15. Complex refractive index of volcanic ash aerosol in the infrared, visible, and ultraviolet

Abstract

Very fine silicate-rich volcanic ash, generated by explosive volcanic eruptions, can efficiently be traced downwind with infrared satellite sounders. Their measurements can also be used to derive physical parameters, such as optical depths and effective radii. However, one of the key requirements for accurate retrievals is a good knowledge of the complex refractive index (CRI) of the ash under investigation. In the past, the vast majority of the studies used the CRIs from Pollack et al. [Icarus 19, 372 (1973)], which are based on measurements of thin slices of volcanic rock, and therefore are not representative for airborne volcanic ash particles. Here, we report measurements of the CRI of volcanic ash in suspension, generated from samples collected from recent high-impact eruptions in Chile (Puyehue-Cordón Caulle, Calbuco, and Chaitén), Iceland (Eyjafjallajökull and Grímsvötn), and Italy (Etna). The samples cover a wide range of SiO2 content (46% to 76%) as confirmed by an X-ray fluorescence analysis. In the experimental setup, volcanic ash was suspended in nitrogen through mechanical agitation. Extinction spectra were recorded in the infrared, visible, and ultraviolet spectral regions. The particle size distribution within the airflow was also recorded. An iterative algorithm allowed us to obtain fully consistent CRIs for the six samples, compatible with the observed extinction spectra and the Kramers–Krönig relations. While a good agreement is found with other recently reported CRIs in the UV/Vis, larger differences are found in the longwave infrared spectral region., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

During a volcanic eruption, a huge amount of aerosols are emitted into the atmosphere which can be transported over long distances. By absorbing and scattering radiation, volcanic ashes influence strongly the Earth radiative budget. These particles may also affect human health and for some intense events may perturb or interrupt air traffic. These interruptions are mainly due to a poor knowledge of optical, chemical and physical properties of volcanic ashes. Recent work1 showed the potential of using hyperspectral infrared spectrometer to detect and quantify volcanic ashes contained in the plume especially using IASI (Infrared Atmospheric Sounding Interferometer). However, in order to fully exploit IASI's spectra, a perfect knowledge of complex refractive index (CRI) of ashes is required.In that purpose, a new methodology2,3 based on laboratory measurements of volcanic ashes in suspension coupled with an optimal estimation method has been developed. This approach allow to get access to CRI of several volcanic ash samples with various chemical compositions. These specific CRI has been successfully used to retrieve physical parameters (effective radius and concentration) from two intense volcanic eruptions: Puyehue Cordon Caulle (Chile) and Grimsvötn (Iceland). A comparison with other studies4,5, using other CRI, has been performed and show a significant impact of CRI on physical parameters retrieved. 1 Clarisse, L., Prata, F., Lacour, J.
