1BMSDirect CHP1-209/29/202312:40:0009/29/202313:55:00Due 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. CHP1 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.
2BMSDirect CHP1-212/01/202212:08:0012/01/202213:01:00Due 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.
3BMSDirect CHP1-211/22/202200:00:0011/23/202223:59:00Due 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.
4BMSDirect CHP108/22/202200:00:0008/25/202208:03:00Due 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.
5BMSDirect CHP108/21/202200:00:0008/21/202223:59:00Due 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).
6BMSDirect CHP105/18/202013:03:0012/15/202119:31:00DATA 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.
7BMSDirect CHP103/09/201906:25:0003/09/201913:41:00Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, The BMS Direct CHP1 #2 irradiance value was substituted with the BMS Direct CHP1 #1 value, because the CHP1 #2 tracker was not pointing at the sun during this time.
8BMSDirect CHP101/17/201707:15:0001/17/201708:56:00DATA CORRECTED on 1/18/2017: CHP1 #2 Data was corrected by substituting the CHP1 #1. Original problem: 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.
