Summary: Regular data collection, swapped sonic
| We arrived at 13:00. It was cloudy, cool, with a light breeze. There were three researchers from Sacramento State in the area measuring water flow near the tower. I collected met, camera, and GHG USB data. We cleaned the eddy flux and radiation sensors. I refilled the reservoir; it was 3/4 full. We switched out the Gill sonic anemometer: sn 120907 came down and sn 120908 went up. The new anemometer has upgraded firmware to correct for the W bug. We made sure the N-orientation of the anemometer was the same between the old and new sensor. We spent some time leveling the sonic by adding washers between the sonic base and metal mount. The 7500 read: CO2 428.9 ppm H2O 407.5 mmol/m3 T 8.5 C P 101.8 kPa SS 106.5 --> 106.9 after cleaning The 7700 read: CH4 2.17 ppm RSSI 52.7 --> 80.6 after cleaning We left at 13:45. |
