| 3 | BMS | | Diffuse CM22 | 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. |
|---|
| 4 | BMS | | Diffuse CM22 | 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 CM22 #1 irradiance value was substituted with the BMS Diffuse CM22 #2 value, because the CM22 #1 tracker was un-shaded. |
