Bouldin Corn
2025-06-27

Kyle and I arrived at about 12:20 PDT. It was hot and sunny with a little breeze - not as scorching as I had feared. The gate was open and there was a guy cleaning up and digger south of the big ditch south of our field. The corn is more then head tall and looks very lush.

Kyle cleaned the sensors which was extra tough as the Arable had entrails draped all over it. I collected the met, flux, camera and Zcam data. I used the new laptop to collect the zcam data - these cameras are labeled BA unfortunately but otherwise seem good.
The 7500 read: 408.9ppm CO2, 820.5mmol/m3 H2O, 30.5C, 100.9kPa, 99.9SS - 104.0 after cleaning
The 7500 clean: 428.9ppm CO2, 642.5mmol/m3 H2O
The 7700 read: 2.04ppm CH4, 34.8RSSI - 80.6 after cleaning
We refilled the wash reservoir

Kyle did some quick veg heights but it is pretty uniform.

I set the Stardot clock, cleaned its window and fixed its focus. The FOV may have changed a little. I had some problems because the latop was initially using IP address 192.168.2.100 which the CR1000 also uses. I changed the laptop IP address to .9 and restarted the CR1000. Things work much better after that.

I removed the Purple Air unit sn 68c63acc07a9. It seems to have been only recording log files - not data files recently. There is a ground wire disconnected from the card writer and lots of spider webs inside. I'll clean it up and see.

We left at about 12:50 PDT
