Summary: Regular data collection/cleaning, veg height measurements
| 2018-05-03 Twitchell Alfalfa We arrived at 10:45. It was windy, mostly clear, and sunny. The vegetation is still short, mostly grass and some nettle and alfalfa. We didn’t do LAI or spectral measurements or clip plot samples since we are taking this tower down soon and will miss most of the 2018 growing season. Dennis took veg height measurements. Kyle and Alex cleaned the radiation and flux sensors and the Arable sensor and solar panels. I collected met, soil CO2, camera, and USB GHG data. LI-7500 readings: CO2 396ppm H2O 550ppm T 16.5C P 102kPa SS 100 --> 101 after cleaning We left at 10:55. |
