Summary: Wet road, heat flux plate found out of soil again, broke meter stick
| We arrived at 15:30. There was a light breeze and a cloudless sky. The road to the tower was wet the whole way so we parked and hiked in. The alfalfa is tall and flowering and smelling great. I think this is my favorite site. Mad measured veg height and cleaned the radiation sensors which she noted were very dirty. Kathleen measured LAI. I collected data and stepped on the meter stick (by accident-opps). I noticed the same heat flux plate from last week was pulled out of the ground (sn 6342). I reburied at 2cm near the tower. This needs to be re-installed properly. 7500 CO2: 390.83 umol/mol (394.58 after cleaning) H2O: 720.1 mmol/m3 (763.7 after cleaning) SS: 93.85% (94.81 after cleaning) Pressure: 100.89 kPa Temperature: 32.47ËšC SOS: 353.1 m s-1 Met: OK |
