  4. 4. Meteoric Aerosols in the Middle Atmosphere

    Författare :Linda Megner; Jörg Gumbel; Martin Ridal; Gary E. Thomas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meteoroid; meteor; nucleation; mesosphere; stratosphere; ablation; smoke; NLC; PMSE; PSC; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : This thesis concerns the fate of the meteoric smoke in the Middle Atmosphere, and its effect on ice phenomena such as noctilucent clouds (NLC) and polar stratospheric clouds (PSC). The potential role of NLC as tracer for mesospheric processes and variability, and as a tool for monitoring this remote and inaccessible region, has generated substantial interest within the scientific community.
