Development of Volcanic Ash Image Products Using MODIS Multi-Spectral Data

There is a need for polar orbiting satellite image products to augment the Geostationary Operational Environmental Satellite (GOES) imager in order to support the operational aviation volcanic ash warning system, since there will be some degradation in the volcanic ash detection capability of GOES beginning with GOES-12. The degradation is due to the temporary removal of a 12 micrometer infrared band that has proven its capability in detecting volcanic ash. This paper discusses the use of the Moderate Resolution Imaging Spectroradiometer (MODIS) to detect airborne volcanic ash clouds that present a hazard to aircraft. MODIS can be used to augment the reduced capability of GOES-12, until the 12 micrometer band is restored.
