UV Index - Daily Dose (Radiant Exposure) - Forecast:
This is the predicted erythemally effective daily dose for tomorrow.
The forecast is done for a horizontally oriented plane receiver by using the CIE action spectrum for the human erythema derived by McKinlay and Diffey (CIE 1987).
The core procedure is a fast spectral UV model, which is already validated by measurements of irradiance
(Schmalwieser et al. 2001)
and daily dose made at 4 continents
(Schmalwieser et al. 2005)
as well as by comparisons to other models
(Koepke et al. 1998, Schmalwieser et al. 2000).
A simple preparation scheme
(Schmalwieser et al. 2002)
is applied to total ozone measurements made by EPTOMS delivers appropriate TOC values for the next day.
