East End
2015-07-20

I arrived about 10am with Ana. It was hot and humid with little to no wind. The plants are continuing to grow.

I checked the connections on the solar system and found only one screw that tighten up about a quarter turn.

Ana removed the older model sonic sn 000024 and 7500 sn 1594. We installed a newer sonic sn 124215 and 7500A sn 75H-2182 with box sn AIU-0397. I left the CR1000 that had been collecting the flux data in the box. It will be removed at some later date. The 7550 box seemed to have reverted to factory settings. I set its time zone to ETC/GMT+8 and made sure it was set to PST. I connected the 7700 to the box in software and the 7700 data were viewable in the 7550 interface, but I did not check the clock setting on the 7700. I had to choose the data columns to collect from the 7500 and 7700. I set the data collection rate of the box to 20Hz but forgot the check the rate on the 7700. I set the conversion factors and names on the analog channels on the box for the sonic. I forgot to bring one of our standard USB drives for the 7550 box. I had an 8GB drive that I use. I put my files in a folder called Joe, and there were 4GB free. This seemed to work in the 7550 box, but should be swapped out next time.

Just after we arrived the 7700 did an auto cleaning of its mirror.
When we left the 7700 read: 1.947ppm CH4, 79.3RSSI
The 7500 read: 399.4ppm CO2, 896.0mmol/m3 H2O, 85.2SS, 29.3C, 101.5kPa

The autocam seemed to be off. I restarted it.
