Summary: Standard data collection, still some leaves, added lower staff gauge to pond.

Vaira
2018-10-29

I arrived at about 1pm with Siyan and Remi from LBNL. It is still very dry but some of the trees here still have green leaves. There was a gusty wind from the west with high thin clouds.

I retested the tipping bucket and got 113/100 tips this time. Last time it was 22tips low and I adjusted the screws 3 turns CW. This time I adjusted the screws 1 turn CCW. Probably need to test again.

I collected the data.
The 7500 read: 414.6ppm CO2, 329.3mmol/m3 H2O, 100.0kPa, 27.7C, 98.3SS

Siyan did soil moisture and spectral.

We went to the pond. Siyan collected the data. The water level is about 4.5in below the last installed staff gauge. I had one more in the lab, so I waded in and installed the gauge that reads 10.16-13.52 ft. The water level was 13.2ft. There may be less than an inch error in the position.
