- Aerologist — A meteorologist specialized in aerology; a scientist or technician who deals with the study of the physical structure, thermodynamic properties, and dynamic phenomena within the upper layers of the Earth's atmosphere, utilizing data collected by radiosondes, pilot balloons, or weather radars.
- Aerological — Relating to aerology, concerning aerology; referring to the physical, dynamic, and thermodynamic study of the free atmosphere, especially the upper layers (upper troposphere, stratosphere). It applies to charts, data, or sounding stations.
- Aerology — A branch of meteorology that studies the physical properties, dynamic phenomena, and thermodynamic processes in the upper layers of the Earth's atmosphere (upper troposphere, stratosphere), beyond the direct influence of the ground; investigation is carried out through direct experimental methods, such as radiosondes, pilot balloons, weather rockets, and satellites.
- Aerometeorograph — A complex meteorological apparatus (recorder) specially designed to be mounted on board an airplane, aircraft meteorograph, or sounding balloon, used for the simultaneous graphic measurement and recording, on a rotating drum, of variations in barometric pressure, temperature, and humidity within the upper layers of the free atmosphere.
- Atmospheric sounding — An experimental method or technical procedure for investigating the upper layers of Earth's atmosphere by launching sounding balloons, meteorological rockets, or drones specially equipped with measuring instruments. This structural process enables the determination of the vertical profile of temperature, pressure, humidity, and wind speed, providing fundamental data for weather forecasting.
