Spring 2016 site visit

• take photos of sensors without pics on instrumentation site
• bring measuring cup set for leveling UVA and UVB sensors
• wire junction to split all instruments needing 12V from logger

• install new evap pan
  • leak test (marine epoxy in case of leaks. should be up in the EDC office)
  • clean out bottom
  • field calibrate

Calibrate

   Fill pan partway with water, measure height with ruler in mm
   Measure voltage by reading the EvapLevelTemp variable on the program
   Add more water, measure water depth in pan
   Measure voltage
   Calculate multiplier and offset using y = mx+b
       m(multiplier) = (height1-height2)/(voltage2-voltage1)
       b(offset) = height1-(m*voltage1) 

Change multiplier and offset in program

• swap in fancier wind sensor
• fill in serial numbers of all instruments/loggers on google sheet
• calibrate tipping bucket
  • fill bottle to line, use smallest orifice, do this 3 times
  • should be 30mm per bottle, so 90mm total
  • change multiplier in program if necessary
• do accuracy test on Pluvio
  • received software in ftp from ott (on my fancy laptop, need to transfer to toughbook)
  • need usb cable

• swap out HMP155s
  • write down which height is which SN
• swap out quantum sensors
  • bring mini wrench to replace them
  • figure out what the connection is like at toolik
  • change calibration constant?
• download garden cam images
  • bring replacement batteries
• we zero out the CMP6, but not the CNR4. reconsider?
• swap CNR4
• install new barometer
  • change program calibration constants
• change UVA + UVB program calibration constants: UVA:0.0221, UVB: 0.00178 (per Lija's email)
• remove old radio
• get field books from Brie

• To change on instrumentation website
  • pluvio is actually version 2
  • lake temp measurement
  • barometer

things that will be different for program

• evap pan calibration
• possible tipping bucket calibration
• possible pluvio calibration

• to bring
  • laptop + charger
  • field laptop + charger
  • tipping bucket calibration box
  • gloves, hat(warm and sun)
  • tools
  • wire junction
  • hiking boots,rubber boots,running shoes
  • field book
  • usb cable for pluvio
  • cookies for brie
  • instruments
    • anemometer
    • CNR4
    • Two HMP155s
