Summary: Regular data collection/cleaning, smog from the Central Valley

2024-12-04
East End

Carlos and I arrived at 10:30 PST. It was sunny, cool, and still. The horizon toward the Central Valley looked smoggy. The staff gauge read 51cm. We replaced the upper boardwalk on the tower that was removed last time for storm prep. The reservoir was almost empty; Carlos refilled it.

I downloaded met, cam, and USB GHG data. I downloaded the miniDOT data and swapped its desiccant. I measured surface water conductivity. Carlos cleaned flux and rad sensors and checked that the precip bucket funnel was clean.
Surface, 667uS, 5.7C

The 7500 read: 720ppm CO2, -160mmol/m3 H2O, 13.9C, 102.3kPa, 43SS (probably dew)
7500 cleaned read: 549ppm CO2, 561mmol/m3 H2O, 13.9C, 102.3kPa, 95SS
The 7700 read: 3.03ppm CH4, 26RSSI - 77 after cleaning

I still need to secure the dataloggers/mux to the wooden backing board.

We left at 10:50 PST.
