On 17 and 18 March 2022 a Sahara dust event caused inconsistent readings of global and direct irradiance. These meaurements were omitted until cleaning on the 18th. Diffuse and downward longwave irradiance may also have been affected until cleaning but these measurements were left in. Because of maintenaince on 21-23 March 2022, air temperature and relative humidity were taken from alternative but high quality instruments close by the usual set up. Relative humidity has been calculated from air temperature and dew point temperature.
