Basic measurements of radiation at station Granite Island (2025-02)

DOI

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).
