Kuno and I arrived at about 15:15 PST. It had been cold and foggy most of the day but just lifted a little before we arrived. There are puddles on the road and water in the water hole from recent rains. The trees a bare and the grass has sprouted but probably won't grow much until it gets warmer. There were a bunch of mama and baby cows around.

The solar panels were a bit ajar - more evidence that there was some heavy wind here. I straightened them out but they could use some new stakes at the bottom where the old wooden stakes have rotted away.

I collected the met, flux, FD and camera data. Kuno measured the well including taking a water sample to test with the handheld salinity meter which read near zero. We also moved the Licor 7550 box from the vertical post facing west to the angled leg to the north. I'm hoping this will reduce the solar load on the box and the temperature sensor on the bottom of the box.
The 7500 read: 437.5ppm CO2, 489.0mmol/m3 H2O, 16.7C, 100.6kPa, 99.3SS

We went to the pond. The water level is still low but has come up a little.

We left at about 16:00 PST
