Summary: Regular data collection/cleaning, calibrate 7700, camera was off and no photos on camera card

West Pond

Ari and I arrived at 10:55 PDT. It was hot and muggy at the tower, surrounded by plants. The water level has gone down and was just below the platform. The staff gauge read 82cm. Some of the tree branches along the roads have been trimmed, and Ari got out of the car to push some of the larger wood off the side of the road.

We calibrated LI-7700 sn TG1-0155, which looked fine. The optics RH was 3% so I left the desiccant as is (sensor came from factory recently which probably explains the super dry optics RH).

I downloaded met and USB GHG data. I changed the eddy clock +2min from 10:29:40 to 10:31:20.

The camera was off when we arrived and there were no photos on the camera card. Ari made sure the camera was started correctly with the countdown showing. Might be a loose power connection somewhere?

I downloaded miniDOT data and swapped its desiccant. I didn’t have enough loose, blue desiccant in the jar so I didn’t swap the water level desiccant this time.

There were ants in the met box; we left them some mothballs.

The 7500 read: 383ppm CO2, 803mmol/m3 H2O, 30.8C, 101.1kPa, 84SS – 102 after cleaning
The 7700 read: 2.1ppm CH4, 39RSSI – 90 after cleaning

We left at 11:35 PDT.
