Alfalfa
2016-06-24

I arrived about 2:20pm with Dennis. It was clear, sunny and hot with a light, variable breeze. There is water in the ditches and roads around the field. We drove the wheel track on the south edge of the field and then walked to the tower.

Dennis measured vegetation height.

The 7500 read: 386ppm CO2, 630mmol/m3 H2O, 31.0C, 101.4kPa, 100.2SS

There were not very many images from the Stardot camera on the CFM card. The camera was running. I swapped the card and restarted the data logger. It collected a set of images before we left. The Canon camera seemed to have a full set of images.

I collected data from the soil CO2 and radiometers.

I tried to connect to the Forced Diffusion chamber, but the software could not find the correct serial port. Iâ€™m still not sure the chamber is running. I will have to fiddle with the software in the lab for next time.

The met data did not get downloaded correctly. Double check next time.
