Data Notes
 +
* Double-check thermistor equations
 +
* double-check precision resistor values.
 +
 +
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.

http://ngeedata.iarc.uaf.edu/data/teller_top/
 +
 +
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.
 +
* http://ngeedata.iarc.uaf.edu/data/teller_top_soil/
 +
 +
Teller Top Thermal Conductivity:
 +
* something funky going on here, too, as in precision resistor may be off and also the data is quite spikey.
