NGEE Barrow August 2016

I'm starting this for the Bill & Lily trip.

September Items that would be bonus for August

(Sounds like September trip may not happen... hopefully you are able to do these) I have these items on the September trip but if you have time it would be awesome to do them in August and even better if we don't need the September trip: To Do:

• Replace all SR50A snow transducers
  • 2pcs @ A, 2 pcs @ B, 3pcs @ C, 1pcs @ D
  • general rule, station ID = 7, trough = 8, at C rim ID = 9
  • tools required:
    • phillips screw driver
    • 1/4" nutdriver if you remove the sensor from the stand to swap out.
    • 1/2" wrench/nut driver if you remove the sensor.

• Near the boardwalk to the C site is Anna Liljedahl's Soil moisture grid site. There is an MD485 wired link between that CR1000 and the C site. Could we talk through checking this link. Haven't heard from the logger since last fall. Also worth it to download the data but I think fixing whatever is ailing the MD485 link will get the telemetry working again.
  • find white campbel box on ground with cr1000 pakbus ID: 404
  • download data
  • power cycle
  • it is possible that the C site has forgotten that it is a pakbus router.

• check compact flash memory module at A
  • download program
  • connect with device config, file control, format USR drive

• Swap out all Wind Speed Sensors
  • 3m @ A, B, C will require a ladder
  • 1.2m @ A,B, C, D
  • These are Met One 014A sensors so the tricky part I think will be the corrosion. The sensor cable screws on the base which I think won't be too bad but might require a channel lock.
  • The cups though will require an allen wrench, small, and the corrosion may make removing them all but impossible. I'm not sure.
  • we'll need to add anti corrosion goo to the fittings on replacement, too.
• check level on radiometers
• Could you roll up the extension cord running from the eddy covariance tower to Sina's thermal IR tower location? Take back to storage?
  • We should ask Stan / Brian if it is still out there
• take photos of ARM precip fence

Take from Barrow from Nome (we have permission):

• 5 pieces of trail mat

To Bring:

• 014A replacements
• couple small tools
  • 1/2" wrench/nut driver
  • 1/4" wrench/nutdriver
  • metric allen wrenches
• ladder
• SR50A transducers
• anti corrosion goo

In Action packer already:

• disc
• 8 sr50a transducers
• assortment of zip ties, hose clamps, duct tape, electrical tape
• 7 met one ws rods, 7 met one ws cups
  • allen wrench taped to one of rods (also one of the yellow set in my tool kit fits)
• anti corrosion goo
