Summary: Regular data collection/cleaning, swapped 7500
| 2017-03-15 West Pond We arrived at 12:55. It was overcast and cool with a light breeze. The water level has come down a little bit, and there was some green tule coming up underneath the canopy. We drove only a bit onto the grassy road leading to the tower but did not drive all the way to the tower. We cleaned the EC and radiation sensors and collected met, USB GHG, and camera data. We swapped the Li-7500: sn 75H-2667 came down, sn 75H-2668 went up. LI7500 readings: CO2 413.7 umol/mol --> 408.5 after swap H2O 561.2 mmol/m3 --> 555.5 after swap (seems high?) T 20.8 Celsius --> 21.4 after swap P 101.5 kPa --> 101.5 after swap SS 106.8 -> 98.6 after swap LI7700 readings: CH4: 2.0 RSSI: 43.7 -> 81.5 after cleaning The new Li-7500 did not have a place to mount bird spikes. Kyle also put some split loom conduit around the net radiometer wires. We left at 13:20. |
