Summary: Regular data collection/cleaning, download zcam data

I arrived at the field around 9:27 PDT, it was breezy but getting hot. There was someone working on the gate when I arrived so I had to wait a few minutes before getting in. The corns are getting tall, the ditch on the side of the field was dry.

I downloaded the MET data (5min and 30min) and checked them. Some dips were seen in soil and PAR data, but those can be cleaned easily. There was around 8sec time difference, and I synced the logger time to the laptop time.

I swapped the card for NL115. After putting the card in, the station status was "Card OK", but the status light was solid red. I called Daphne, ejected the card and put it back in, and it worked.

Then I connected to the Picam, the zcam works. I started downloading the data as I move on to the flux data.

I downloaded the USB GHG data and checked the ambient conditions:
- The 7500 read: 410ppm CO2, 519mmol/m3 H2O, 25.9C, 101.5kPa
- The 7700 read: 1.9ppm CH4

The RSSI was ~30 and SS was ~98.5. I went up to clean the MET and flux sensors. After cleaning the RSSI was ~80.9 and SS was ~101.2.

I left around 10:30 PDT.
