Summary: Recent rain, grass under trees, went to the pond, cows around

Vaira
2019-09-25

Siyan and I arrived at 10:00. It was clear sunny and hot. There was some rain Monday and Wednesday of last week. Usually the first rains leave muddy streaks on the instruments and solar panels but I didnâ€™t notice that. And there was grass coming up in under many of the trees and along the banks of the stream from the pond. So maybe it rained pretty hard â€“ hard enough to wash the sensors clean.

I collected the data. The CO2 was reading pretty high but the 7500 seemed clean.
The 7500 read: 418.7ppm CO2, 648.5mmol/m3 H2O, 30.6C, 98.9kPa, 95.2SS

The radiation sensors were clean.

Siyan did soil moisture, clip plots and the well reading.

We went to the pond. The pond level was 14.48ft. Cows had been walking along the edge of the water and kicking the water pressure conduit. It still seemed intact and I piled some rocks around it to protect it.
