West Pond: 2021-09-03 14:00:00 (DOY 246)

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

2021-09-03
West Pond

Carlos and I arrived at 14:00 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. The water level was below the soil surface, and with all the wasps around I did not climb down the scaffolding to get a closer look at the staff gauge. The plants were still looking good despite the low water levels.

I downloaded met, 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 406ppm
H2O 660ppm
T 29.7C
P 101.2kPa
SS 97 --> 98 after cleaning
LI7700 readings:
CH4 2.1
RSSI 67 --> 83 after cleaning

We left at 14:25 PDT.
