Abstract Biologically active solar Ultraviolet radiation is monitored in Kathmandu valley in Nepal (27.7°N, 85.5°E, 1350 m asl) using a multichannel broadband radiometer for the period of November 2004–March 2005. Result shows noontime one-hour average CIE weighted dose rate can reach up to 0.195 W m − 2 (UV index = 7.8 at solar zenith angle, SZA = 36.8°) for a cloud free sky. Radiative transfer calculations indicate that UV index around local noon can reach as high as 14 in a clear summer sky… CONTINUE READING
