I arrived at 9:30. It was cold and mostly cloudy with the sun peeking through occasionally and a breeze making it feel colder. The field is still unflooded. The tower was restored four days ago after being knocked down by the wind.

The 7500 read: 446ppm CO2, 345mmol/m3 H2O, 6.82C, 102.0kPa, 102.4SS â€“ 102.7 after cleaning
The 7700 read: 2.48ppm CH4, 40.0RSSI â€“ 91.2 after cleaning
I did not check the wash reservoir but it was full just four days ago. There were some spider webs on the eddy equipment. . I didnâ€™t have a spare USB stick so I moved the eddy data off of the USB stick and replaced it.

I installed the new Purple Air sensor sn 84f3ebd5ffb1. It seemed to be working with PM2.5 readings in the 90s. We should think about mounting it so that moving the boardwalk doesnâ€™t yank it around.

No Phenocam images had been stored. I added an Ethernet switch powered from the CR1000 5V port to troubleshoot. Seems like a bad connection with the Ethernet cable to the camera. Reseating the cable and restarting the camera eventually solved the problem. I left the switch in place.

I collected the FD Chamber data and cleared their memories.

I left at 10:36
