Basic measurements of radiation at station Granite Island (2024-04)

The non-functioning tracker was replaced on April 25 (see also March data doi:10.1594/PANGAEA.967392). There is only global data through April 24. There are two missing days (April 25 and 26). All three components global direct and diffuse are present starting on April 27. Component sum residuals are good for mostly clear periods although they can be larger during times when the sky is varying. It is believed that this is caused by a difference in response time between the direct and global instruments.
