1 | BMS | | Diffuse SR25 | 04/08/2024 | 10:50:00 | 04/08/2024 | 11:25:00 | Cable was snagged on tracker that caused Diffuse CM22-2 and SR25 to become unshaded. However data was substituted with the CM22-1. |
2 | BMS | | Diffuse SR25 | 02/11/2024 | 06:01:00 | 02/11/2024 | 13:27:00 | Snow was built-up around the pyranometer dome creating very high diffuse irradiance. However data was substituded with the CM22-1 which was free of snow. |
3 | BMS | | Diffuse SR25 | 09/29/2023 | 12:40:00 | 09/29/2023 | 13:55:00 | Due to an NREL-wide power outage caused by Xcel Energy, 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. SR25 Data was corrected on 10/5/2023 by subsituting Diffuse with calibrated RSR Diffuse (calibrated by BMS for the 2 hours prior), then re-calculating Direct using BMS Global CMP22 and calibrated RSR Diffuse. |
4 | BMS | | Diffuse SR25 | 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 | | Diffuse SR25 | 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 | | Diffuse SR25 | 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 | | Diffuse SR25 | 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 | | Diffuse SR25 | 05/13/2020 | 11:58:00 | 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 | | Diffuse SR25 | 03/09/2019 | 06:25:00 | 03/09/2019 | 13:41:00 | Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, The BMS Diffuse SR25 irradiance value was substituted with the BMS Diffuse CM22 #2 value, because the SR25 tracker was un-shaded. |
