Basic measurements of radiation at station Granite Island (2025-01)

The solar tracker was deliberately turned off on 2025-01-02 at ~1530GMT due to anticipated heavy freezing spray that could cause heavy ice accumulation on BSRN instruments. It was turned on again on 2025-01-30 at ~1715 GMT after the ice melt/sublimated and after many overcast days. LWD and SWD available for the entire month, but DIR and DIF therefore not available from 2025-01-02 through 2025-01-29 and only partially on 2025-01-30. There were mostly overcast days in 2025 January.
