Arman and I arrived at 14:10 PST. It was a clear, sunny and mild first day of winter. Our field is flooded. Charlotte called me this morning from LA saying that one of her analyzers had water in it. I got a key from her lab mate, Jeff, for two locks on a big chain around the box but didn’t have a key for the four locks on the edges. Fortunately the hasps had been put on so that their screws are exposed – a few minutes with a screw driver and we had the box open. I shut things down, removed a filter and dumped about a teaspoon of water out of it. Following instruction from Charlotte on the phone I put the filter back and restarted the system with everything just pulling air from inside the box to dry things out. Arman also pulled from the field chamber #12 which was almost under water. We reassembled the box – I left two pieces of tubing under the tarp on top of the box.

At the tower I collected the flux, met, camera, IRT and PA data. Arman cleaned the eddy sensors and radiometers.
The 7500 read: 440.6ppm CO2, 556.1mmol/m3 H2O, 20.6C, 101.3kPa, 100.9SS
The 7700 read: 2.06ppm CH4, 38RSSI – 78.7 after cleaning
We topped up the wash reservoir.

There have been a few power outages. Partly the duck club might be browning out the panel when combined with all of Charlotte’s stuff.

We left at 15:15 PST
