| Abstract | The March 2009 eruption of Mt. Redoubt created the potential for major problems for aviation due to the dispersion of volcanic ash. Mt. Redoubt, located 110 km west-southwest of Alaska Airlines hub Anchorage, last erupted in 1990 and caused an estimated $101 million cost to the aviation industry (Waythomas, 1998). It is important to assess the impacts on aviation so that valuable information may be obtained and used in developing better warning systems and handling situations associated with these impacts. A study was performed to (1) determine the altitude of SO2 dispersion through analysis of synoptic meteorological conditions and satellite imagery and (2) investigate the reported impacts on aviation from the volcanic ash dispersion. To assess the altitude of SO2 dispersion, volcanic ash was tracked using OMI SO2 column measurements. The OMI satellite images were assimilated with CALIPSO backscatter profiles, geopotential height plots, and HYSPLIT forward model trajectories. To investigate the impacts on aviation, reports from airports and Volcanic Ash Advisories were also reviewed. A complex dispersion of volcanic ash resulted from the eruption of Mt. Redoubt. The altitudes of ash dispersion were estimated on |
