Summary: Regular data collection/cleaning, changed eddy clocks +2min, willows need to be trimmed

2021-04-15
West Pond

I arrived at 14:25 PDT. The Twitchell gate was open and there were several large trucks going back and forth along the main gravel road. It was breezy, sunny, and mild. More green reeds are coming out, but the wetland is still overall brown. The willows by the tower levee road have leafed out in full force. They could use a trim next time. The staff gauge read 58 cm. The inlet was off.

I downloaded met, camera, USB GHG, and miniDOT data. I cleaned flux and rad sensors. The incoming radiometers were a little muddy. I topped off the wash reservoir.

I changed the eddy clock from 13:29 to 13:31 to match the laptop time and reset the box. All the 7550 settings looked fine and I double-checked that the 7700 was connected.

LI-7500 readings:
CO2 415ppm
H2O 291ppm
T 24.5C
P 101.5kPa
SS 96--> 98
LI7700 readings:
CH4 2.0ppm
RSSI 55--> 80 after cleaning

I left at 14:50 PDT.
