MODIS imagery are useful for identifying and tracking ash plumes from volcanic eruptions. The use of 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, AIRS Visible/Near-IR Radiances and Brightness Temperatures and OMI Sulfur Dioxide (SO2) (total column).
