Summary: A break in the rain, Standard data collection, new laptop, swapped 7500 for calibration

I arrived at about 10:40 PDT (daylight savings again). It was clear and sunny with a cool breeze. Water is running and pooling everywhere still as it keeps raining. The grass is still growing slowly, mostly denser and not taller although the cows may be helping with that. If you look hard you might find some few leave on a tree.

I measured the well, collected the flux, met, camera and FD data. This was the first trip with a new laptop. I had to make some folder structures and install the FD software but otherwise it seemed fine. I swapped the IRGA from calibration, sn 75H-2176 came off and sn 75H-2514 went on.
2176 read: 427.5ppm CO2, 450.2mmol/m3 H2O, 15.9C, 99.8kPa, 102.7SS
2514 read: 428.8ppm CO2, 450.0mmol/m3 H2O, 15.7C, 99.8kPa, 101.5SS
I set the pressure coefficients, reset the clock and restarted the box.

Cows are putting pressure on the fence and the fence charger doesn’t seem to be working well. Need to test batteries and chargers in the lab for a swap.

Cows have also chewed on the cable for the Arable wind set – not sure if it is broken or not – need to check the data.

I did not go to the pond. I did spectra before I left – how do you flip the screen display?

I left at about 11:40
