I arrived about 9:30 with Sara, Carina and Cristina. It was sunny with some scattered high clouds and cool with a wind from the west. The pepper weed and other weeds in the field look a little greener today.

When we arrived the LGR read:
9:37PDT, 20.93C, 144.70Torr, 15.019usec, 10Hz, 1.771ppm

The CH4 concentration seems low.

I collected all data.

Sara made soil chamber measurements. Carina and Christina did the other standard fieldwork.

We worked on the soil CO2 program and system some more. We installed two Theta probes near the west set of soil CO2 sensors. The theta probes went in vertically the first at about -8cm, the second probe sn 54/007 at -2cm.

I checked the incoming PAR sensor, it seemed clean. I think I remember cleaning some bird poop off it last week.

I removed the power from the old web cam and from the Ethernet router. Future images will come from the autocam only.
