Kuno, Will and I arrived at about 14:40 PST. Will is along from Rob Rhew's lab to look at Tonzi. Everything is wet after about four days of rain but it is mostly sunny with fluffy white clouds today. Puddles and water running on the road, the water hole is full. The grass is about 10-15 cm tall but grazed pretty heavily.

Kuno did the well measurement, I was able to do spectral measurements without jiggering the reference value.

I collected FD, flux, met and camera data from the tower.
The 7500 read: 424.2ppm CO2, 380.9mmol/m3 H2O, 16.0C, 100.2kPa, 100.1SS

I changed the met program to update the RevBowen calculations again. I think it is correct now but may have had a factor of 1000 off before.

The solar panels had been blown askew again, I straighten them out. I put new desiccant in the BF3 which had some condensation in its dome.

We went to the pond - no trouble in the AWD SUV. The pond was full and actively over flowing. I was also surprised by the amount of water leaking through the dam. I collected the data. The conduit has come off the bottom of the box and the fitting is broken. It put it back in place but it probably needs more intervention. Adding data to the database, the last five days were missing. Maybe a full download next time will find the missing data.

We left at about 15:30 PST
