Bouldin Corn

Robert and I arrived around 11:55 PDT. The corn is still on the field; it has mostly dried out and maybe 10% of the plant is still green. It was sunny, windy, and smelled smoky. I checked our PurpleAir sensor and its AQI was about 100-115. The smoky smell seemed to dissipate while we were there, or maybe our noses just got used to it.

I downloaded met, cam, USB GHG, PA, and IRT data. Robert cleaned flux and rad sensors. The 7700 heater was already on winter hours, 18:00 to 08:00. The heaters prevent condensation from forming, so I extend its hours in the winter given the higher humidity and cooler temperatures. Guess I never changed this one back to summer hours.

The 7500 read: 413ppm CO2, 473mmol/m3 H2O, 27.2C, 101.3kPa, 86SS--88 after cleaning
The 7700 read: 2.04ppm CH4, 48RSSI--75 after cleaning

We left at 12:10 PDT. Seems like there’s been more traffic on Hwy 12 this year than in the past. Sometimes we have to wait a few minutes for a break in the traffic to merge on.
