I arrived about 1:00pm with Patty. It was clear, sunny and warm with a strong breeze. The weeds in the field looked trampled by cows. There was a group from UC Davis there doing inventory measurements. The same folks I saw at Tonzi on Tuesday.

The computer wasnâ€™t collecting the met data because Cove had to set up the Loggernet setting last time. I completed the scheduled collection settings and saw the data collected but did not download it.

The LGR read: 13:05, 22.49C, 132.5Torr, 14.71usec, 10Hz, 1.883ppm CH4. Pressure was adjusted to 148.5Torr.

The 7500 read: 16.2mmol/m3 CO2, 704mmol/m3 H2O, 101.45kPa, 28.17C, 248diag

We did a tipping bucket test. This is an inch bucket and the total should have been 25.4mm. The total was 23.876. The difference was 1.524mm at 0.254mm per tip â€“ short by 6 tips. We turned the screws one full turn CW. The data was deleted from the data file.

There were a ton of wasps and a huge next in the main CR10X box as Cove reported. I opened the box and many of the wasps dispersed. I discovered they were entering the box through a quarter inch round hole in the bottom â€“ they just barely fit through the hole. I closed the door and plugged the hole with putty.

I collected the camera images that were missed last time do to wasp activity.

Patty did moisture point, veg height, spectral and well depth measurements.

Veg Height (cm): Tape measure from ground to top of plant
60, 27, 15, 20, 50, 60, 50, 60, 80, 50, 70, 90, 80, 68, 79, 40, 15, 25, 20, 50, avg = 50.5, stdev = 23.8
