Moderate Resolution Imaging Spectroradiometer (MODIS) imagery are useful for identifying and tracking ash plumes from volcanic eruptions. The use of near real-time (NRT) satellite data for monitoring volcanic plumes is undergoing further developments to enable quantitative retrievals to be produced, which should enable a global capability for volcanic ash monitoring to be introduced.
Potentially useful data sets: MODIS Corrected Reflectance True Color, MODIS Aerosol, Atmospheric Infrared Sounder (AIRS) Visible/Near-IR Radiances and Brightness Temperatures and OMI Sulfur Dioxide (SO2) (total column).
