Stratospheric aerosol plays an important role in chemistry and climate. Space-based observations of their optical properties have been key elements of the study of the effects of major volcanic and extreme fire events. To aid users of SAGE III/ISS Level 2 aerosol data, the mission is releasing a Level 2 aerosol auxiliary product that identifies cloud-free observations using the method of Kovilakam et al. 2023 (https://doi.org/10.5194/amt-16-2709-2023). The algorithm is similar to that developed for the Global Space-based Stratospheric Aerosol Climatology (GloSSAC), in which SAGE III/ISS data plays a crucial role alongside other space-based measurements (asdc.larc.nasa.gov/project/GloSSAC ). The new Level 2 aerosol auxiliary product is released at the same cadence as the L2 solar products. For general ease of use, the results are grouped into monthly netcdf file.
