  3. 1992 Spurr Eruption Case Discussion

    27 Apr 2011 | Contributor(s):: William I Rose

    This lecture summarizes distal ash cloud observations via satellite and radar, along with information about meteorology and fallout, for the 1992 Crater Peak/Spurr eruptions. These small subplinian events produced significant fine and very fine ash fallouts that were sampled and measured. Even...

  4. Thunderstorms and Volcanic Clouds

    27 Apr 2011 | Contributor(s):: William I Rose

    There are many similarities between eruption clouds and common convective clouds which lead to thunderstorms. This lecture calls attention to the comparison.

  5. Reducing the threat to aviation from airborne volcanic ash

  6. Chaiten eruption observations, May 2008

    10 Feb 2011 | Contributor(s):: William I Rose

    A review of the Chaiten eruptions based mainly on satellite observations. This lecture was compiled in October 2009.

  7. Detecting volcanic ash from space

    08 Feb 2011 | Contributor(s):: William I Rose

    How satellites detect, map and measure volcanic ash in volcanic clouds. HYSPLIT and volcanic cloud satellite observations. Volcanic cloud stages. Infrared satellite detectors, split window. Evolution of volcanic clouds from space platforms.Rose, W I, G J S Bluth, D J Schneider, G G J Ernst, C M...

  8. Direct sampling of volcanic clouds

    08 Feb 2011 | Contributor(s):: William I Rose

    Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...
