Twitchell Alfalfa: 2018-03-31 12:00:00 (DOY 90)
Author: Elke Eichelmann
Others: 25 students from SFSU

Summary: Field visit with students from SFSU and Andrew Oliphant

I came to the Delta with about 25 students from San Francisco State University and Andrew Oliphant as part of his class.

It was a nice day, very warm and calm, with only a few high thin wispy clouds.

We stopped at Twitchell Alfalfa around 12noon and had a look at the Eddy Flux tower and instruments. I hooked up the computer to show the students the readings for the 7500 and the sonic. I did not clean the instruments, since they still looked fairly clean.

CO2 was around 400ppm
H2O around 600 mmol/m3
SS around 104
I didn't write down any of the numbers, so this is from memory.

The solar panels were pretty dirty. We didn't have anything to clean them, but they should get a good clean next time we go out.
