2022 NGEE Nome October Trip

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

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
  • level tipping bucket
  • Teller Bottom Soil Moisture sensor need a bit of attention. No SDI 12 action.
  • Buy and bring out a short 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
