“…This includes both testing of individual parts of the model and the complete model. For example, the various DISORT solvers (Stamnes et al, 1988, and Table 1), the twostr solver (Kylling et al, 1995), and the POL-RADTRAN solver (Evans and Stephens, 1991) have been carefully tested against analytical as well as earlier model results by their developers. Over the years the tools within the libRadtran package have been thoroughly tested and compared against measurements and other models.…”

Abstract. The libRadtran software package is a suite of tools for radiative transfer calculations in the Earth's atmosphere. Its main tool is the uvspec program. It may be used to compute radiances, irradiances and actinic fluxes in the solar and terrestrial part of the spectrum. The design of uvspec allows simple problems to be easily solved using defaults and included data, hence making it suitable for educational purposes. At the same time the flexibility in how and what input may be specified makes it a powerful and versatile tool for research tasks. The uvspec tool and additional tools included with libRadtran are described and realistic examples of their use are given. The libRadtran software package is available from http://www.libradtran.org.

“…This sign criterion implies that negative (positive) values of DF are associated with an aerosol cooling (warming) effect. The solar fluxes with aerosols are measured as described before, whereas the aerosol-free irradiance is computed with the UVSPEC transfer model (Kylling et al 1995), following the methodology described by García et al (2006). The main concern in the simulation of the UVB radiation levels is to consider the total ozone content accurately.…”

The influence of mineral dust on ultraviolet energy transfer is studied for two different mineralogical origins. The aerosol radiative forcing DF and the forcing efficiency at the surface DF eff in the range 290-325 nm were estimated in ground-based stations affected by the Saharan and Asian deserts during the dusty seasons. UVB solar measurements were taken from the World Ozone and Ultraviolet Data Center S550 in the Asian area. These results may be used as a benchmark database for establishing aerosol corrections in UV satellite products or in global climate model estimations.

“…The clear sky UV fields of erythemal irradiance are calculated using the widely employed radiative transfer model UVSPEC (Kylling, 1995;Mayer and Kylling, 2005) which is based on the discrete ordinate method DISORT (Stamnes, 1989) and has been thoroughly validated against measurements (see references in Mayer and Kylling, 2000). The calculations are performed with total ozone as the only temporally varying input parameter whereas climatological parameters are used for all other atmospheric input data as well as surface albedo.…”

UV radiation below an Arctic vortex with severe ozone depletion

Abstract. The erythemally weighted (UV) irradiance below the severely depleted Arctic vortices in spring 1996 and 1997 were substantially elevated. On average the UV increased 36 and 33% relative to the 1979-1981 mean assuming clear skies from day 80-100 in 1996 and 1997, respectively. On clear sky days large regions of the Arctic experienced maximum UV increases exceeding 70 and 50% on single days in 1996 and 1997, respectively. A minor fraction of these increases are not anthropogenic and have a dynamical origin as seen by comparison to 1982, when hardly any ozone depletion is expected.
