AB: The NASA Earth Observing System's Multi-angle Imaging SpectroRadiometer (MISR) and MODerate resolution Imaging Spectroradiometer (MODIS) have produced data records nearly eight years long, widely recognized and used due to their frequent, global coverage, radiometric stability, spatial resolution down to 250 m, and broad spectral and angular coverage. Aerosol products generated routinely from these data records include aerosol amount, and type. The MISR stereo-derived height product contains maps of cloud and aerosol source plume heights. Both statistical and case-by-case analyses illustrate the strengths of these products, but also reveal some limitations that must be considered, especially for large-scale, long-term aerosol climate studies. This presentation will review our current understanding of the strengths and limitations, illustrated with examples from a number of recent studies, and will highlight ongoing work aimed at further refining the MISR aerosol data record for climate applications.
