Pre Trip Data Review

  • KG IS5 Snow: WS/AT good
  • KG Trans9 Snow: WS/AT good
  • KG m64 Met:
    • Swap Barometric Pressure and fix the vent tube.
  • Teller Bottom
    • Data download: regrab file 165.dat series. (5/22 to 6/5)
  • Teller SW
    • Data all good but refresh desiccant
    • Take a minute to sort out if the 0 values in the snow sensor time series are from the bushes interfering with the signal before replacing sensor.
  • Teller Top
    • Not visited since March...
  • Teller m47

Items for October Trip

Things to grab in Fairbanks yet

  • @ room 106 a charge controller for IS2 snow site

  • @ Cabin: Another anchor or two / wire rope for snow stands year 2
  • XX CR1000 for Teller IS2 Snow
  • XX Drill
  • XX Sawzall
  • flat plate of some sort for under IS2 bases (optionally: trail mat?)

To Buy yet

  • Mineral / Baby Oil

  • 2 Dog anchors for Teller IS2 Meadow
  • TL-IS2 Snow Depth Stand 10ft pipe
    • 3/4 in x 10 ft pipe
    • 3/4" Box wrench
    • 1/4" Allen Wrench

  • Battery box lid rope / twine / nrs strap.
  • For the snow sites:
    • Guy wire
    • cable clamps
    • screed stake / dog anchor
  • ngee m64: the pvc pipe to use for keeping pressure sensor accurate over the winter

Nome Conex Instrument Inventory (May 2022 Edition)

  • Left 2 HMP155s in Nome Conex
  • Left 1 SR50A in Nome Conex
  • Left 1 BP Sensor in Nome Conex

Older Note to follow up on: Teller bottom 2022-05-20

  • Problem files
    • Micromet110.dat
    • Mm112

Teller IS2 Snow

  • Need a base plate for 4x4 to keep it from sinking further into muck. That turns out to be the source/reason for the lean.
  • Limited Lean 5/22/22 by pounding in rebar with guy wire anchor. Could use rebar cap from storage for it (or from Fairbanks)
  • Also on 5/22/22: Verified voltage of solar panel and battery. Charge controller needs replacement

Teller 47

  • Guy wire off again creek side
  • Baud rate on md485 set to 9600. I always forget so might need to adjust serial port speed before collecting here
    • Should really buy a couple of the rs232 cables for the cr6 cas sites
  • Should look at pressure data here and compare to teller bottom.
  • There are flies in the vent and it should be replaced
  • I think we have a baby oil in conex for fall 2022 geonor.

Teller 47 Snow

  • Vertical pipe bent a bit over the winter.

Teller Top

  • Was going to disconnect and reconnect wiring for HMP155 to see if the weak connection is not the sensor.
    • might also try leaving sensor turned on for longer in program (a to do for when CNR4 returns recalibrated)
    • Musk Ox within 50 meters of station prevented a visit.

Snow Stand Improvements

  • Shipped out in March parts to add a snow depth side diagonal support (just need to buy the pipe).
    • Teller 47 snow
    • KG-IS5 snow
    • Teller IS2 2x
  • Should also add back side guy wires to:
    • Teller IS2 2x
    • Teller 47 snow
    • KG-IS5 Snow 2x

Proposed Itinerary

Day 1 Sunday

  • Arrive on evening flight
  • Pick up Truck.
  • Grocery for perishables and local snacks
  • XX Swing through campus and look at the radio base station antenna
    • Should get access to the building to look at it indoors this trip though...
  • if weather cooperative / time allows visit anvil otherwise squeeze in early in trip.

Day 2

  • Drive to Teller 27
    • Gage the Creek
    • Download data from all sites at bottom
    • Replace radiometer at Teller Bottom
    • Replace snow transducers on reachable systems
    • Fix Tipping bucket
    • Teller Bottom Soil Moisture sensor need a bit of attention. No SDI 12 action.
    • Bring out step ladder for Teller Bottom CNR4
    • Teller IS2 charge controller doesn't look to be working (confirmed looking at March data download).
    • Teller sw could use one serial cable

Day 3

  • Visit Kougarok sites
  • Replace pressure sensor at met station
  • m64 met: relevel cnr4 & tipping bucket
  • Snipped the pressure vent tube but thinking I should return with something more. Like pvc pipe going to ground so there is even less chance of clogging. Like could add the T sections of drill holes in pipe for venting
  • Kg is5 snow
    • Replace battery box lid
    • Could use a sticky hook to hold serial cables up inside these boxes
  • KG South Transect Snow
    • All good here nothing to change.

Day 4

  • Drive to Teller 47 site
    • download data
    • dump precip bucket
      • need baby oil
    • level radiometer
    • (ordered a replacement SR50A for the willows site. Will need to deploy this trip)
  • Drive to teller top
    • download data
    • HMP155 cable, try redoing the connections inside the instrument box.
    • replace CNR4

Day 5

  • Council
    • download data at grid and level tipping bucket
    • disconnect radio?
      • check battery voltage in 21/22 winter.
  • Visit Skookum and check out antenna / radio

Day 6

  • Wrap up loose ends in town
  • Return home on morning flight
