West Pond

Kuno, Camilo, and I arrived at 16:15. It was gray, cold, and cloudy. There was no standing water around the tower; the water level was 17 cm (soil level ~21 cm). I trimmed back the willow by the road/platform.

Kuno collected met, camera, and USB GHG data. Camilo cleaned the flux and rad sensors. We swapped the 7500 for calibration: sn 75H-2182 came down and sn 75H-2668 went up. Kuno uploaded a new configuration file, updated pressure coefficients, and reset the box.

LI-7500 readings (sn 75H-2182 --> sn 75H-2182 clean --> sn 75H-2668):
CO2 418ppm--> 420 --> 424
H2O 360ppm --> 350 --> 333
T 9.1C --> 9.2 --> 9.1
P 101.4kPa --> 101.3 --> 101.3
SS 86--> 86 --> 99.6

LI7700 readings:
CH4 2.3ppm
RSSI 38 --> 70? (forgot to write after cleaning)

On the way out, I turned the inlet all the way on, but it was still only dripping. I left it Â¾ open.

We left at 16:45.
