1 | BMS | | Diffuse 8-48 | 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. |
2 | BMS | | Diffuse 8-48 | 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. 8-48 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. |
3 | BMS | | Diffuse 8-48 | 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. |
4 | BMS | | Diffuse 8-48 | 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. |
5 | BMS | | Diffuse 8-48 | 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. |
6 | BMS | | Diffuse 8-48 | 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. |
7 | BMS | | Diffuse 8-48 | 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. |
8 | BMS | | Diffuse 8-48 | 12/28/2013 | 11:55:00 | 12/28/2013 | 15:59:00 | Due to a scheduled NREL power outage, to upgrade campus electrical infrastructure, The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, PSP, PIR. The South Sci-Tec tracker for these instruments are protected by UPS, however the battery depleted at 11:55 MST (the power outage started at 6:46 MST) |
9 | BMS | | Diffuse 8-48 | 12/21/2013 | 10:30:00 | 12/21/2013 | 16:22:00 | Due to a scheduled NREL power outage, to upgrade campus electrical infrastructure, The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, CUVA2, CUVB2, TUVR; and the following instruments were un-shaded: Diffuse 8-48, PSP, PIR. The South Sci-Tec tracker for these instruments are protected by UPS, however the battery depleted at 10:30 MST (the power outage started at 7:00 MST). Data for the Direct 8-48 was replaced with data calculated from the SRRL BMS Global CM22 and the SRRL Irradiance Inc RSR Direct Normal on 5/14/2014. |
10 | BMS | | Diffuse 8-48 | 09/06/2013 | 14:13:00 | 09/06/2013 | 15:00:00 | SRRL BMS ventilators were cleaned on Sept 6, 2013. Due to prolonged un-shading of the Diffuse 8-48 and PSP, the data from 14:13 through 15:00 MST was corrected using data from the Diffuse CM22. |
11 | BMS | | Diffuse 8-48 | 03/02/2013 | 13:06:00 | 03/02/2013 | 18:24:00 | Due to a scheduled NREL power outage, to upgrade campus power capacity, The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, NIP #1, LI-201, NIP RG780, CUVA2, CUVB2, TWC; and the following instruments were un-shaded: Diffuse 8-48, PSP, CM22, CUV4, PIR, CG4. The Sci-Tec tracker for these instruments are protected by UPS, however the battery depleted at 13:06 MST (the power outage started at 8:06 MST). Data for the 8-48 was reconstructed on March 5, using the diffuse measurement from the SRRL RSR2, which uses a LICOR LI-200 s/n PY69225. |
12 | BMS | | Diffuse 8-48 | 05/07/2011 | 05:55:00 | 05/09/2011 | 07:58:00 | There was a planned power outage for SRRL construction activities that started at 5:18 MST. Unfortunately, the backup generator provided to SRRL was providing bad power to the UPS powering the Sci-Tec trackers, therefore the UPS failed at 5:55 MST. Unfortunately, when normal AC power was restored at 11:45 MST, the Sci-Tec trackers had lost all their configuration due to UPS cycling on and off during the outage, therefore were not tracking. The tracker settings were restored on May 9 at 7:58 MST. The SRRL BMS Diffuse was not shaded during this time, however data for the 8-48 was reconstructed on May 16, using the diffuse measurement from the SRRL RSR2, which uses a LICOR LI-200 s/n PY69225. |
13 | BMS | | Diffuse 8-48 | 05/27/2010 | 18:00:00 | 05/28/2010 | 12:15:00 | Due to improper mounting of the replacement CH1 s/n 080033 the Sci-tec tracker was not tracking properly due to collision with the CH1 against tracker. The following BMS instruments were not pointing at the sun: Direct CH1, NIP2, CUVA2, & CUVB2 and the following instruments were unshaded: 8-48, PSP, PIR. The data was later corrected on June 30, 2011, by replacing the 8-48 data with the BMS Diffuse CM22 during this time. |
14 | BMS | 32331 | Diffuse 8-48 | 02/25/2010 | 10:50:00 | 02/25/2010 | 11:04:00 | The 8-48 signal was reading low due to intermittent signal cable problem between patch panel and multiplexer. The 8-48 channel was relocated from J-Box Ch. 3-0 (Mux Ch. 18) to J-Box Ch. 3-3 (Mux Ch. 21). This should solve the problem permanently. |
15 | BMS | 32331 | Diffuse 8-48 | 02/20/2010 | 08:48:00 | 02/22/2010 | 08:49:00 | The 8-48 signal is reading very low or negative due to unknown signal cable problem between patch panel and multiplexer. The data was later corrected on June 30, 2011, by replacing the 8-48 data with the BMS Diffuse CM22 during this time. |
16 | BMS | 32331 | Diffuse 8-48 | 02/14/2010 | 00:00:00 | 02/16/2010 | 08:10:00 | The 8-48 signal is reading very low on Feb. 14 and negative on the days that follow. A screw was tightened on the multiplexer. The data was later corrected on June 30, 2011, by replacing the 8-48 data with the BMS Diffuse CM22 during this time. |
