Relation between solar UVB and UV erythematic radiation at the surface
| Resumo: | The relation between solar UVB and UV erythematic irradiances, measured at the surface in Évora between August 2011 and December 2012, presents a small dispersion with RMSE and R2 values of 0.0022 W/m2 and 0.9989, respectively. This small dispersion was investigated through an analysis to aerosols, which revealed that this parameter has a very small contribution to the observed spread in the data. Thus, the equation expressing the relation between UVery and UVB was applied to a set of measured data, being obtained a BIAS of -0.0009 W/m2 and a RMSE of 0.0027 W/m2 from the comparison between UVery calculated, with the equation proposed, and the measured UVery. |
