Summary: Standard data collection, still a little green grass, went to the pond

Vaira
2021-05-19

Dennis and I arrived at about 10:45 PDT. It was clear sunny and mild with a cool breeze from the SSW. Itâ€™s actually greener here than I expected. The hills on the way up looked very brown, but there is still some green grass here. The water hole is about half full. A lot more dandelion tufts than usual I think and dead clover.

Dennis did soil moisture and the well reading.

I collected met, flux, camera and FD data. All looked well.
The 7500 read: 413.1ppm CO2, 295.0mmol/m3 H2O, 20.6C, 99.4kPa, 103.2SS

We went to the pond. Back in the lab looking at the data, the pond data logger has been losing data. Probably the battery is wearing out. Might try a lithium power pack.
