23 Jan: Oncley & Militzer
Purpose: Replace prop since twice has stalled for several hours overnight; new mote software?
1307: Aborted due to mud -- less than the last time we were there (primary because the mud was more frozen), but still very sloppy. Recommed using the pickup next time.
23 Jan: Oncley&Militzer
Conditions: just a bit of snow clumped on the curb
1210: adjusted SPN-1 level (off by about a bubble -- the soil post is leaning)
1213: dry wiped radiometers
Until 1225: messed with shadowband adjustment. Shifted the aziumth a bit to point nearly S, adjusted elevation to 60 deg (from 53), adjusted sensor level, moved collar to center shadow.

After a nice morning, yesterday turned cloudy with snow flurries most of the day.
This morning has mostly clear skies, with inversion starting in the valley.
Some frost on the van windshield at the Rez this morning.
Summary:
- krypton at 3 was bad most of yesterday, but recovered overnight.
- modem at 2 appears to have lost settings -- we'll reprogram it today
- Shadowbands at 1&7 should be adjusted. Sebastian will do 1 and we'll do 7.
- Prop-vane at 6 has stalled at night for the second time.

21 Jan: Militzer&Oncley
Purpose: Entire station lost communication at about 1:30 today (while we were giving the tour of site5).
We've seen lots of reconnects in dyndns both since midnight last night and during the day yesterday.
Steps:
Cradlepoint WAN quick blinking/no USB or WLAN LED. Cycled power to cradlepoint. USB now on; WAN blinking; external connection via dyndns still not up, though www.dyndns does show request; am able to ssh in with IP address; data acquisition has been running.
See in messages that router_check ran, now access via isfs4.dyndns is working.
At Gordon's suggestion, did a bunch of tests of check_router script (which should have fixed this problem by itself). It has a long time-out of 3--5minutes, but did work as expected with the LAN cable unplugged. We next want to run a test by unplugging the 3G modem, but ran out of power on our laptop. We'll do this test tomorrow on the spare in the base.
P.S. The next day, we did this test on the spare, which worked exactly as expected. Thus, this failure at wvally4 is still a mystery.
21 Jan: Oncley&Militzer
Purpose: Class tour; reprogram motes; clean radiometers
Didn't record exact time, but everything done between 1300-1345. Should be able to tell from mote data.
The data may record that I did an "eio 5 0/1" cycle as a demonstration. The radiometers had been done by this time.
PS: From the data, the times of these events were:
12:57:50 rad mote restarted
13:00:15 main soil mote restarted
13:04:37 aux soil mote restarted
13:13:20 Rsw.in cleaned
13:13:40 Rlw.in cleaned
13:13:50 Rlw.out cleaned
13:13:55 Rsw.out cleaned
13:22:22 TRH eio

20 Jan: Oncley & Militzer:
Purpose: Adjust shadowband; nail polish mote antennae; scout for tour
Conditions: water all over the field -- perhaps 50% cover. Not good for a 14-person tour... Soil clearly at field capacity, though probably is frozen at some depth. Some of the water has an ice film (despite Tsoil reading about +4).
1634: Adjust shadowband - azimuth change from about 170 to 180 degrees; elevation change from about 35 to 53 degrees; releveled; adjust ring up a bit to center shadow.
about the same time...reprogram motes with new code; forgot to turn back on
1650: motes back alive

Absolutely clear morning with great visibility. There appears to be fog over the lake.
There was frost on the van windows at the Rez.
Everything's working, so we're off to Campbell Sci.

19 Jan: Oncley&Militzer
Purpose: take soil sample
Conditions: Still a glaze of snow everywhere, but lots of squishy mud at the surface -- 2 out of 5 on the mucky scale. (Not sure if it could be torn down even using the pick-up.)
1420: soil core main
1425: soil core aux
nail polish all mote antenna
wiped off clear-hard ice from Rsw.in; dessicants ok
19 Jan: (a frustrated) Militzer & Oncley
Reason: Rad mote had died at 0630, but fixed itself at 1045. Still going to check it out...
Conditions: mostly solid deck across the valley, though broken towards the western mountains. No snow at site.
1311: ID17 probably used the new version of code to internally reset the XBee. It hadn't had a heartbeat, so it would have used the internal timers, which was set to reset every 6 hours. We just changed it to 3 hours (#17xr=10800).
1317: Relevel SPN-1 (about 80% bubble off) -- it appears that the post may have shifted a bit, perhaps with soils thawing?; wiped ice off of dome
1318: Wiped a bit of ice from Rsw.in dome.
nail polished both mote antennae
1318-1320: Downloaded microSD data from rad mote, just to test (later) if data were lost during the 3 hours this morning. We think the data are just fine.
1328: reprogrammed ID16 with auto-resetting/eeprom/etc. code
19 Jan: Oncley&Militzer
Purpose: restart radiometer mote; take soil core
Conditions: broken alto-cu; snow completely gone around site
1137: Rad mote not working; removed for diagnosis;
water came in through the XBee antenna, dribbled down the XBee and got into the real-time-clock capacitors on the back of the board, taking out the clock. Data would have been lost. Copied data file to Oncley's Mac. Also found broken solder connection on GPS backup battery holder. Mote starts okay when pressing on this holder!
1140: Soil core taken into containers 1
1153: blotted water off radiometers (though no data being taken yet)
reprogrammed spare mote to be used at this site
1234: Installed new mote; all data working and okay
added nail polish around mote antennae to avoid a recurrence of this problem.

Gsoil: ok. All sites had negative fluxes yesterday -60 -- +20 W/m2, almost like "normal" conditions
Qsoil: ok. Lots of movement, upward from rain
Cvsoil: ok. Mostly tracked Qsoil increases yesterday
I note that recent soilT profiles show intense heating of the top soil layers during the day, followed by almost instantaneous cooling back to below freezing. Indeed, there is a "rebound" effect where the top soil cools to below the lower soil, associated with a change of sign in the heat flux. I believe these large changes should indicate a low heat capacity, though the Cv values are just average. I do note that the soil density is lowest at river7, so Cp (mass-weighted) may be quite low.
