Just to start a list of what to do when/if(!) we get back next week – a fairly long list for 3 days!:

Site issues:

  • dcs is totally down.  It appears to have lost power on 21 Dec soon after being powered up and subsequently died on 26 Dec.  Could the Victron have V/I limit settings set incorrectly?
  • pc is totally down.  Similarly, it lost power on 15 Dec soon after being powered up and died 23 Dec.
  • dc stopped connecting today (30 Dec).  Power was good when it stopped – a modem issue?
  • lc power cord was cut by plow.  Might stay up until we get there and replace the cord.
  • up may or may not have a power drop, so might need to create another solar farm. (Do we have cables?)

Existing sensor issues:

  • Most sonics are reporting NA, though they did work initially.  Assuming this is ice related (try more heating?), but might check with Campbell to see if a configuration change would help.
  • Most EC150s also show missing data.  However, in at least one case, I've found the EC150 data to be okay – just missing because statsproc processes it in a group with the sonic data that ARE bad.  Hopefully, fixing the sonics will bring back the EC150 values.
  • A thermocouple appears to have been plugged in at sh on 19 Dec, but seems to have died on 21 Dec – just 2 days later.  While it was plugged in, the data look good, though not exactly like tc (maybe a good thing).  I do see noise above 3Hz during the day and 8Hz at night.
  • Rfan.3m.prs is bad (T/RH ok).  Housing should be replaced?
  • Tsoil.mw is all -273.  Hopefully, just a loose Binder connector.
  • HRXL.cc stopped reporting 24 Dec.

Sensor changes:

  • reconfigure radiometers into operational mode at dcs and prs.  Have new mounting for 0.5m radiometer "paddles".
    • move CVF4 Rlws to darkhorse
    • move other paddles to 0.5, 7, and 32m (booms for 7 and 32 are on site at each site) – lots of cables to redo.  Sebastian will help.
  • attach thermocouples and loggers to towers at dcs and prs.  Eric said he'd do most of this work.
  • raise both TTs
  • test heating scripts

Standard operations:

  • finish recording serial numbers (a table has been started in this wiki)
  • take site photos (maybe Dan has already done?)
  • shoot boom angles (compass, then Leica)
  • take the first set of gravimetric measurements (though freezing soil probably will have moisture that the EC-5 doesn't see).
  • No labels
