| PAR Sensor | |||||
| 2023-08-29 | 010164 | PAR-LITE | Installed | none | Installed as part of the Arduino base RSB diffuse PAR mounted next to the BF3 |
| 2020-08-26 | 030381 | PAR-LITE | Installed | PAR Sensor Reflected Cal | Installed at Vaira in the reflected position for inter-comparison. This sensor will likely replace the old sensor. |
| 2020-09-16 | 030381 | PAR-LITE | Moved | PAR Sensor Reflected | Moved from the reflected cal position to the main reflected position. |
| 2020-08-26 | 040412 | PAR-LITE | Installed | PAR Sensor Incoming Cal | Installed at Vaira in the incoming position for inter-comparison. This sensor will likely replace the old sensor. |
| 2020-09-16 | 040412 | PAR-LITE | Moved | PAR Sensor Incoming | Moved from the incoming cal position to the main incoming position. |
| 2020-06-12 | 140455 | PQS 1 | Installed | PAR Sensor Incoming Cal | Installed on the Vaira Tower mounted in the incoming position for cross comparison and eventual swap of the old sensor on the tower for cable repair. |

| 2020-08-26 | 161073 | PQS 1 | Removed | PAR Sensor Incoming Cal | Removed from Vaira incoming after inter-comparison. |
| 2004-07-24 | 26/8 | BF3 | Installed | PAR Sensor Diffuse | This looks like a likely install date - major data logger rewiring, first data in the data base. |
| 2016-04-05 | 26/8 | BF3 | Maintenance | PAR Sensor Diffuse | Replaced the desiccant, some condensation in the dome. |
| 2021-03-17 | 26/8 | BF3 | Maintenance | PAR Sensor Diffuse | Replaced two packs of internal desiccant - a little bit of condensation in the dome. |
