Summary: Missing Phenocam image, replaced clock batteries in zcam 2 and 3, checking solar equipment

Tonzi
2018-04-25

I arrived at Tonzi about 10:30 with Siyan and Ana. It was clear, sunny and hot. Everything is still green here, the trees more so than last time. The ground is damp but the road is dry except for the areas where puddles form.

Ana used the ASD again to collect a spectrum library.

I collected all the data. There were only partial images from the tower. Maybe I need to buy new CFM cards. I serviced the z-cams and replaced the clock batteries in z-cam 2 and 3. The battery in 2 was already dead and the one in 3 was at 2.8V. I replaced the battery in a-cam 1 some months ago.

Both the soil co2 and the Floor solar charge controllers are 30A but I could not see the serial numbers on the backs without serious disassembly. We could swap the soil CO2 one for a 15A version. On the soil co2 system, I dug the bottom of the larger solar panels out of the dirt and put them on a boardwalk. This made their angle slightly more flat and I adjusted the smaller ones to match.

I moved a fence post on the Floor site so the wires now miss the stump that is always touching the bottom wire.

Siyan did the standard fieldwork including leaf water potential.
