1BMSDiffuse SR2504/08/202410:50:0004/08/202411:25:00Cable was snagged on tracker that caused Diffuse CM22-2 and SR25 to become unshaded. However data was substituted with the CM22-1.
2BMSDiffuse SR2502/11/202406:01:0002/11/202413:27:00Snow 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.
3BMSDiffuse SR2509/29/202312:40:0009/29/202313:55:00Due 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.
4BMSDiffuse SR2512/01/202212:08:0012/01/202213:01:00Due 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.
5BMSDiffuse SR2511/22/202200:00:0011/23/202223:59:00Due 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.
6BMSDiffuse SR2508/22/202200:00:0008/25/202208:03:00Due 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.
7BMSDiffuse SR2508/21/202200:00:0008/21/202223:59:00Due 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).
8BMSDiffuse SR2505/13/202011:58:0012/15/202119:31:00DATA 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.
9BMSDiffuse SR2503/09/201906:25:0003/09/201913:41:00Due 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.
