East End

Alex, Kuno, Ariane, and I arrived at 11:45. It was a sunny and breezy day with blue skies. The wetland is about 20% green. The water level was 19 cm (lower than before).

The wash reservoir was nearly empty; we refilled it. Alex swapped the 7500 for calibration: sn 75H-2667 came off and sn 0035 went up. Ariane cleaned flux and rad sensors. Kuno downloaded met, camera, USB GHG, and miniDOT data. After the 7500 swap, we uploaded a new config file, updated the pressure coefficients, and reset the box.

LI-7500 readings (sn 75H-2667 --> sn 0035):
CO2 421ppm --> 433
H2O 597ppm --> 451
T 24.6C --> 24
P 101.5kPa --> 101.6
SS 100.4 --> 98

LI7700 readings:
CH4 2.01ppm
RSSI 43--> 80 after cleaning

We left at 12:15.
