| RH & Temp | |||||
| 2016-05-24 | L2310736 | HMP60 | Installed | RH & Temp | Installed on the Sherman Wetland tower at the initial set up of the site. |
| 2017-12-18 | L2310736 | HMP60 | Removed | RH & Temp | Removed from Sherman Wetland for 24hour side-by-side comparison at Twitchell Alfalfa |
| 2017-12-19 | L2310736 | HMP60 | Removed | RH & Temp | Removed from the HMP inter-comparison at Twitchell Alfalfa and returned to Sherman Wetland |
| 2018-08-07 | L2310736 | HMP60 | Removed | RH & Temp | Removed from SW because it has been reading too low. It was replaced with HMP45 sn W0730036. |
| 2020-09-10 | R0360206 | HMP155 | Installed | RH & Temp Test_A | Added to the railing near the radiation boom in a ventilated solar shield to compare the new globe thermometers to. |
| 2020-11-12 | R0360206 | HMP155 | Removed | Removed from SW and brought back to the lab because the comparison has ended. This reference sensor will be moved to WP next. | |
| 2018-08-23 | T2130005 | HMP45AC | Installed | RH & Temp | Installed at SW to replace the other HMP45 with a too short cable. Mounted in the original location. 1% slope in T and 6% slope in RH from TA inter-comparison. |
| 2019-01-24 | T2130005 | HMP45AC | Removed | RH & Temp | Brought back to the lab from SW for inspection b/c of data drops/spikes. It was replaced by sn W0730036. |
| 2018-08-07 | W0730036 | HMP45AC | Installed | RH & Temp | Installed at SW to replace HMP60 sn L2310736. The HMP60 was reading numbers lower than reasonable. |
| 2018-08-23 | W0730036 | HMP45AC | Removed | RH & Temp | Removed from SW because its cable was to short to allow it to be mounted in the correct place. |
| 2019-01-24 | W0730036 | HMP45AC | Installed | RH & Temp | Installed at SW to replace T2130005, which was brought back to the lab for inspection. |
| 2021-09-02 | W0730036 | HMP45AC | Moved | RH & Temp | Moved from SW to GT with the decomissioning of SW and the beginning of GT |
