Summary: Regular data collection/cleaning, hella wasps, changed eddy clock +1min

2021-09-03
East End

Carlos and I arrived at 14:30 PDT. It was hot and sunny with hazy skies. There were hella wasps flying around the tower and the sensors, but I didn’t see any specific nests or congregating areas. There were some ants in the 7550 box so I left them a few mothballs.

The staff gauge read 10cm.

I downloaded met (maybe), cam, and USB GHG data. The reservoir was mostly full; I topped it off. Carlos cleaned flux and rad sensors.

I changed the eddy clock +1min to match the laptop time. I reset the 7550 and checked that the clock still looked good.

LI-7500 readings:
CO2 398ppm
H2O 696ppm
T 29.9C
P 101.1kPa
SS 97 --> 99 after cleaning
LI7700 readings:
CH4 2.0
RSSI 60 --> 70+ after cleaning

We left at 14:55 PDT.

Back in the lab, I couldn't find any met file named "EE_met_20210903.dat". I either named it something else or forgot to download it.
