Summary: Check on the LGR system - all well. Collected data from all instruments, soil chamber measurements

Alfalfa
2015-07-06

I arrived about 9:30 with Miguel. The field is very purple with flowers. The weather is mild and breezy.

The LGR system is running fine. I downloaded data from both the LGR and our system. The LGR inlet had slipped down the sonic stand to about 46cm below the sonic center. I moved it back up to 18cm (11”) below the sonic center and tied it better.

Miguel did soil chamber measurements.

I tried to set up the computestick to send data from our met CR1000. It could see the hot spot from inside the data logger box when the hot spot was set to boost its signal. I messed up the screen resolution for the little screen, but was able to use the LGR screen. I got it mostly setup, but decided not to install it and risk messing something up. Maybe after the LGR experiment is over I’ll get it setup for another few weeks.
