Summary: FD chamber retrieved.
| Arrived at 15:29. The weather was windy and sunny, and the sky was clear. Field was recently mowed; vegetation height and biomass samples not taken. Clipped Alfalfa around radiation and soil sensors. Joe brought FD chamber back to lab. Ada attempted spectral, received “TOO SATURATED†error. Elke completed soil respiration measurements. Collar 3 was screwed up for soil CO2. Removed chamber before measurements were done during cycle 2 I believe. Replaced chamber for cycle 3 again. Did not retake the measurement but moved on to chamber 4. Cleaned bugs out of soil CO2 box. Bring compressed air next time. Cleaned 7500 and radiation. LI7500 readings: CO2 399.3 H2O 0865 SS 99.4 -> 101.4 after cleaning T 33.9 P 101.0 Left at 16:05. |
