In a study published in Remote Sensing, researchers introduced a novel absorbing aerosol index (AAI) retrieval algorithm based on an environmental trace gases monitoring instrument (EMI). EMI AAI algorithm could efficiently detect large aerosol events to reconstruct the spatial variability of ultraviolet-absorbing aerosols.
