Ahead of the gap age, meteorologists infrequently paid specific consciousness to the peak areas above the tropopause. What was once recognized in regards to the top surroundings above approximately a hundred km got here primarily from ionospheric and geomagnetic study. The quarter in among, shortly often called the center surroundings, was once virtually terra incognita above the peak available through balloons. It was once area learn that allowed for the 1st time direct entry to center and higher atmospheric heights. approximately forty years in the past, Sidney Chapman coined a brand new observe 'aeronomy' to explain the research of those top areas. whilst requested concerning the distinction among aeronomy and meteorology, he allegedly responded: 'it is equal to among astronomy and astrology' . This light irony exhibits the popular prejudice of many ionospheric physicists and geomagneticians in these days towards meteorology as a descriptive instead of an actual technological know-how, inspite of the presence of such giants as Carl Rossby and Hans Ertel.
