Summary: Regular data collection/cleaning, wash reservoir still leaking--needs work

2023-04-25
East End

Robert and I arrived at 13:15 PDT. It was warm and sunny with some cirrus clouds in the sky and a gusty breeze. The lake by the gas pad that we’ve been driving through for the past few months has finally dried up. Some cattails are starting to peek up in front of the tower. Some bunches of tules by the road are super green.

The staff gauge read 56cm. The reservoir was empty; Robert refilled it. We still need to fix this leak; I’ve tried changing the filter but that didn’t help.

I downloaded met, cam, and USB GHG data. I changed the eddy clock +30sec around 12:29 PST to match the laptop time and restarted logging. Robert cleaned flux and rad sensors.

The 7500 read: 420ppm CO2, 290mmol/m3 H2O, 29.1C, 101.1kPa, 99SS – 101 after cleaning
The 7700 read: 1.97ppm CH4, 35RSSI -- 83after cleaning

We left at 13:30 PDT.
