Summary: Regular data collection/cleaning, eddy clock -1min, dfPAR still needs to be replaced, lost 2.5 days of data from power outage

East End

Mike and I arrived at 14:10 PST. It was cold but mostly sunny. There were thin clouds and/or smog near the horizon. We could hear sounds of hunting, but not too close to us. The staff gauge read 41 cm. The precip bucket tipped once as I walked by it.

I downloaded met, cam, and USB GHG data. I downloaded the miniDOT data and changed its desiccant. The wash reservoir was 1/3 empty; Mike refilled it. There was a power outage for about 2.5 days where we lost all data. We should check the batteries next time--we just replaced this battery bank with all new batteries last winter.

I changed the eddy clock -1min from 14:29 to 14:28 to match the laptop time and restarted logging. The eddy clock is rarely fast compared to the laptop time; keep an eye on this.

I cleaned flux and rad sensors. I checked the conductivity sensor as part of its routine check every 3 months and confirmed the orifice was clean.

There is still no dfPAR here. We removed it at the last visit because the shadowband was not rotating. I need to swap out the motor and test it in the lab before installing it next time.

We left at 14:35 PST.
