| 1 | BMS | | Direct DR02 | 04/21/2024 | 00:00:00 | 04/21/2024 | 23:59:00 | Tracker arm on one side of tracker was bumped out of position that caused Direct DR02 and DR20 to be off position and read near zero. Data should not be used. |
|---|
| 2 | BMS | | Direct DR02 | 04/08/2024 | 10:50:00 | 04/08/2024 | 11:25:00 | Cable was snagged on tracker that caused Direct DR02 and DR20 to be off position and read near zero. Data should not be used. |

| 4 | BMS | | Direct DR02 | 12/01/2022 | 12:08:00 | 12/01/2022 | 13:01:00 | Due to BMS middle sci-tec backup battery replacement (which requires soldering), The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, SR25, and CM22-1. |
|---|
| 5 | BMS | | Direct DR02 | 11/22/2022 | 00:00:00 | 11/23/2022 | 23:59:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not exactly pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were just barely shaded: Diffuse SR25, CM22-1, CG4. On 11/23/2022, 11/22/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker. Note that data on 11/23/2022 were automatically substituded at the logger during middle tracker replacement. |

| 6 | BMS | | Direct DR02 | 08/22/2022 | 00:00:00 | 08/25/2022 | 08:03:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, NIP, SR25, and CM22-1. |

| 7 | BMS | | Direct DR02 | 08/21/2022 | 00:00:00 | 08/21/2022 | 23:59:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. On 9/14/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker (which were also reconstucted). |
|---|
| 8 | BMS | | Direct DR02 | 05/18/2020 | 13:03:00 | 12/15/2021 | 19:31:00 | DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021. |
|---|
| 9 | BMS | | Direct DR02 | 03/09/2019 | 08:40:00 | 03/09/2019 | 13:01:00 | Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, The following BMS instruments were not pointing at the sun during this time: Direct NIP, LI-201, LI-190, NIP RG780, TWC, DR02; and the following instruments were un-shaded: CG4. |
|---|
| 10 | BMS | | Direct DR02 | 01/17/2017 | 07:15:00 | 01/17/2017 | 08:56:00 | Due to a tripped GFCI powering the Sci-Tec tracker, The following BMS instruments were not pointing at the sun during this time: Direct CHP1 #2, NIP, DR02, LI-201, LI-190, NIP RG780, TWC; and the following instruments were un-shaded: Diffuse CM22 #1, CMP11, CG4. |
