Atmospheric smoke and dust are hazards that impact human health and welfare. Level 2 (derived) aerosol observations from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the JPSS Program’s SNPP, NOAA-20, and NOAA-21 polar-orbiting satellites aid in detecting and tracking smoke and blowing dust. VIIRS products include aerosol optical depth (AOD), a quantitative measure of atmospheric aerosols, and aerosol detection product (ADP), a qualitative indicator of the relative intensity of smoke and dust aerosols. VIIRS AOD and ADP have daily global coverage over cloud-free regions with 750m spatial resolution. A brief overview of the AOD and ADP algorithms will be presented, along with validation results, to highlight the strengths and limitations of the products. Examples of VIIRS AOD and ADP for recent smoke and blowing dust events, with a focus on Alaska, will demonstrate the utility of the products for research and operational applications, and show how the products can complement VIIRS true color and dust RGB imagery.
