Summary: rainy day, cows broke fences, still having troubles swapping tower computer.


I arrived with Siyan about 10:00am. It was mostly cloudy and cool with a little rain clearing up later in the day. The top centimeter or so of the soil was damp. Cows are around and broke all the fences again. We repaired the fences.

I tried to swap the tower computer again, but cannot make a connection to the Phenocam with the Compute stick. The field computer to the Phenocam works, putting the computer at the top and connecting to the compute stick at the bottom works. So there is something specific to the compute stick and the Phenocam. I can test with one of the old web cams in the lab. Maybe power the usb hub.

The flow rate for the CO2 profile was very low. I replaced the filters at the inlets, but that didn’t seem to improve the flow much. The IRGA values looked okay, but I could not calibrate.

Siyan collected data, did the wells, dendrometers, and midday water potential.
