10000 mW/cm^2 would be 10 W/cm^2 which is 100 000 W/m^2 of UVB. Total solar radiation should be on the order of 1300 W/m^2 (it's nominally 1000 max here at 42N) at overhead sun, so 10x the power just in UVB makes zero sense.
I am at 42ish North (Massachusetts, US), and with a Davis UV sensor, the highest values I see are about 7. The US index talks about mid teens, but we are a less tropical place than you. The web page inexplicably presents numbers without units as if that is a reasonable thing to do. https://www.epa.gov/sunsafety/calculating-uv-index-0 Reading wikipedia, 18-19 seems higher than plausible https://en.wikipedia.org/wiki/Ultraviolet_index This also seems to argue against 19: https://www.who.int/uv/publications/en/UVIGuide.pdf but this seems to say it is plausible: https://niwa.co.nz/sites/niwa.co.nz/files/import/attachments/Liley_2.pdf I would look at values published by your national weather or health authorities and compare. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
