Summary: Regular data collection/cleaning, installed stardot camera biomass samples (clip plots), vegetation height measurements, Licor soil co2 was not working
| 2017-10-26 Twitchell Alfalfa We arrived at 10:50. It was sunny and clear, but hazy on the horizon. We disturbed a burrowing owl while we drove through the field. It bobbed up and down indignantly. Joe cleaned the EC and radiation sensor and reinstalled the StarDot camera sn 0030F4D2148D (missing the sliding mount). Sam started Licor soil CO2 readings, but the instrument was not working (Sam - more details). Sam took 5 clip plot samples and I took veg height measurements. I downloaded met, soilCO2, camera, and USB GHG data. LI-7500 readings: CO2 449.8 ppm H2O 581.5 T 25.1 P 101.4 SS 96.1 --> 99.5 after cleaning We left at 11:20. |
