| CR10X 3501 | 2019-09-27 | Lab none | Upgrade | Lab none | I upgraded the OS from v4 to v23. All seems well. The internal lithium battery is dead and needs to be replaced before deployment. |
| GP-001 GP20160096 | 2019-09-20 | Lab none | Tested | Lab none | Tested in the lab, and seems to be responding fine against another 1% probe. Not sure what the issue was in the field. However, the connection between the sensor and the screw connector is loose, so it should be sealed before re-deployment. |
| GP-001 GP20150109 | 2019-09-20 | Lab none | Tested | Lab none | Tested in the lab and still maxing out. This sensor should be sent back to the factory/disposed. |

| 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? |

See RT Report "Oxford Tract Radiometer Comparison - 06/2018" for details. I calculated a calibration factor of 12.8 uV/(W/m2), but there was a big difference from the calibration factor when the sensor was tested upside down (14.3 uV/(W/m2)), so more testing needed. |

See RT Report "Oxford Tract Radiometer Comparison - 06/2018" for details. I calculated a calibration factor of 12.7 uV/(W/m2), but more testing needs to be done because there was a large calibration difference when testing the sensor upside-down (15.4 uV/(W/m2)). |
