Summary: Regular data collection/cleaning, windy day, wetland looking nice and green

2021-04-27
Sherman Wetland

I arrived at 15:55 PDT. It was windy and warm. There were a few sprinkles of rain a few days ago on Sunday, but that might be the last of the rain for this season. The wetland looks pretty much all green, and the tules are starting to grow back into the boardwalk. I climbed down and scrubbed the staff gauge, which read 82 cm.

I downloaded met, camera, and USB GHG data. There was a 7700 time sync error that seemed ok after checking the clocks and resetting the box. This site still needs a 7550 firmware upgrade--next time. I cleaned the flux and rad sensors and topped off the wash reservoir. The radiometers were pretty clean when I arrived.

I put on waders and retrieved the desiccant jar that had fallen off the boardwalk into the water during the last site visit. Some water had leaked it but the jar was still floating. The desiccant should still be good after oven drying.
