Weather: another nice day, clear and cool, warrming, then clouds, then some wind, then chilly when the direct sun is gone
People: no change
Bunch of misc tasks:
- Read all serial numbers
- Finished Leica shooting all sensor positions (today was just the PIs)
- Finished dressing cables
- Added snow pressure port tubing at c
- Swapped 5m.c EC150, since it was reading way offscale
- Finally figured out that the snow pillow problem was our prompting. Isabel, with advice from Gary, figured out how to add "offset" to the configs to prompt these sensors as they need to be. Now working!
- Deployed the rest of Ethan's lidars, though he has some Pi3 issues. We leant him one of our Pi3s out of a spare DSM.
- Jessica's students deployed the Tsnows at d and ue. They won't deploy Tsnows at uw, but instead will log data from them using their laptop manually episodically. I promised to give them a D9 to Bulgin cable for this (mote to laptop with a real serial port). I haven't mentioned powering the mote...
- The temperature screen was set up and demonstrated for about an hour – interesting images!
- Pulled the haul line on the 20 m tower and rotated haul boom to the downwind side.
Our todo for tomorrow (then planning to leave Sat):
- Further help Ethan debug his connectivity issues
- Take a gravimetric sample
- Re-measure guy tensions
- Clean up the equipment pile
At some point, we have been asked to log some of the other messages (at least SWE) coming out of the snow pillows, but that can be set up from Boulder.

Below is the plot of the sum of the four loads (converted to lb) from the snow pillows (1–4) as a function of sample number while Jessica stood on each one in order and Eli stood on 2 after her. I've removed the tare as the median of the 20 samples prior. They seem to work.
