摘要: [1] A McDonnell-Douglas DC-8 NASA research aircraft inadvertently flew into an airborne volcanic ash plume from the 26 February 2000 eruption of Hekla Volcano. Filter samples were compared with “normal use” and “pristine clean” filters using SEM, energy-dispersive x-ray spectrometer, Nicolet FTIR spectrophotometer analyses. These analyses confirm that encountered This result is supported by independent onboard heated aerosol observations at time encounter. The further demonstrate ambiguous nature dual band thermal IR (“split window”) method for detecting point view aviation safety. They also highlight utility in situ filter-based aerosols scientific purposes.
