| 2018-11-28 | A000251 | Mark I | Installed | Weather Station A | Installed at BA to replace sn A000591, which will be sent back to Arable for inspection. |
| 2018-12-13 | A000251 | Mark I | Removed | Weather Station A | Brought back to the lab because it did not seem to be charging in the field. Seemed to charge up fine in the lab. |
| 2018-12-18 | A000251 | Mark I | Installed | Weather Station A | The Arable Mark was reinstalled after charging in the lab. |
| 2019-06-20 | A000251 | Mark I | Removed | Weather Station A | Removed for use elsewhere since there are two other units on the tower courtesy of Arable. |
| 2018-02-28 | A000591 | Mark I | Installed | Weather Station A | Installed on the top, south rail of the scaffolding, between the radiation boom and the precip bucket. I leveled the sensor, but it was not pointing N because I prioritized aiming the downward-facing sensors towards the alfalfa. I also set up the Arable’s auxillary solar panel between the Arable and the precip bucket. |
| 2018-11-02 | A000591 | Mark I | Notes | Weather Station A | Arable e-mailed to say sn A000591 which has a bad backup temperature sensor and requested we send it back. Not knowing what the exact source of the failure is, and having checked and found no similar behavior in any other device, they want to find out why. We planned to remove this Arable on 2018-10-04, but instead removed sn A000251 from BC and sent that Arable back to the factory. The Arable at BC was replaced by sn A001911. sn A000591 is still at BA for now. |
| 2018-11-28 | A000591 | Mark I | Removed | Weather Station A | Removed from BA and brought back to the lab. We will send this back to Arable b/c they noticed a faulty thermocouple. It was replaced by A000251. |
| 2019-04-25 | A001311 | Mark I | Installed | Weather Station B | Installed by Loreli and Mikaela from Arable for an inter-comparison experiment. |
| 2021-01-21 | A001311 | Mark I | Removed | Weather Station B | Removed from Bouldin Alfalfa as Mark I's are being phased out. Replaced by Mark II sn C006164. |
| 2022-11-18 | B301045 | Mark 3 | Installed | Weather Station B | Installed at BA main tower on the north side of the scaffolding. The solar panel is facing south and the sensors are facing north, above the met/IRT enclosures. |
| 2024-02-14 | B301045 | Mark 3 | Removed | Weather Station B | Removed from Bouldin Alfalfa. Replaced by sn D006812. |
| 2019-05-23 | C002469 | Mark II | Installed | Weather Station C | Installed on the southwest end of the scaffolding for inter-comparison with the existing Mark I unit and our tower data. The Mark I unit was also move from near the eddy equipment to the southwest railing. |
| 2020-04-17 | C002469 | Mark II | Removed | Weather Station C | Removed from Bouldin Alfalfa and replaced by sn C003240. The old one was a prototype and the new one is from the production run. |
| 2020-04-17 | C003240 | Mark II | Installed | Weather Station C | Installed at Bouldin Alfalfa to replace sn C002469. The old one was a prototype and the new one is from the production run. |
| 2022-10-18 | C003240 | Mark II | Removed | Weather Station C | Removed from BA (eastern position) because its T/RH sensor is broken. Brought back to the lab to ship back to Arable. It was replaced by sn C013311. |
| 2020-05-29 | C003751 | Mark II | Installed | Weather Station PL_S-A | Installed on an orange post about 40m northeast of the tower. This is part of the Planet Labs / Arable inter-comparison |
| 2021-06-16 | C003751 | Mark II | Removed | Weather Station PL_S-A | Removed as requested by Arable |
| 2020-05-29 | C003789 | Mark II | Installed | Weather Station PL_N-B | Installed on an orange post about 70m northeast of the tower. This is part of the Planet Labs / Arable inter-comparison |
| 2021-01-21 | C003789 | Mark II | Removed | Weather Station PL_N-B | Removed from the northwest Planet Labs location due to broken antenna caused by sheep |
| 2020-05-29 | C003800 | Mark II | Installed | Weather Station PL_N-A | Installed on an orange post about 70m northeast of the tower. This is part of the Planet Labs / Arable inter-comparison |
| 2021-01-21 | C003800 | Mark II | Removed | Weather Station PL_N-A | Removed from the northeast Planet Labs location due to broken antenna caused by sheep |
| 2020-05-29 | C003947 | Mark II | Installed | Weather Station PL_S-B | Installed on an orange post about 40m northeast of the tower. This is part of the Planet Labs / Arable inter-comparison |

| 2022-11-18 | C013433 | Mark II | Removed | Weather Station B | Removed from BA main tower (south side of scaffolding) since we don't need 3 Arables on one tower. We are installing a Mark 3 today and we already have a Mark II that is connected to the wind set and the Sentek soil moisture profile probe. |
| 2024-02-14 | D006812 | Mark 3 | Installed | Weather Station B | Installed at Bouldin Alfalfa to replace sn B301045 |
