Summary: Regular data collection/cleaning, changed picam code back to FWB b1.8 r1.8

East End

Ari and I arrived at 12:50 PST. It was sunny, clear, and windy. It is still dry under the tower here and the water level was below the staff gauge. The wetland is mostly brown or yellow.

I downloaded met, cam, and USB GHG data. I downloaded the miniDOT data and swapped desiccant for the miniDOT and water level sensor. I changed the eddy clock +20sec around 12:59 PST and restarted logging. Ari cleaned flux and rad sensors; she reported SWin and LWin sensors were dusty before cleaning.

The wash reservoir was almost empty; we refilled it. I think the spray/spin should be ok since the RSSI was 61 when we arrived. Ari didn't notice anything especially dirty about the 7700.

After downloading the picam photos, I logged in via WinSCP to update its software. The picam is currently running the “FWB Sun” software where it takes two photos, one with AWB and one with FWB Sun. I added “_sun” to the name of the current version so its new file name is “go-raspberry-pi-timelapse_sun”.

I’m changing it today back to the previous version “FWB R1.8 B1.8” so it takes one AWB photo and one FWB photo where red gain=1.8 and blue gain=1.8. I changed the filename from “go-raspberry-pi-timelapse_fwbr18b18” to “go-raspberry-pi-timelapse” and restarted the picam. I had to reenter the file name prefix (EE_picam_) and check the box to skip nighttime images. I save the settings and restarted the picam again. After restart, all settings and the preview photo looks ok.

The 7500 read: 422ppm CO2, 293mol/m3 H2O, 19.2C, 101.6kPa, 99--103SS after cleaning
The 7700 read: 2.0ppm CH4, 61--84RSSI after cleaning

We left at 13:10 PST.
