 died yesterday evening.  With rserial, it seemed to have the
wrong baud rate.  I used the test cable to set it back to sane mode,
and then reconnected with the normal cable.  All appears to be normal,
and it appears to have the correct rotation matrix as well.

I don't know why this problem occurred in the first place.

To reduce some of our power problems, we've rerouted power to have all of
s9 connected directly to the second 220VAC outlet on the PAM base, and
not to the 8 KVA transformer near s8.  Our load should now be:

s7: 8A @ 220VAC operating, 13+A when A/C starts.  On 30A circuit shared with
    s8, through 15A breaker at 8KVA xfrmr

s8: 3A @ 220VAC.  On 30A circuit shared with s7, through 20?A breaker at 8KVA
    xfrmr

s9: 4?A @220VAC.  On 20A circuit also supplying s10.

s10: ~3A @220VAC.

P.S. Outages and brownouts throughout the Calif. power grid have made 
national news over the last few days associated with high temperatures.
Thus, some of our problems may be outside our control (though the UPS
in the base hasn't shown any alarms.)

PPS: I accidentally shutdown the UPS simply by connecting the Toughbook
to the DB9 connector on the back.  This shouldn't have happened!

The UW sonic has been reporting bad V winds and has
'unusual' tilt plot.
The sensor, including the Krypton was taken down
and zeroed in the lab.
Down: ~18:15-19:40
Hopefully the data will be improved now.

The sonic at station 9 has been questionable. John and
I replaced it with the repaired unit from ATI only to
find out the repaired unit does not work at all. So
we re-zeroed the questionable unit and set it back out
at station 9. The sonic still appears to have problems.
The u and w components are questionable.
This work took place between 17:00 and 22:00 GMT.

After talking with Steve O. last night, I have changed
the UW at station 9 to operate in an orthogonal mode. We
may be able to identify a bad set of transducers.
This change was made about 5 minutes ago.

Based on the test of the individual sonic axis, the
u axis is noisy compared to v and w. I will take the sonic
down and check the solder joints on the transducer wires
attached to the electronics board.

The sonic at 9 has gone from questionable to dead.
The solder connections looked ok. When I tried to
re-zero it, the distances were bogus for all 3 axis.

Summary of TU Dresden measurements at Swiss-Site (see also Vogt and Christen)

Data sampling from the Campbell logger was done at every field trip, data are almost continuous from July 31 to today

July 30, 2000	instruments added to station 9
		METEK USA1, LICOR 7500 (open path) at 6m above the ridge 
		(tower B, above Solent R2), additional miscallaneous 
		(TCs, HMP35)
		Data transfer to Swiss computer (raw data 20 Hz)
		Fluxes on-line via CSI CR10X (8 Hz)
		METEK running, but produces 'invalid data
		CR10X started on PST
		LICOR values mV=mmol/m3
July 31, 2000	METEK path lengths measured at tower (roughly with ruler),
		data o.k., temperature about 6 C too low, uvw evt. also affected
		no re-calibration done, should be corrceted later
		19.40 PST time changed to 2.40 GMT
August 1, 2000	several tests performed with METEK for band-filter (esp. 40 Hz
		measurements), not succeeded returned to 20 Hz raw data
		21,48 GMT: LICOR chnaged to mmol CO2/m3 = 15/5000 mV + 10,			mmol H2O/m3 = 1/5 mV + 250 (same as Foken)
August 2, 2000	Campbell logger connected to 12V DC (was running on back-up batt			eries only), power down at 17.30 GMT
August 3, 2000	o.k.
August 4, 2000	o.k.
August 5, 2000	o.k.
August 7, 2000	o.k.
August 9, 2000	o.k.
August 10, 2000	o.k., common effort to measure canopy height across field 
		(see Vogt)
August 11, 2000 o.k., 
		18.15 GMT :LICOR cleaned (window indicator went down from 62 
		to 59%)

The sonic and fast Q are running again at site 9.
The sonic came back from ATI. When I first powered it up
it did not work. Playing with the board I got it
running. Be warn it may go down!

In getting the UW sonic fixed by ati, all our settings were lost, so we've
been operating it wrong since it was installed yesterday.

I just changed:
- set the serial number from unassigned to nuw5 (I think this is right).
- shadow correction turned off (was using 0.84/0.16)
- rotation matrix changed from ATI's default to that from the 6/9/2000
  measurements.

Thus, it will be difficult, if not impossible, to recover data from the
last 28 hours or so.
