Summary: Regular data collection/cleaning, swapped LI-7700 for calibration, corrected LI-7550 time, deployed miniDOT at tower

East End
2017-11-10

We arrived at 13:20. It was mostly cloudy and cool. There was a light drizzle when we arrived.

Elke cleaned the EC and radiation sensors and refilled the wash reservoir. It was 2/3 full and had many wasps.

We turned on and deployed miniDOT sn 1219 at the tower ~13:45. We hung it off the north side of the tower so that it was submerged.

We swapped LI-7700: sn TG1-0155 came down, sn TG1-0357 went up. After the swap, I reset the box and made sure the LI-7700 was connected and logging.

The time on the LI-7550 was incorrect: when the time said 15:04, I changed it to 13:44.

I collected met, camera, and USB GHG data.

LI-7500 readings:
CO2 436.9 ppm
H2O 426.0 mmol/m3
T 16.4 C
P 102.1 kPa
SS 83.9 --> ?? after cleaning

LI7700 readings:
CH4 6.0 ppm --> 2.0 after cleaning --> 1.96 after swap
RSSI 0.2 --> 71 after cleaning --> 76 after swap

We left at 13:55.
