Summary: Regular data collection/cleaning, camera power was off

2017-05-10
West Pond

We arrived at 12:45. It was sunny and windy with high, thin clouds. The tule around the tower seem like they grew another meter in the last two weeks. Isabel and I were at WP while Elke and Joe took the truck to look at potential sites for the roving tower.

Isabel trimmed tules by the tower and in front of the solar panel.

I downloaded the met, USB GHG, and camera data. The camera was off and only had 2 days of photos. I emptied the card and restarted the camera. A "Charge the batteries" warning came on when I first turned the camera on, but the second time I turned the camera on, it stayed on. The minimum power at this site overnight can be <11 V, so this might be causing the camera to turn off.

I cleaned the EC and radiation sensors. The wash reservoir was mostly full so I did not refill it.

The fan was not working so I replaced it.
