    • 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
