Summary: Regular data collection/cleaning, lost band on rotating shadow band (diffuse PAR) sensor

Sherman Wetland

We arrived at 9:00. It was sunny, clear, and calm for once. There are more tule coming in by the levee road. The rotating shadow band lost its band, and Joe wasn't able to immediately find it in the water underneath the sensor.

Kyle cleaned the precipitation bucket; it was totally plugged again. Joe cleaned the solar panels.

The wash reservoir was full. Kyle cleaned radiation and EC sensors.

I downloaded met, camera, and USB GHG data. The Licor data still has a messed-up header; uploading a master config file did not work to correct the headers.

LI-7500 readings:
CO2 426.3 --> 433 after cleaning
H2O 522.9 --> 467 after cleaning
T 20.6
P 101.5
SS 105.3 --> 106 after cleaning

LI7700 readings:
CH4 2.3
RSSI 40.3 --> 72 after cleaning

We left at 9:25.
