Summary: Regular data collection, field flooded but bare, swapped LI7500
| Arrived at 11:40. It was sunny and mostly clear but really hazy on the horizon. There was no wind. The field was still flooded but bare. Refilled wash reservoir, was half empty. Cleaned GHG sensors. Collected USB GHG data, collected met data from CR1000. Swapped LI7500 head: sn 75H-2180 came down, sn 75H-2182 was installed. One of the soil HFPs (SHF3) reading had the opposite sign but same magnitude as the other two. We didn’t bring any rubber boots and didn’t want to put on wader for this so did not investigate further. The camera was running and we collected all pictures. The rain bucket looked clean. Water table at the well was 23cm above ground level. LI7500 readings: sn 2180 -> sn 2182 CO2 435.7 -> 441.5 umol/mol H2O 380.8 -> 359.8 mmol/m3 T 12.95 -> 13.66 Celsius P 102.38 -> 102.38 kPa SS 95.9 -> 85.09 LI7700 readings: CH4: 2.8 RSSI: 35 -> 70 after cleaning Left at 12:10. |
