Summary: Regular data collection/cleaning, swapped 7500

2017-03-15
East End

We arrived at 12:35. It was overcast and cool with a light breeze. There are some green tule and cattails coming up through the wetland (but not as much as at Mayberry). The water level seems low. There is is lots of cattail fluff everywhere.

We refilled the wash reservoir; it was half empty. The precip funnel looks clean.

Kyle cleaned the EC and radiation sensors. I collected the met, USB GHG, and camera data.

We swapped Li-7500: sn 75H-2669 came down, sn 75H-2514 went up. We loaded the new config file and updated the pressure coefficients.

LI7500 readings:
CO2 436.37 umol/mol --> 437.6 after swap
H2O 476.5 mmol/m3 --> 607.3 after swap (seems high?)
T 20.0 Celsius --> 19.5 after swap
P 101.8 kPa --> 101.9 after swap
SS 79.2 -> 98.3 after swap

LI7700 readings:
CH4: 2.02
RSSI: 44.0 -> 88.6 after cleaning

We left at 12:50.
