Summary: Regular data collection/cleaning, still low water level

2022-11-03
East End

Kanishka and I arrived at 15:30 PDT. It was mild and breezy. Still no water under the tower and the water level was below the staff gauge. I thought we had left one of the water jugs here last week but I don't see it today. I'll ask Joe to order more heavy-duty jugs.

I collected met, cam, and USB GHG data. Kanishka cleaned flux and rad sensors. I changed the eddy clock +30sec from 14:35:15 to 14:35:45 to match the laptop time and restarted logging afterwards. I also topped off the wash reservoir.

There were some teeny spikes in the 4-way radiometer data in the previous data download, but I didn't see any when checking today. I checked the 4-way mux screws; AG was a little loose on the first two 4-way channels so I tightened those but everything else seemed fine.

The 7500 read: 424ppm CO2, 255mol/m3 H2O, 20.0C, 102.1kPa, 102SS after cleaning
The 7700 read: 2.0ppm CH4, 78RSSI after cleaning

We left at 15:48 PDT.
