Observing Popocatepetl's Volcanic Ash Clouds Using MODIS Infrared Data (Abstract Only)

Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery offers a synoptic perspective of volcanic emissions and atmospheric interactions, which can be useful for hazard mitigation. MODIS images were collected for a period of increased activity of the Popocatepetl volcano in Mexico, during December 2000 - January 2001. Popocatepetl volcano is a tropical volcano with persistent and significant sulfur dioxide emissions and volcanic ash that are hazardous to the large population that lives near the volcano. Mexico's major international airport is located about 55 km northwest of Popocatepetl volcano, in Mexico City. The airport sees about 800 flights a day, and 20 million passengers pass through the airport every year. One particular image from MODIS during December 2000 - January 2001 displays four large volcanic eruptions that have dispersed volcanic ash clouds over a large are of Mexico. The results of the information from MODIS complement ground-based measurements, which are not able to measure large scale volcanic ash eruptions into the atmosphere. These results offer a possible solution for the amount of time it would take for a significant volcanic ash cloud to get to Mexico City from the Popocatepetl volcano.
