a gps survey was done at site 8 today at 17:45
the antennna altitude (bottom of the choke ring) is 102.0 cm above the port
on the barometer

Marigold (Station 8):   down from 22:10-17:20Z  (beginning 17:10,5/20 CDT)
A simple power cycle restarted it.

The Campbell Sonic hung last night.
Restarted the data output via simple "rserial marigold 206"
and issuing serial command.  In this case i used the 'P'
instead of the 'W' but it seemed to work just as well.

Down: 10:15Z, (5:15 CDT)
Up:   14:15Z, (9:15 CDT)

The sonic temperature from the Campbell has intermittent
spikes that do not look real. twh

Marigold apparently rebooted at 1648 GMT.

Installed the AIR bandpass on the ATI tower and the CSI Krypton
sensor on the Campbell tower this afternoon.  Each sensor was
installed underneath the sonic boom and "behind" the sonic.

Calibration for Krypton:
	Added file $ASTER/cal_files/krypton1089
	and edited $ASTER/projects/CASES97/ops1/prep.config
	for marigold 100 q_kh2o("krypton1089")  d=(h2o).csi
	and restarted the covars.
	NOTE in the krypton1089 file I put in the "Full Range"
	coefficients instead of the Dry or Wet linear range.
	...I presume that's correct?
	These coef. were found on the Campbell worksheets
	provided when the sensors were rented for this project.

Calibration for BPH with AIR fast trh:
	Steve edited $ASTER/projects/CASES97/ops1/prep.config
	for marigold 101 t_vaisala(-41.731524,20.5538,-0.006932) d=(t).bph.s8
	and marigold 102 h2o_vaisala(2.646416,17.16,0.519267,0.0,0.0) 
		d=(rh,h2o,rh2o).bph.s8
	and restarted covars on 5/12: 14Z

Ophir was down.  Upon arrival, numbers like 2032, 2000 were being provided.  To make sure it was up, recycled power, which naturally killed it.  After fumbling around and finding the ophir.c calib routine, which Gordon documented (thanks-G), determined that "a" return is the command to initiate 20hz output.  That worked and guess what, we began getting the same numbers once again!

Everest IRT note: IMHO the sensor is pointed such that it's looking at the sawhorse in enough of its field of view to where a close look at the data is warrented.

filled holes in freewave box with brass scrubbies - no evident problems
taped up cabpbell serial cable to small tower

The sonic had to have its data output restarted manually after the power
down/up.  This was done by an "rserial marigold 206", command to talk to
the sensor.  Typing a "w" started the data rolling again.

Cycled power on FreeWave RF modem and on marigold to re-establish
network connection.  Done around 1500 CDT.

marigold crashed about an hour ago, but restarted itself by the time Tom
and I made it out there to fix it.

I've just upped the power on the freewave to marigold from 6 to 8, since
we have been having trouble communicating with it today (40,000 lost samples
reported by marigold, only 20% packet reception logged by the freewave).

I wonder if some of the trees along the "line-of-sight" are degrading
the signal more now that they are beginning to leaf out?

We found a miswired cable by comparing the two serial ophir cables.
Both instruments are now running as they should.

We've isolated the problem with the OPHIR at #8 to the serial cable.
We've pulled the cable from #7 to allow us to compare the two.
Hopefully, both will be up soon.
