weather: clear and cloudy today.  Clouds have been coming and going.  No wind  

System crashed sometime around 23:00 12/23 GMT.  Seems strange, the program windows go away (are gone), but the computer is still running.  Is this normal??  Restarted adam at 05:00 12/24 GMT, everything seems to be working fine.

weather: cloudy for most of the day, a few periods of clear.  Adam been working just fine.  Did data backup - apparently was problem with CD and then backup moved files so that they couldn't be found when retried.  Cleaned rime off of all TRH sensors at ~03:30 GMT.
System is working with the adam on the snow rather than on the tower mount. No glitches today.

The box temperature did not seem too warm - it certainly is warm around the heating plate, but the exhaust of the fan is < 30C.  I do not know where the T measurement is made - but, if it is on or near the heating plate I can understand the apparent elevated T.  Bottomline - the system is working and not steaming so I will leave it alone.

Steve and I set up the adam on the ground next to the tower after bringing it back to the lab and having it run.  We slowly connected everything - allowing time for failure between changes.  Right now it is completely connected and has been running for a while.  I need to check to see if the 22m fan is turned on.

• Previous - Next - Index

I had a major crash with the base computer. While
trying to create a backup data cd, the cdwriter locked
up. It was constantly sending an error message about
writing. So I kill the process. I then could not get the
cd to eject. While my next idea was to cycle power on it.
CRASH! The laptop went through a reboot then complained
about a system file error. So I was dead in the water.
Tried reaching Gordon but no luck. I tried the backup
hard disk but it is outdated. So I tried the other disk.
It provided some useful info about correcting the
corrupt file manually. So I did and it worked.

• Previous - Next - Index

On 11/26/00 from 1655 until 1710 LT I switched the NO sample inlet to the 22 M tube and attached a snow sampling inlet.  Sample snow a a variety of places.  [NO] in top layer of snow is 4-5 times higher than ambient (500 pptv vs 100 pptv).

56: temp_rh, Site , Sun 26-Nov-2000 14:57:20 NZDT, NEW TRH heights

• Previous - Next - Index

I remeasured the heights of the 3 lower sensors.
The measurement was made out at the inlet, not the
tower support. Based on these numbers, the true heights
of the upper sensors need to be reduced by ~20cm.
The reason for this is the snow level at the tower
was deeper due to wind effects. The .5m did not change
because I mounted it after the IC test.

52: adam_field_computer, Site , Sun 26-Nov-2000 11:45:36 NZDT, We are back on the air!

• Previous - Next - Index

The adam is back up and running. The problem
was power via the TRH fans. Would you believe
RF interference? That is the best guess. With
the long fan cables running up the tower, they
act like antennas. Everything worked ok during
the IC because those fan cables were at the ground.

The ADAM an the night outside on the deck.
There were 2 TRHs attached. It appeared to have no
problems. I had changed the muffin fan because it was

Will do some more testing on the deck before moving
out to the tower.

50: adam_field_computer, Site , Sat 25-Nov-2000 23:10:39 NZDT, ADAM is DOWN!

• Previous - Next - Index

As one can see in the data, ragwort is down.
I have replaced the fiber. Wired it inside the box
since the other fiber connectors had gone bad.
The adam runs for a short time then stops. It even
reboots its self. I have tried different combinations
of boards with the same result.
My next thought was a power problem at the tower. This
problem started when Marty installed his system. So
I tried a different outlet and still the same results.
Right now the ADAM is outside the building. The same

One item of interest is the radiation inlet tube on
TRH702 has most of its white paint peeled off. It appears
the paint used on this tube does not like the cold. Anyway
maybe this has something to do with the lower temperatures.
If 007 looks good, I will try changing inlet tubes.

• Previous - Next - Index

The TRHs have been in a intercomparison more for the last
20 hours. Using R and plotdat.ts I looked at the differences
between them. Most of the time it is within +- 0.05C. The sensor
in location 22m, TRH702, reads low compared to everybody else.
I do not think it is a location issue because it is located in
the middle of the IC array. The sensor on the long boom, TRH 502,
is in the middle of the difference plot so I believe the longer
boom is not affecting the measurement.
Since Marty is not ready, I am going to replace sensor 702, 22m, with
a spare unit.

Changing the data rate of the TRH to 2 saeconds did not
help the throughput. I have changed the 8 channel Ironic
to the 16 channel board. TRH data rates have been changed
back to 1 sec.

12: temp_rh, Site , Tue 21-Nov-2000 08:28:47 NZDT, data rate changed on TRH sensors

• Previous - Next - Index

The throughput on the IRONIC 8 channel board is
too slow. The data rate from the sonics is 19HZ
not 20HZ. Gordon believes this is due to the
interrupt handling on the board. As a test I decided
to slow down the data rate from the TRH units to
2 secs. It would be best if we could change the
baud rate of the TRH but that is not possible to
do on the fly.

I decided to use a short boom at the 22m height since we
were missing one long TRH boom. At the 1m height the intercomparison
bar was mounted so the 1m TRH will be attached to this structure. A long
boom will be used here. At this time I do not see the need to change
this boom to a short one. We will see what the intercomparison shows.

about some software / sonic issues, I started work on the infrastructure.
At the end of the day, all booms mounted, the adam platform mounted,
the intercomparison boom mounted, and cabling for the 3 upper TRHs done.
I hope to finish all the cable work tomorrow. I still need to run tests
on the NO system so I may be delayed a day before I can deploy.

• Previous - Next - Index

Steve O notice the sampling frequency for the
data was a little slow. He talked to Gordon about it,
and Gordon thought it may have to due with the sonics
being at the end of the serial channel assignments because
those channels got serviced last in the interrupt sequence.
So, I did some changes in the ADAM box and the sonics are
now on 200 and 201. The TRHs are channel 202 thu 207.
Will monitor with data_stats.

change the sample window to a longer period. At this time it has not
helped the questionable sonic. I changed it on another one and the sonic
started spiking. I set it back to our original value. For information,
the value changed was the LateLatch (xmt window end). Original value

The equipment arrived last night and I work into the sunshine
until late. There were problems with the network link to the data
system. I talked to Gordon early this morning about the problem
and he came up with some ideas that solved the problem. It had to do
with the name for the local host.
There was also a bad optic fiber cable. Kinda dissappointing since they
were recently fixed.
Once the network problems were solved the ADAM came up like it was
meant to. I made the necessary changes to the boot params and everything
worked ok.
I am now in the process of checking the sensors. A problem was found
in the TRH intercomparison cable which will require a change in the
serial channel assignments.
That is all for now.

A brief report on what has happened up to now.
Delays, delays,and more delays! This project has
been full of delays. It took 2 extra days to get to
the Pole due to bad weather. One extra day in Christchurch
and one in McMurcdo. The flight was long from Christchurch
to McMurdo, about 8 hours and crowded. The flight from McMurdo
to Pole was short, about 3 hours, only 11 people.
Unfortunately, flights were cancelled for the next 2 days so
the equipment did not arrive until last night.

The tower setup should not be too bad except for the weather.
The windchill is a big factor! I talked with the NOAA people
to go over the locations to mount sensors. They had some concerns
about interference with an albiedo measurement. So, decided to
put the sensors on the long side of the tower facing into the
fetch. This was probable the best side anyway.

We are short one long TRH boom. Icommunicated with Steve O. about
options and we came up with one.
