I arrived about 11:00PST with Siyan. It was clear, sunny and hot with little to no wind. The ground was visibly damp in low spots. Grass has sprouted and is about 5am tall already. The trees still look good and may have postponed the leaf drop that I observed last time.

I was going to setup the Stardot camera from Andrew Richarson?s lab, but given the problems I had installing the one at Vaira and being a short on time I postponed this.

I checked the CO2 profile system. I could not figure out what was wrong with the LI800. I reset its settings and it stopped being railed at 1000ppm but was reading mostly about zero. I tried to calibrate it, but this did not improve its performance, in fact it said it could not complete the span calibration. So I pulled it out and swapped in the LI820 from the lab. This one seemed to work, though you need to use the LI820 software to talk to it. The LI820 software in the tower PC is version 1 and is not completely compatible with the newest firmware in the LI820.

About 2PM PDT, I started an EMI survey. This time I was about to load a way point layer to the GPS so I had some better reference as to where I was supposed to be walking. I finished the survey in about two hours, though it might be a little less dense than Trenton?s, especially south of the road. In some places I could still see tracks from last time.
