Summary: Maintained fences, fixed CO2 profile system.

2014-10-07

I arrived about 11:00am. It was clear, sunny and warm with a little breeze that sprang up after a still morning. No change in conditions since last week.

The fences were all still intact. I walked the perimeter of all the fences and fixed minor things like dropping wires and askew insulating clips. I also added flagging to the top wire between posts to make the wires more visible.

I worked on the CO2 profile system on the tower. It turns out that the tube fittings on either side of the 2um filter were leaking. I cut them off and new some plastic fitting on. The plastic seemed to work, but I can replace them with brass next time Iâ€™m out.

I calibrated the LI-820: Cell T = 52.2C, Cell P = 96.3kPa
Zero offset: 10.1 ppm
Span offset: -8.9ppm
Precal Coefs: zero = 0.9656, Span = 0.8022
Postcal Coefs: zero = 0.9684, Span = 0.8104
