Summary: Regular data collection/cleaning, storms coming later this week

East End

Arman and I arrived at 13:30 PST. It was cool, mostly overcast with some weak sunlight, and breezier than the morning sites. We had some rain last week and storms coming in tomorrow and Friday. There were some sleepy wasps in the box that I exported. The staff gauge read 49cm.

I forgot to measure the surface water conductivity.

Arman cleaned flux and rad sensors and refilled the wash reservoir. He cleaned a little detritus out of the rain bucket. I downloaded met, cam, and USB GHG data. PARin looks ok recently—no nighttime spikes. I changed the eddy clock -2:30min from 13:50 to 13:47:30 PST to match the laptop time and restarted logging.

The 7500 read: 427ppm CO2, 376mmol/m3 H2O, 15.1C, 101.8kPa, 94SS—96 after cleaning
The 7700 read: 2.3ppm CH4, 32RSSI - 76 after cleaning

I started adding small wooden screws (1/2” #6) to the wooden backing board but it was taking longer than I hoped. Maybe I should try shorter or #4 screws? We still had half our sites to go for the day, so I left the box of screws in the enclosure for next time.

We left at 14:05 PST. We removed the upper boardwalk for storm prep.
