West Pond
2023-12-22

Arman and I arrived at 12:50 PST. It was a clear, sunny and mild first day of winter. We had about three days of rain this week. The inlet was not running. I had to climb down the scaffolding to read the staff gauge, but then didn’t write it down. It might have been 29cm.

I collected the flux, met and MiniDot data and the images from both cameras. Arman cleaned the eddy sensors and the radiometers. He also got the card from the Canon camera and restarted it after I got the files.
The 7500 read: 433.6ppm CO2, 611.8mmol/m3, 19.2C, 101.3kPa, 101.7SS
The 7700 read: 2.06ppm CH4, 49 RSSI – 89 after cleaning
We topped up the wash reservoir.

Looking at the data it seems we are losing power again at night. We are just trying to get this tower to the end of the year. We should probably just shut it down next time out.

We left at 13:15
