Summary: Regular data collection and cleaning, No Licor GHG data since 5/18

2017-05-25
West Pond

We arrived at 11:30. It was sunny, mostly clear, and calm.

The CO2 sensor is under water, so the funky numbers are not caused by the exposed sensor. Seems like we need to swap the sensor.

I collected the met, camera, and USB GHG data. Sam cleaned the radiation and EC sensors. I refilled the wash reservoir; it was mostly full.

There were only 2 days of camera data since the battery swap on 5/18, so there might still be power issues, or something wrong with the camera. We will swap this Canon camera out for a Stardot camera.

There was no Licor GHG data since 5/18 when we swapped the battery. Sam reset the interface and data was logging to USB after the reset.
