Validation of a radiative transfer model with measurements of UV radiation inside a commercial aircraft

A radiative transfer model for the determination of UV radiation on arbitrarily oriented surfaces is validated by spectral measurements taken directly on the inner surface of a cockpit window of an Airbus A321-231 during a flight from Frankfurt, Germany to M álaga, Spain on 23 August 2018. The simulations consider the UV spectral range from 290 to 400 nm and take into account both the measured spectral transmittance of a cockpit window as well as its construction-related orientation. Comparisons are performed for selected route segments with largely cloud-free conditions. The cruising level of the Airbus on these segments was nearly constant between 11.27 and 11.29 km. UV irradiance measurements at the cockpit window give values within a range of 19 and 26 W m −2 . The comparison of modelled and measured irradiances show a very good agreement, i.e. the relative differences between simulated and measured values range from −2.1% to +4.3%. In addition, horizontally and vert...
