FIELD NOTES
Weather:Sunny, clear skies and a bit windy
I refilled the methane sensor’s water reservoir from 40% remaining to full.
Sensors were cleaned without problems. However, the precipitation bucket was extremely dirty and clogged with feathers, bird droppings and food leftovers. Looks like a small bird was nesting there briefly. It was washed and cleaned as best as possible.
All data were downloaded without problems. The phenocam data were retrieved using the local network this time.
The field laptop seemed to be about 15 seconds ahead of the data logger, but upon inspecting the mobile phone’s time it seemed that it was the fault of the laptop for not being recently synced (data logger was agreeing better with UTC). No action was taken.
