  • Car Rental Reservation: R41747
    • 9/29 - 10/6
  • Nugget reservation 1346


Activities:

  • Nome
    • find new base station location with Chad
    • return GCI cable modem from Boxer Apartments
  • teller
    • move snow poles to TLA line
    • put one snow pole in each actual snow course center of X for the IS crosses.
    • remove remaining poles
  • teller bottom:
    • check soil moisture #5 (bottom) seems to be not powered / connected.
  • teller top:
    • double-check data
    • thermal conductivity probes working?
    • maybe replace cnr4
      • and or drill out stripped screws
  • replace memory card in camera
  • teller bottom
  • replace memory card in camera
    • sr50a transducer replacement, 2x
    • remove 1 PT
    • discharge measurement
  • Kougarok m64
    • bring guy wire markers for K64 met station (at uaf storage)
    • setup snow grid for spring (surveying)
      • 9/25 waiting on geopdf & shape files from Lauren for this.
    • survey the remaining intensive sites out there:
      • IS5, IS6, IS8
    • soil pit.............
    • altar shield
      • need 2 2x4 chunks for base
      • need 2 more pieces of functional altar shield
      • need wood screws to screw vertical pipes to base.
  • Original Kougarok:
    • download data by radio
  • Council
    • fix program at C1 Grid
    • download C2 blueberry data over radio
    • push snow off eddy system.

Sensor Issues

Data Notes

  • Double-check thermistor equations
  • double-check precision resistor values.
  • think about bringing car adapter plus aligator clips etc out so we can tie into station batteries during program compilation.

Teller Bottom Soil:

  • teller bottom: confirm that thermistor values as-built match resistor in field.
  • Soil Moisture #5... is it connected?
  • Heat Flux Plates are doing the wrong thing... are they measured right?
  • thermal conductivity thermistors... it kind of looks like the measurement is still settling. The measurement is quite spikey from time to time.
  • Looks like VATP3 shifted on 4/21.
  • same for VATP4
  • same for VATP 6
  • same for vatp 8
  • same for vatp 9
  • can see water pulse around 4/21 in the lower thermistors.

Teller Bottom Spectral:

  • Decagon Sensors look good

Teller Bottom Radiation:

  • Looks good just need to correct albedo for nighttime.

Teller Bottom Snow Temp Profile:

  • Looks pretty good

Teller Bottom Thermal Conductivity:

  • data is spikey, in soil pit temperatures

Teller Top Met

  • HMP155 is still broken.
  • All other sensors look good.

Teller Top Soil:

  • I'm suspicious that the precision resistor values for teller top aren't correct.
  • vatp4 freezing point is at 2 deg C
  • I think there was quite a bit of water running down the probe during snowmelt.

Teller Top Thermal Conductivity:

  • something funky going on here, too, as in precision resistor may be off and also the data is quite spikey.

Kougarok Mile 64 Met

  • skin temperature looks like there is a loose wire
  • Other sensors look good.

Kougarok Mile 64 Spectral

  • all sensors look good

Kougarok Mile 64 Soil
