Bouldin Corn

I arrived at 13:55 PST. It was an overcast and cool day. There were many ducks flying overhead, and 2 groups of hunters prepping at the duck club. The PurpleAir PM2.5 AQI was around 145. The Rio Vista AirNow station had an AQI of around 70. There was a new combo lock on the red gate. It was open so I was able to see the combo, which I’ve emailed to Joe and Tyler.

The field was even more flooded than last week, and the water was about shin height under the tower. It was 47cm (1.54’) from the top of the pipe to the water level. I changed the water level desiccant.

I downloaded met, camera, USB GHG data, and PA data. I changed the stardot camera time from 4/16/2020 to 12/16/2020. The time was correct. For some reason the stardot changed from Dec to April starting Dec 1.

I downloaded and cleared the FD chamber and moved its power wiring to the met box. I removed the 4 eos NFD chambers with their cables, ground stakes, clamps, and the grey box with the power screw terminal. I brought everything back to the lab so that Joe can download data, update the firmware, and install them at BA on Friday.

I cleaned the flux and rad sensors. I swapped the 7700 hat for one with a full set of spikes. There was a 7700 time sync error. I changed the eddy clock from 14:06 to 14:07 on the 7550 to match the laptop time. I reset the box, and the time sync error went away. I topped off the wash reservoir.

LI-7500 readings:
CO2 466ppm
H2O 470ppm
T 12.2C
P 101.6kPa
SS 102-->103 after cleaning
LI7700 readings:
CH4 2.5 after cleaning
RSSI 67-->86 after cleaning

I left at 15:05 PST.
