1	BMS		Diffuse CM22 (unit 2)	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 Diffuse CM22-2 and SR25 to become unshaded. However data was substituted with the CM22-1.
2	BMS		Diffuse CM22 (unit 2)	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.
3	BMS		Diffuse CM22 (unit 2)	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.
4	BMS		Diffuse CM22 (unit 2)	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-1, sNIP, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, CM22-2, PIR. CM22 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.
5	BMS		Diffuse CM22 (unit 2)	08/22/2023	13:24:00	08/22/2023	15:46:00	Due to BMS south sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-1, sNIP, MS-57, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, CM22-2, PIR. However automatic substitution was enabled for the CHP1-1, sNIP, 8-48, and CM22-2.
6	BMS		Diffuse CM22 (unit 2)	08/21/2022	05:21:00	08/21/2022	11:15:00	Due to BMS south sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-1, sNIP, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, CM22-2, PIR. Since the middle sci-tec was down (due to collision with south scitec); data was corrected on 9/14/2022 by subsituting Diffuse 8-48 and CM22-2 with RSR Diffuse, then recalating Direct CHP1-1 and sNIP using BMS Global CMP22 and RSR Diffuse.
7	BMS		Diffuse CM22 (unit 2)	08/20/2022	11:56:00	08/20/2022	23:59:00	Due to BMS south sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-1, sNIP, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, CM22-2, PIR. However automatic substitution was enabled for the CHP1-1, 8-48, and CM22-2.
8	BMS		Diffuse CM22 (unit 2)	06/22/2022	16:53:00	06/23/2022	07:17:00	Due to BMS south sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-1, sNIP, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, CM22-2, PIR. However automatic data substitution was enable for the CHP1-1, 8-48, and CM22-2.
9	BMS		Diffuse CM22 (unit 2)	06/18/2020	07:11:00	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.
