Summary: Standard field work, cold and gray, swapped 7500s, co2 profile system turned off due to dead pump, fixed IP address for camera images.

2016-12-07

I arrived about 12:00 with Siyan, Daphne and Jorge Perez. It was cold and mostly cloudy with a light breeze. All the trees here have lost their leaves. The ground was damp but not soggy and no puddles.

Daphne and Jorge swapped 7500s and cleaned the Tower radiation sensors. At the Tower, sn 0418 came off and sn 0035 went on. At the Floor sn 0976 came off and sn 0073 went on.

Siyan did the standard fieldwork. I collected the data.

The tower system lost power about a week ago due to low solar power. At this time the co2 profile system stopped sending data. The CR10x was running, but its data looks corrupted when I tried to download it. I did not get it all so there still might be some good data there. Regardless, the pump was also dead. I removed the pump and removed power from the IRGA and CR10x. I can try to start it back up with a new pump next time.

We also lost the camera images when the power went out. When the computer rebooted the Ethernet adapter reloaded as a new network connection and did not get the correct IP address. I fixed the IP address and images were flowing again.

Daphne serviced the zcams.
