Summary: Standard data collection, missed getting the phenocam photos, swapped the 7500 for calibration, Arduino RSB seemed okay - still running.

I arrived at about 12:15 PDT. I was late after a stop at BA in the Delta. It was mild and sunny with a cool wind from the west. The Bay Area got hit with smoke from wild fires to the north in the afternoon but no smoke here. The trees here are still green although I saw some yellow/brown along the road. The water hole is dry.

I did the standard data collection measuring the well, collecting the flux, met and FD data. I also swapped the 7500: sn 1594 came off and sn 0065 went on.
1594 read: 426.6ppm CO2, 599.6mmol/m3 H2O, 32.6C, 99.4kPa, 103.9SS
0065 read: 427.7ppm CO2, 590.6mmol/m3 H2O, 34.6C, 99.4kPa, 102.3SS
I updated the pressure coefficients, adjusted the clock to match the laptop and reset the 7550 box.

Seems I missed collecting the Phenocam data – should be okay until next time.

I also collected the data from the CR1000 connected to the prototype Arduino RSB diffuse PAR. It was still running, no hang up. I’ll have to look at the data more closely to see I can find any problems.

I cleaned the radiometers and did spectral measurements.

I left at about 13:00 PDT
