I arrive at about 15:00 PDT. It was mostly overcast and cool. Record rains a few days ago have thoroughly wet the ground. There were large puddles and running water in the road. The water hole was full and the pond was full to overflowing. There were lots of broad leave sprouts coming up and some grass. In places where the litter is not too heavy the ground was definitely tinged green. The biomass fence has made its annual move. Lots of cows with babies around.

At the tower all looked well. I collected the met, flux, phenocam, and FD data.
The 7500 read: 418.2ppm CO2, 457.8mmol/m3 H2O, 100.3kPa, 20.5C, 102.9SS

I retested the tipping bucket. I didnâ€™t have the lithium power pack because I left it at Tonzi to power the Road Well. But, the cables were long enough for me to put the CR23X on the boom next to the tipping bucket and power the pump from the 23X 12V ports. The bucket got 49/50 tips â€“ good enough.

I brought in the two solar panels, sn 020854E-6-03-02-06905 and sn 020854E-6-03-02-06862, that had been used for the soil CO2 24V power system. Iâ€™m hoping to use them to test Elkhorn Slough systems.

I took some spectra but the light was a little variable.

I left at about 16:30 PDT
