Summary: Swapped 7500s, restarted Tower CO2 profile, FD chamber not working, fixed cow fences.

Siyan and I arrived at about 11am. It was clear, sunny and cool with a little breeze from the southwest. The ground is damp and there are some puddles in the road but the pond level didnâ€™t seem to change much. The grass and herbs have spouted and the grass is about 4cm high.

I installed the solenoid switching box for the co2 profile cal gasses and the LI-820 sn CGA-556. The system seemed to be running okay, but when I tried to calibrate, it seemed like there was a leak somewhere. The zero and span were noisy and did not quit reach the expected values. I tried tightening connectors but it still needs some testing. I left it running.

I swapped the Tower 7500
Off sn 75H-2182: 426.0ppm CO2, 514.7mmol/m3 H2O, 13.07C, 99.73kPa, 87.4SS
On sn 75H-2668: 428.9ppm CO2, 453.6mmol/m3 H2O, 13.3C, 99.72kPa, 101.3SS

And swapped the Floor 7500
Off sn 75H-2180: 412.9ppm CO2, 597.2mmol/m3 H2O, 15.29C, 99.76kPa, 95.3SS
On sn 1594: 426.7ppm CO2, 454.4mmol/m3 H2O, 15.21C, 99.75kPa, 101.6SS

Both showed big drops in H2O but I think the new values are better. I saved the configuration before uploading the new one just to be safe.

I collected the data from the FD chambers. Next time we should clear the data after collecting. The chamber in the Open location seems to have failed â€“ probably a bad pump as both CO2 concentrations were the same.

All the cow fences had broken wires. We fixed them and turned them on as there are some cows around.
