Spring 2016 site visit

• bring measuring cup set for leveling UVA and UVB sensors
• wire junction to split all instruments needing 12V from logger
• swap in fancier wind sensor
• fill in serial numbers of all instruments/loggers on google sheet
• 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?
• swap CNR4
• remove old radio
• get field books from Brie
• install new barometer
  • change program calibration constants
• change UVA + UVB program calibration constants: UVA:0.0221, UVB: 0.00178 (per Lija's email)
• we zero out the CMP6, but not the CNR4. reconsider?

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

calibrate precip

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

Pluvio accuracy test

• • received software in ftp from ott (on my fancy laptop, need to transfer to toughbook)
  • need usb cable

download garden cam images

• • bring replacement batteries
  • to turn off: press and hold organge power button until 3 beeps and green LED turns off
  • remove drive, download and clear images on computer
  • to turn on:press and hold organge power button until green LED lights up. after a few sec beep twice. green LED every 15 sec indicates normal running. if any other beeping or lights, consult manual

take photos of sensors without pics on instrumentation site

• HMP155
• wind sensors
• snow dept
• barometer
• evap pan

program changes

• evap pan calibration
• possible tipping bucket calibration
