Summary: Normal data collection, forced diffusion chamber working.
| Arrived: 11:20. Sunny, breezy, hazy in distance, clear sky. Alfalfa growing but not yet flowering. Collected USB GHG data; collected camera data; collected met data; collected rad data from CR10X; collected camera card: swapped CF card “TA†in and “SI†out; collected soil CO2: two TCs not working, STC12 and STC14=NAN. Did soil respiration measurements, did vegetation height and clip plots. Veg height (cm): 26, 38, 44, 23, 49, 32, 37, 36, 39, 24, 39, 44, 31, 39, 39, 31, 35, 37, 51, 45. Did not do spectral as the spectrometer is currently broken. Could hear the forced diffusion chamber working. Radiation sensors were very dirty, so we cleaned them.
