The MODIS retrieval of aerosol optical depth (AOD) is an essential component of the 3D-AQS (3-Dimensional Air Quality System) collaborative project. In 3D-AQS, satellite, ground and lidar observations of aerosol are collected and displayed in real-time for state and local air quality applications. Although AOD is effective at displaying major aerosol events over the United States, large data gaps due to cloudiness, sun glint and high albedo can impede the interpretability of the AOD imagery. This research explores the application of "inpainting" techniques to fill in data gaps with interpolated values. Unlike conventional interpolation techniques, inpainting preserves edge boundaries in all directions, which minimizes the appearance of interpolation artifacts. Results will show the upper limits of the data gap size that can be effectively restored with inpainting, as well as the relative accuracy of inpainted values.
