Summary: Regular data collection, Tower still out of the field, Rice has sprouted

Arrived at 9:20. Sunny, windy, mostly clear skies, but hazy in the distance. Rice is up. Sprouts 3 or 4 cm tall can be seen in rows. Field is still dry and tower is out of the field.

Filled the LI7700 wash water reservoir, but it was still almost full. Cleaned the LI7500 and LI7700, which was really dusty.

Collected USB GHG data, collected met data from 23x. One soil heat flux plate and one thermocouple on profile 2 not working: SHF2 = -INF, SoilT2 04 = -INF

Joe came by later in the day to collect the camera card pictures. The new Camera is still tricky to operate.

The cable on the water pressure sensor is brittle and cracking. Maybe that is the reason why it has been giving some weird data lately? Look into that once the field is flooded and the sensor is deployed again.

LI7500 readings:
CO2 384.1
H2O 770.1
T 18.71
P 102.00
SS 80.93 -> 86.15 after cleaning
LI7700 readings:
CH4: 1.93 -> 1.92 after cleaning
RSSI: 33.7 -> 64.7 after cleaning
