Lacis, A.A., B.E. Carlson, and J.E. Hansen, 2000: Retrieval of atmospheric NO₂, O₃, aerosol optical depth, effective radius and variance information from SAGE II multi-spectral extinction measurements. Appl. Math. Comput., 116, 133-151, doi:10.1016/S0096-3003(99)00200-3.

The direct-beam spectral extinction of solar radiation contains information on atmospheric composition in a form that is essentially free from the data analysis complexities that often arise from multiple scattering. Ground based Multi-Filter Shadowband Radiometer (MFRSR) measurements provide such information for the vertical atmospheric column path, while solar occultation measurements from a satellite platform provide horizontal slices through the atmosphere. We describe application of a Multi-Spectral Atmospheric Column Extinctin (MACE) analysis technique that we developed to analyze MSFSR data to occultation measurements made by Stratospheric Aerosol and Gas Experiment (SAGE II). For analysis, we select the 1985 Nevaqdo del Ruiz volcanic eruption period to retrieve atmospheric profiles of ozone and NO₂, and changes in the stratospheric aerosol size and optical depth. The time evolution of volcanic aerosols serves as a passive tracer to study stratospheric dynamics, and changes to particle size put constraints on the sulfur chemistry modeling of volcanic aerosols.
