Summary: Trees fully leafed out, some road work done - maybe, standard data collection. All seems well.

Vaira
2025-04-10

Kuno, Mihkel and I arrived at about 15:30 PDT. It was warm and sunny with some wispy clouds. Everything is very green. It looks like there has been some heavy traffic on the road and maybe they tried to smooth out some of the deepest holes but not an overall improvement. The water hole was full but no puddles on the road - it rained last week. There is a scattering of flowers.

Kuno measured the well, but we confused the numbers a bit when I wrote it down.

Mihkel and I did the regular tower work collecting the flux, met, FD and camera data. All seemed well.
The 7500 read: 420.5ppm CO2, 593.6mmol/m3 H2O, 27.8C, 100.2kPa, 98.3SS

I forgot to bring the Jaz again - leaving it plugged in and charging makes it hard to remember to grab.

We left at about 16:00 PDT
