The Atmospheric Ozone Layer
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides oz

The extent to which wind shear presents a hazard to aircraft has been well documented in the last ten years. Since some wind shear can occur in otherwise relatively good weather, the most hazardous kind, a microburst, is associated with rain showers and thunderstorms even thought the parent storm may not be discernible. It was not until the early 1970's that the National Transportation Safety Board was able to obtain the level of data form flight recorders to quantify wind shear. This data beca
