Extract

This paper studies not only the shadow of shade by the sun, but also the incident ultraviolet radiation from the sky. The spectral distribution of ultraviolet radiance from the sky has been measured for three years. Erythema is abnormal skin redness. The erythematic action on it is multiplied by the measurement data and CIE erythematic action spectrum. The levels of erythema action on sky radiance are represented by the points based on space density in the chart. The chart is called ”UV Shade Chart.” It can be used to estimate ultraviolet exposure in outdoor space or under shade which is expected to be useful for blocking ultraviolet radiation.
