Comment:
- Solar tracker turned off at ~1530GMT on 2025-02-06 (Feb. 6, 2025) in anticipation of heavy freezing spray. This was a preventative measure to protect the solar tracker from operating in heavy ice conditions.
- Solar tracker was turned back on at ~1400GMT on 2025-02-10 after the ice melt/sublimated from the solar tracker.
- Solar tracker turned off again at ~1530 GMT on 2025-02-28 for preventative reasons due to another forecasted heavy freezing spray weather event.
- Downwelling diffuse (DIF) and downwelling direct (DIR) data not available on the days the solar tracker was turned off. However, the component summation indicated a probable soiling of the DIR measurement. Therefore, all DIR was deleted starting 2025-02-07 through the end of the month. We believe SWD is OK, however, it is possible it was also soiled but to a lesser extent than the DIR. NOTE: The optics, including DIR and SWD, were cleaned 2025 March 13.
- Downwelling LW (LWD) and downwelling Global (SWD) are available the entire month.
- 2025 Feb. 11 had frost on the optics for some part of the morning hours and the SWD, DIR, DIF and LWD data were deleted.
- The ventilators (fans) were first known to have failed on 2025 Feb. 1. The fans were not fixed until the following month (Repair date: 2025 March 13).
