From the storm yesterday (10 Nov), most of the site is covered with snow.  The coverage ranges from a clear ice glaze (that probably melted and refroze today) to drifts of up to 8cm.  (Larry says that he found drifts of more than 20cm near the crests of the hills.)  Caution for snow-covered holes again!  (Once I found a clear path, I tried to walk along my footprints on the return journey.)

I did look carefully at the radiometers and LiCors.  From the winds today (often 10m/s), all traces of snow had been blown away and optics looked perfect.  Thus, I didn't attempt to clean anything.  Kryptons are both reading > 2V, so they are fine.

This TRH has been flakey lately, dropping out, but then coming back on its own.

Here's the result of a data_dump of data late on Nov 9, and then using awk to look for gaps over 2 seconds. There are 10 gaps over 2 seconds in this 6 hours, one of them 355 seconds, and one 5678:

One can see bad characters just before the 355 second gap above:

Similar bad characters were seen at the other gaps.

Serial port 5 shows 17 fe (framing errors) and 3 brks since the last reboot 2 days ago. The other serial ports look clean:

My best guess is that it's a cable problem.

Installed the EC100 w/ sonic at Ap8.  Saw power and sonic light green while the gas light went from orange to red.  [shrugging]  But it's installed at 3m with a pressure port.  I believe it left it on port 7.

Weather:

Great sunrise but mid-low level clouds moving into the area.  Chilly with a breeze this morning.  Just hovering above freezing with high humidity.

Status:

All systems reporting.  Notice that two baro's are reporting RIP, that is because we have changed from the PTB220 to the Nano-barometers.  Realize that more instruments are being added to Ap8 and we should watch the power on that station.

To Do:

- Will deploy the EC100 with it's sonic on Ap8.  Everything is ready to go and I will get in contact with Gordon to see if we can see it.  We had trouble with seeing it last night.

Three nano barometers were installed at A11, A5 and Main towers.  Gordon got them to communicate but we still need to config it's outputs.

Chris hooked up the EC150 via USB to the flux laptop. It comes up as a typical serial device /dev/ttyUSB0, so I talked to it with minicom, 115200 baud. It is currently set for 10Hz reporting, so I didn't change anything.

Chris substituted Paroscientific 6000 nano-barometers for the Vaisala PTBs at site 10 and at 1 meter on the main tower.

He will add a Paro 6000 to site 5 later today. Site 5 doesn't currently have a barometer, and he needs to modify the 1m boom.

The barometers were reporting at 1 Hz in some other units than millibars:

*000111.95841\r\n
*000111.95840\r\n
*000111.95839\r\n
*000111.95844\r\n

I sent them the commands documented in http://wiki.eol.ucar.edu/sew/ISFS/SensorInformation/NanoParo, so that they report at about 13 Hz, in millibars.

With this modification, site 5 becomes a Aph station, rather than a Ah. On that DSM, I've left its hostname as Ah5, and just added the barometer to the catalog for Ah_DSMs.

For a short period of time I ran an Aph config on 5, which garbled up the sensor <-> id mapping:

• 0.5m TRH on port 1 ingested as barometer, id: 5,10
• 2m TRH on port 5 ingested as 0.5m TRH, id: 5,40
• handar on port 6 ingested as 2m TRH, id: 5,50
• PWR mote on port 7 ingested as Handar, id: 5,60

Depending on whether the data records parse with the wrong sensor tag, data will need to be edited out. I believe they are all in the file Ah5_20121109_180123.dat, and the real-time isfs file. The file Ah5_20121109_182039.dat has the correct config (Ah_DSM with the barometer added to port 8)

Updated the XML on the servers (gully, flux and at EOL). On the servers, Ah5 is now an Aph_DSM.

Weather:

CHILLY!  Temperatures are freezing and high humidity.  Frost on grass this morning.  High to mid-level clouds.  "Red skies in the morning..."  Winds are calm to null.

Status:

All stations are reporting.  

To Do:

Finish with mounting EC150.

Help ISS with the RASS.

Collect as many tumbleweeds as I can and mark them.  I will release them up gully and see which weed wins.  Tumble on!

The flux system is reporting errors related to its Seagate disk. ST9160411ASG, /dev/sbd. Fortunately the software RAID is working, and it is staying up, using the Western digital drive, WDC WD1600BJKT on /dev/sda.

Weather:

Chilly today.  Winds are blowing and temperature is having a hard time to get to 10C.  Mid-level clouds are keeping the sun from shinning.

Status:

Gandered the Gully and it all looks good.  Everyone is communicating today and all playing nice.

To Do:

Check out Stations 2,11 and C for nano and EC150 installment.

Oh my!

I have cleaned radiometers, Kryptons and Licors.  

Noticed the 0.5m TRH at station 3 was not reporting.  If I try to recycle power on port, nothing happens.  If I recycle power on station it works for a few seconds.  So I went out to station 3 and decided to replace the TRH probe.  Rebooted system and awaiting results.

Removed probe 024 and put in probe 048.  Funny.

Weather:

Very pleasant out.  Light winds with mostly sunny skies.  ~13C w/ 25% Rh

Status:

All systems reporting.  A lot of cows by water tower this morning.  Hopefully, they do not have a plan to run down the fence and get into the testing area.

To Do:

- Reboot RASS for APG.

- Check on TRH confusion on main tower.

- Make my bed.
