Stratospheric aerosol layer in 2011-2018 as retrieved from ground-based twilight sky spectral photometry above Tbilisi, Georgia.
Abstract
Aerosol extinction profiles in the upper troposphere - lower stratosphere were retrieved from ground-based measurements of twilight sky brightnesses at 780 nm. The measurements were carried out using a CCDcamera with a grating spectrometer. The retrieval algorithm was based on a fully spherical Monte Carlo radiative transfer code Siro used as a forward model. The measurements covered the period 2011-2018. The aerosol cloud passed above Georgia, South Caucasus in summer 2011 after the Nabro eruption (Eritrea). Nabro aerosol declined during autumn - winter 2011.
