Teller Lower Station

Tape Color is BLUE

To Bring:

• Put the 3m tripod built from tripod kit here. (The heaviest steel tripod, blue tape on it)
• vertical mast will be 10 foot 1.5" schedule 40 pipe with 1.5 to 1" coupler on top.
• primary instrument box will be mounted at about 1 meter above the ground surface
• secondary instrument box will be mounted below it.
• solar panel will be mounted above primary instrument box and face south.
• cross arm
• Battery box in basement needs holes cut for 1/2" liquid-tite (ship battery box filled with instruments
• Instrument box with 1 CR1000 and AM416 is on site in the shrubs with
• Bring a second instrument box with 1 AM16/32 for met instruments.

Outstanding Tripod items

• Cross arm support brackets and such
• mount am16/32 to second instrument box
• send instruments & battery box on second freight run
• Stabilizer for net radiometer support arm.
  • used cross arm brackets last time... need to dig them out and make sure we have enough.
  • also could use ubolts and unistrut.

Cross Arms

• Net Radiometer skin temperature
  • need to track down unistrut & strut clamps for stabilization (or ubolts)
• small cross arm for air temperature
• RM Young should mount to top without issue.
• Precip stand is already out there
• Need to figure out where NDVI sensors point. & do we have all supplies for that...

Sensors

To Bring:

• 015103 WS/WD
  • Make up cable for it
• CR200 for measuring Pressure Transducers
• 5 pcs VITEL Hydraprobe II
  • Need to set IDs
• 4 pcs East30 sensors thermal conductivity or specific heat
  • also interface board
  • also measure the heater resistance of each
• Cable protection
• cable ties & hose clamps for securing cabling to tripod
• VATP 1504 - see email for thermistor calibration offsets

Sensor Heights

• Anemometer @ top of tripod / ~3 meters
• HMP155 @ 1.5m above ground surface
• Barometric Pressure - in instrument box
• Net Radiation -
• Snow Temperature profile -- ground surface in the shrubs
• Snow Depth 1 -- 2m on cross arm off station
• Snow Depth 2 -- in shrubs on a stand.

Already at site:

• HMP155
  • thinking about bringing out a replacement temperature head though because the one in place has been on the fritz over the summer.
• TE525MM
• CNR4 w/bracket
• Two Batteries
• Solar Panel
• Charge Controller

Extras

• need to yet sort out how Met AM16/32 will attach
• need to drill out second instrument box so that cables can enter.
• Need to permanentify the solar panel
  • bring solar panel from Fairbanks and but need to make a mount for it yet.
• Measure East30 sensor resistance
• label all subsurface sensors
• Need to survey in all instruments with GPS
• Reuse batteries that are already out here, no new batteries needed.
• think about how to mount iridium here...

To Ship:

• Tripod

Installation Guidance:

• Unpack Tripod Base
  • Set in approximate position
• Loosen bolts at base so that legs can fold out and also so that the mast can slip into the bottom bracket
• The mast is 1.5" schedule 40 pipe. Screw a 1.5" to 1" coupler on top and follow with a 1' long schedule 40 pipe.
• on the other end, slip the 1.5" nurail cross fitting over it and slide it up
• Mount the anemometer to the top
• with the tripod tipped, orient the tower so that one leg points north
• rotate the tripod to vertical
• mount the secondary instrument box on the opposite side of the pipe from the primary box.
  • need the 5.3cm ubolts 2pcs
• mount the primary instrument box above it on the tower
  • use the 1.5" unistrut clamps
• mount the solar panel on the instrument tower
• mount the HMP155 radiation shield at 1.5m above the ground surface

Additional Electrical supplies

• 2 pcs butt splices for solar panel to charge controller cable
