barometrischer

Barometrischer is the attributive form of the German adjective barometrisch, describing phenomena, measurements or instruments that relate to a barometer or to atmospheric air pressure. The term is common in meteorology, aviation, navigation and related sciences to denote pressure readings and pressure-dependent processes.

Etymology and usage: The word derives from the barometer, which in turn comes from French baromètre and ultimately from Greek baros (weight) and metron (measure). In technical language barometrischer Druck, barometrische Messung oder barometrischer Höhenmesser are standard compounds used to refer to pressure measurements, barometric pressure readings, and height determination based on air pressure.

Contexts and applications: In meteorology and climatology, barometrische Größen describe atmospheric pressure and its variations with weather systems. Barometrische Höhenmessung (barometric altimetry) determines altitude by measuring pressure changes, an approach used in aviation, mountaineering and some surveying practices. In navigation and geodesy, barometric data help calibrate instruments and support altitude reporting when other sensors are unavailable.

Historical note: The barometer, developed in the 17th century by Evangelista Torricelli, made possible quantitative pressure measurements. Standard sea-level pressure is 1013.25 hPa, a reference frequently encountered in barometrischen Messungen.

In German-language texts, barometrischer is a working descriptor for pressure-related phenomena tied to the barometer and atmospheric conditions, and is distinguished from terms referring to non-barometric pressure regimes.
