Summary: Regular data collection, LI7550 pressure coefficients missing
| Arrived at 14:35. It was clear, and sunny but cool and there was a light breeze. The water level was right at the surface where the well was (could see the water around the well base). We collected USB GHG data and collected met data. Swapped CF camera card. There were a few ants in the datalogger box so we left some mothballs in there. Rain gauge seemed clean although there was still lots of bird poop all over the place. We cleaned the radiation and eddy flux sensors. Refilled the wash reservoir, it was a 3/4 full. The pressure reading at the LI7550 (sn 1569) box is low. It looks like the coefficients weren’t changed last time the LI7500 head was replaced. When we wanted to change the coefficients we realized they were not taped inside the box (probably the reason why they weren’t changed last time). Need to find out what those coefficients are and write them down in the box. Need to change the coefficients next time in the field (this site also needs a new LI7500 so when the head is replaced make sure to input new coefficients). LI7500 readings: CO2 441.5 umol/mol H2O 373.4 mmol/m3 T 14.8 Celsius P 100.2 kPa SS 101.1 -> 102 after cleaning LI7700 readings: CH4: 2.52 RSSI: 47.5 -> 82.7 after cleaning Left at 14:50 |
