Jessie Cherry May 2013 Toolik Trip

Overview

The met station at Toolik needs to be transferred from its tripod to a tower. The field requirements for this assignment will be outlined here.

Any other information not here but could be anticipated as being useful?

To Bring from Fairbanks

• Cabling to extend thermocouple temperature profile from old enclosure to new enclosure.
• shovels for digging out buried cabling
• extension cord for moving power from old tripod to new tower
• cable splicing tools for anything that might need extending
  • soldering iron
  • butane
  • propane torch
  • solder
  • heat shrink
• extra cabling
• Toolbags
• Extra data logger (CR1000, for any instruments that aren't transferred to the new logger on this trip and or don't reach... completely just a back up item)
• small actionpacker
• sled
• Climbing harness
• CGR4 Radiometer
  • Also bring Precision Resistor for measuring CGR4 Thermistor
  • Also need to update program with calibration constants for this sensor.

Current Equipment On-Site

• New tower w/ enclosure & guy wires
• Garden web cam
• Pluvio 1 (Currently installed but broken)
• Met Station w/ soil thermocouples, radiation, lake sensors on rusted tripod
• New Multiplexer
• Pluvio 2 (needs to be installed but is in the environmental data center)... has a different base than the existing one.
• Pluvio 2 base is inside the wyoming gauge snow fence sitting on the ground

Goals

• Mount recalibrated AT/RH sensors
• Move power to the new enclosure
• Transfer as much equipment as possible to new tower
• Leave what can't be moved at the old site
• Install Pluvio 2
  • note, pluvio 1 wire is a bit short. but should be okay with pluvio 2
• Get evaporation pan working
• Install new radiometer
• Tighten guy wires and level tower

Needs

• TFS Site Wiring / cable lengths
• List cable types needed ?
• List muxes needed ?

List equipment/tools need to bring

• Conduit
• New Program (Bob Bu has draft) - Direct Link emailed 5/4/2013
  • Program Git Archive:
    • [Bob's DropBox]/logger_programs/toolik_tfs/TFScamp_CR3000.CR3
• Troubleshoot Evaporation Pan
• Figure out what needs calibration

Updates

• Pluvio 1 and Pluvio 2 use different base stands. Make sure to include the Pluvio 2 mounting hardware!
• Evaporation pan may not be in the budget this year if the gauging unit (Campbell 21531) needs to be replaced.
• Conduit isn't an immediate priority since this depends on the final setup.
