I arrived at about 10:40 PDT. It was cold and overcast but breaking up in to partly cloudy skies. The trees still only have a smattering of leaves – maybe 10-15%. It has rained again for the last couple of days but not much more rain in the current forecast. Some of the white popcorn flowers have bloomed. Water is still puddled and running everywhere. I saw the cow rancher drive past while I was at the Tower.

I measured the well and collected the met, flux, FD and camera data. All seemed well. The met and soilvue data I collected was for the same time period as last time since I forgot to change the collect by date to collect all since last collection.
The 7500 read: 422.2ppm CO2, 474.0mmol/m3 H2O, 11.3C, 99.5kPa, 101.6SS

The sensors were clean.

The fence charger battery box lid had blown off and the box was full of water and a drowned mouse. I dumped it out and put a couple holes in the bottom of the box. The fence seemed in functional shape.

I did spectra before I left for the pond – got lucky with a gap in the clouds providing steady light. The grass is very green and thick and starting to finally get a bit taller. Most of the field is still only about 5cm tall. But under the solar panels and in a spot where some battery acid had been spilled the grass was maybe 40cm tall but mostly bent over.

I had a small SUV and was able to drive to the pond getting out twice to inspect the road before proceeding. The pond is still heartily spilling over.

I left at about 11:45 PDT
