Summary: Regular data collection/cleaning

Bouldin Corn

We arrived at 9:20. It was chilly, overcast, windy/gusty.

Sam cleaned the radiation and EC sensors and checked the wash reservoir (it was full). I downloaded the met and USB GHG data. There is no camera data to collect yet.

LI7500 readings:
CO2 368.9 umol/mol
H2O 616.6 mmol/m3
T 15.2 Celsius
P 101.7 kPa
SS 85.2 -> 86.7 after cleaning

LI7700 readings:
CH4: 2.0
RSSI: 64.8 -> 77.0 after cleaning

We left at 9:35. From Bouldin Corn, we drove straight (south) for about 1 mile along the dirt road until you hit a t-intersection. Turn left (east) and continue for 2 miles until you see the Bouldin Alfalfa site on the right. You can drive either on the right or left side of the ditch. If you drive on the left side of the ditch, there are several crossing points to get to the right side.

We used a rented trencher to dig a 12in deep trench from the northwest corner of the porch, just past the end of a north-south drainage ditch to the tower location. It crosses both roads at a diagonal. The power cable (two conductor #10 with ground UF-B direct burial cable) is in 3/4in plastic conduit at the bottom of the trench.
