“…Recent spectral measurements were evaluated only for partial eclipses or in the pre-umbra (Fabian et al, 2001;Aplin and Harrison, 2003). Shaw (1978) developed a greatly simplified radiative transfer model wherein sunlight diffuses into the umbra only by first-and second-order scattering processes.…”

Simulation of solar radiation during a total eclipse: a challenge for radiative transfer

Abstract.A solar eclipse is a rare but spectacular natural phenomenon and furthermore it is a challenge for radiative transfer modelling. Whereas a simple one-dimensional radiative transfer model with reduced solar irradiance at the top of the atmosphere can be used to calculate the brightness during partial eclipses a much more sophisticated model is required to calculate the brightness (i.e. the diffuse radiation) during the total eclipse. The reason is that radiation reaching a detector in the shadow gets there exclusively by horizontal transport of photons in a spherical shell atmosphere, which requires a three-dimensional radiative transfer model. In this study the first fully three-dimensional simulations for a solar eclipse are presented exemplified by the solar eclipse at 29 March 2006. Using a backward Monte Carlo model we calculated the diffuse radiation in the umbra and simulated the changing colours of the sky. Radiance and irradiance are decreased by 3 to 4 orders of magnitude, depending on wavelength. We found that aerosol has a comparatively small impact on the radiation in the umbra. We also estimated the contribution of the solar corona to the radiation under the umbra and found that it is negligible compared to the diffuse solar radiation in the wavelength region from 310 to 500 nm.

“…During the solar eclipse, several incidents can be observed, such as the changing color of the sky, the moving shadow, shadows bands, the Sun's chromospheres, the corona and its prominences, the diamond ring as well as planets and stars that suddenly become visible against the darkening sky. (Fabian, et al 2001) The solar eclipse also causes almost complete darkness for a shorter duration. (Nishanth, et al, 2011;Fabian, et al, 2001;Foken, et al, 2001) An illustration of phases occurring during the solar eclipse phenomenon is depicted in Figure 2.…”

“…In fact, when the solar eclipse occurs, the Sun is masked by the Moon and this causes the darkness for a shorter duration. (Fabian et al, 2001;Foken et al, 2001;Nishanth et al, 2011) The solar intensity, light spectrum, and UV irradiation decrease, (Fabian et al, 2001;Foken et al, 2001;Koepke et al, 2001;Zerefos et al, 2001;Nishanth et al, 2011) and this disturbs the light-dependent chemical reaction in the Earth, such as photosynthesis process. (Abram et al, 2000) Solar eclipse phenomenon has attracted researchers from various fields.…”

The present study investigated the photodecomposition of an organic material during the partial (88.76%) solar eclipse phenomenon of 9 March 2016 in Bandung, Indonesia. Curcumin and anatase titanium dioxide (TiO 2 ) particles were used as models of organic material and photocatalyst, respectively. The influence of the process parameters (i.e., curcumin concentration and the amount of TiO 2 ) on the photodecomposition process was also investigated. The results showed that the curcumin was decomposed along with the solar light irradiation time. During the solar eclipse, the photodecomposition rate is suddenly down. The partial solar eclipse provided a slower photodecomposition process than the process under sunny days (conducted on 8 and 10 March 2016). The concentration of curcumin and the amount of TiO 2 also have played an important role in the photodecomposition, in which the lower concentration of curcumin and the higher amount of TiO 2 have a correlation to the obtainment of higher photodecomposition rate.

“…Several solar radiation measurements during total eclipses have been carried out, mainly in the 1960s and 1970s (Sharp et al, 1971;Silverman and Mullen, 1975). Recent spectral measurements were evaluated for partial eclipses or before and after totality (Fabian et al, 2001;Aplin and Harrison, 2003). The effects of cloud formations on the solar radiation reaching the Earth's surface are complex.…”
