| GP-001 GP20160096 | 2019-09-18 | East End CO2 probe | Removed | Lab none | Removed from East Pond because it was railed high even in air. |
| GP-001 GP20140026 | 2019-09-18 | Lab none | Installed | West Pond CO2 Probe B | Reinstalled at the northwest corner of the scaffolding. The water level is low so it is sitting in a puddle for the time being. |
| Mark I A001911 | 2019-09-18 | Lab none | Installed | Sherman Wetland Weather Station | Reinstalled at new location on radiation boom pointing south. Plugged into tower power. |
| GP-001 GP20140026 | 2019-09-16 | Lab none | Tested | Lab none | Tested against 2 good sensors (1% and 2%) in the lab test chamber with atmospheric CO2 and with an exhalation. Seemed to respond similarly to the other sensors. This sensor has degraded threads, so you can't get the cable off. I will seal up the connection again. I'm not sure why it was maxing out in the field, but seems fine now. Maybe some condensation inside evaporated? |
