Summary: Installed new power line, heat flux plates, FR 2cm still giving strange readings
| Arrived at 11:28am. It was overcast and breezy. There were lots of sheep on the berm to the north of the field. Kyle cleaned the solar panels. He dug a new trench for the power line to the radiation sensors etc. 10cm deep. I wired in the 3 heat flux plates and Kyle buried them all near the tower (sn 6498, sn 6342, sn 6491). The 2cm Forerunner probe was reading 0mV we think due to a chewed cable. I replaced the cable but the new reading was 5000mV which is too high. May need a new probe too. It was too foggy for spectral and the veg height was too short for LAI (5cm). 7500 readings: CO2 = 401 ppm H2O = 432 mmol m-3 signal strength = 95.8% t = 16.9 C p = 101.9 sos = 342 m s-1 |
