25. Tf Journal of the Aerological Observatory No 66 pp 47 56 2006 Diffuse Spectral UVB Observation using Brewer Spectrophotometer and New Automated Shadow Unit Mahito ITO Abstract A diffuse Brewer spectrophotometer for continuous operation through seasons was developed by replacing the previous manual shadowing device Ito 2005b with automated shadow unit controlled by computer In this paper the system of the automated shadow unit the setup procedures and the results of diffuse spectral UVB measurements carried out for six months from August 2005 to January 2006 are presented They are summarized as follows 1 The new diffuse system is comprised of black shade ball rotating frame automatic rotating unit binding frame and control PC set indoors The whole system was mounted on Brewer MKII 058 Shading of UV quartz dome is bimodal i e intermittent mode and continuous mode In the intermittent mode three sets of shade open time sequences can be programmed in an hour 2 Shadow effect of the rotating frame was confirmed to be negligible comparing with global Brewer MKII 052 on a clear sky day 3 Monthly maximum diffuse UVB irradiance ratio diffuse UVB global UVB of 0 908 was observed in October and the minimum of 0 845 in December during the observation period Average over six
