Summary: Regular data collection/cleaning, swapped 7500 for calibration
| 2019-01-18 East Pond Dennis, Kuno, Camilo, Jiangong, and I arrived at 13:40. It was mild and mostly overcast. Some of the dead veg have been blown down. The water level was 61 cm. We refilled the wash reservoir (don’t write down how empty it was). Kuno cleaned the flux and rad sensors. I downloaded met, camera, and USB GHG data. We swapped the LI-7500 for calibration: sn 0035 came down and sn 0073 went up. One of the spikes in the 7500 spikes fell into the water, but we had a spare one in the truck, originally meant for BA. I uploaded a new configuration file, updated the pressure coefficients, and reset the box. There was a 7700 time sync error. I changed the 7700 to slave, reset the box, and this resolved the error. LI-7500 readings (sn 0035 --> sn 0073): CO2 390ppm --> 416 H2O 510ppm --> 434 T 17.9C --> 17.2 P 102.9kPa --> 102 SS 95--> 98 after swap LI7700 readings: CH4 1.96ppm RSSI 29 --> 83 after cleaning We left at 14:15. |
