Summary: Regular data collection, redeployed forerunner dissolved CO2 probe, swapped LI7500

Arrived at 12:30. It was sunny and clear with a light breeze. The wetland is dead. We ran into Timmy and another farm guy out at the site. They were planting cottonwood trees along the east side of the road at approximately 25m increments. The trees are tiny right now but this could be a problem in a few years when they get bigger. Need to watch out for shading and wind distortion effects.

Refilled wash reservoir, it was half full. Cleaned radiation sensors and EC instruments. Cleaned solar panels.
Swapped LI7500 head sn 75H-2514 came down, sn 75H-2669 was installed.
Collected USB GHG data, collected met data and camera images through remote desktop interface, all looks good. Joe tried to adjust the connection settings for the scheduled daily data collection. Should be working now.
Deployed dissolved CO2 forerunner 8% probe (sn ???).
LI7500 readings:
Sn 2514 -> sn 2669
CO2 453.53 -> 464.56 umol/mol
H2O 469.5 -> 394.2 mmol/m3
T 15.03 -> 15.01 Celsius
P 101.87 -> 101.87 kPa
SS 100.78 -> 100.55

LI7700 readings:
CH4: 2.74
RSSI: 39.5 -> 83.5 after cleaning
