An instrument that automatically records atmospheric conditions like temperature, pressure, and humidity at different altitudes during flight.
From 'aero-' (air) + 'meteoro-' (weather) + 'graph' (recording instrument). Developed in late 19th and early 20th centuries as scientists needed to gather atmospheric data from altitude.
Early aerometeorographs were brilliant inventions—they recorded data mechanically on rotating drums, revealing that the atmosphere had layers with completely different temperatures, a discovery that seemed impossible from ground observation.
