Summary: Dry and cold, talked to Dale, moved calkit PAR, standard data collection

Vaira
2022-02-23

I arrived at about 10:45 PST. Dale Vaira arrived shortly afterwards. Dale had open heart surgery in November but is up, driving and walking around on his own just three months later – amazing! Dale wanted to go over the pond level reporting forms one more time – I think we have it all straight now.

Still almost no rain and the roads are dry but really cold today. It’s sunny and clear but a stiff cold wind from the west. There were signs for chain requirements on Hwy 50 over the mountains. The grass looks good but still grazed down to the nubs. The ground surface is hard and dry though. I didn’t see any cows today.

I measured the well and collected the met, flux, FD and camera data. I collected the calkit data and moved the Ameriflux PAR sn 212225 from incoming to reflected.

The 7500 read:434.0ppm CO2, 256.5mmol/m3 H2O, 99.9kPa, 9.1C, 100.0SS

I did spectral measurements and went to the pond to collect the data.

I left at about 12:00
