Fairbanks To Do

• Dry desiccant for CNR4 (All four in Utqiagvik)
• Dry Desiccant for Teller SW (I have a bottle for loose out there now plus the PT tubes
• Hardware inventory for Snow deployment
  • SR50A
  • Mounting brackets
  • Review sketch
• figure out the proper way to secure solar panels for snow
• think hard about improving solar panel setup at Teller m47.
• Grab Survey controller and pelican case etc.
• Charge batteries

Teller 27 General

• Survey GCP
• Help

Teller Bottom To Do

• Secure tipping bucket
  • bring out drill
  • bring out self tapping screws, 3x

Teller SW To Do

• Solar Panel Fixes (research in Fairbanks)
• Deploy second PT
• don't forget to grab more desiccant
• Add a snow sensor here?

Teller m47

• Think hard about getting the solar panel off the ground a bit more
• Install Tipping bucket
• new dry soil pit / dig up and replace original
  • add soil moisture probes, too.
• review what i proposed
  • 4 soil moisture probes
  • air temp
  • second snow sensor
  • batteries
  • solar panel
  • cr800

Council

• Survey Sigrid / Margaret's sites

NGEE Kougarok

• Survey GCP

Replace top mast and anemometer

• Full replacement anemometer
  • potentially could reuse one from storage but will need:
    • propeller (need to order)
    • cable (fairbanks supplies)
    • right size cord grip (I'm sure this is found in my Fairbanks supplies... or the one that's currently broken... )
    • unistrut & 1" pipe & ubolts (try the square ones?)
    • nylock nuts
• new brown tarp
• Raspberry pi to download?
  • memory card...
• put soil moisture probe back in ground.
• I guess remove VATP from program to make the data record last longer.

K1 Burn

• Should visit since I haven't heard from it.
• change out the SR50A transducer
• bring a thermistor for air temp (assuming there will be some damages)
• I guess, given that it isn't on the radio network any more I should expect something worse.
  • power cable to fix a chewed solar panel
  • coax in case that was chewed

K2 Met

• Station visit required
• Bring out desiccant for radiometers (loose)
• replace CR10X but change the watch battery on the logger to take out first.

K3 Mauze Gulch

• No idea... need to review how I left things in 2019.

Things to Order

Related: Need to separate out by project ID

• Campbell Scientific
  • RM Young anemometer propellers ( $70 at RM Young website) https://www.youngusa.com ; p/n 08214-45)
  • Texas Electronics Tipping Bucket
    • cobble from parts?
  • SR50A transducers
    • new deployment
    • existing @ Utqiagvik = 8 = 2A + 2B + 3C + 1D
    • existing @ SP = 10 = 4 (K1 to K3 + ngee m64) + 1 m47 + 4 m27 + 1 council?
  • 2.5 psi for Teller SW

To Buy

• Step ladder for teller bottom
• Bring out a replacement memory card for the Teller Bottom CFM module

General

• 2 Trimble Yellow batteries left in NW Campus Warm Storage

Seward Peninsula

• SR50A transducer replacement (fall activity)
• (2019) bring out one step stool to level teller bottom radiometer.
• (2019) bring out tap, die, drill, drill bit, screw for teller bottom radiometer.
  • screw...
• also replace cnr4 desiccant since the unit didn't look like it was sealing right with this missing screw.
• Bring out additional desiccant? for box
• Teller SW desiccant replacement
• (2019) Redrill hole for C1 Grid temperature probe
  • what is needed for this?
• Measure Creek Flow
  • salt slug, n=2 samples of 50g / known volume of water
• Re-level radiometers
• polish radiometer domes
• Measure thermistors resistances at Teller Bottom and add them to fieldbook.
  • There are a couple with a 0.5C offset at spring freezing point so I think they may be failing and or something...
  • Related: I'm wondering if the delay between measurements should be increased for the thermistor measurements.
  • Also related: perhaps add a second string up at teller top?
  • sort of some additional homework is that I saw instability in a number of thermistors when measuring up top. I suspect but haven't verified that this instability is an indicator for the wonky temperatures seen in the data but need to confirm.
• 6/11/2018 In Fairbanks... down in 106 / the basement there is a box of 12" nails. Would be good to grab three for the Teller SW solar panel tripod
• I should do some experiments with the thermal conductivity thermistors in office/lab to see if I can reduce the noisiness.
• finish surveying vegetation plots

Kougarok

• bring out a serial cable for box (removed it in fall 2018)
• get a compass reading on anemometer
  • leave a compass in the box

Teller SW Flow

• left a metal meter stick at the site
• fieldbook
• YSI conductivity meter
  • manual
• electrical tape
• batteries

Radiation Level:

• step ladder
• a bit of wood to provide better base for step ladder
• phillips screwdriver for level

Radiation Desiccant Swap:

• Step ladder
• small CSI phillips
• K&Z desiccant pack
• anti-corrosion goo

Teller Top Soil Temperatures

• Volt meter
• fieldbook
  • learned but need to confirm that the thermistors with a capacitance are ones that are unstable and failing.

Utqiagvik

• Intensive Site A HMP155 failed (3.5m)
• Intensive Site B HMP155 failed (1.4m)
• Intensive Site C HMP155 failed
• need to replace the network cable running from the computer to the network switch. It cuts out with minimal bumping.... but station is finally back online!!!
• Site A SR50A transducers have failed
• some subsurface items are beginning to fail.
• bring up clear tape and a biz card to label the computer
• bring up the nuc plate and wood screws and other screw packet to mount nuc to wall
