  2. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. [1] Atmospheric temperature is a measure of temperature at different levels of the Earth's atmosphere.

  3. International Standard Atmosphere - Wikipedia

    en.wikipedia.org/wiki/International_Standard...

    The equation that relates the two altitudes are (where z is the geometric altitude, h is the geopotential altitude, and r 0 = 6,356,766 m in this model): = Note that the Lapse Rates cited in the table are given as °C per kilometer of geopotential altitude, not geometric altitude.

  4. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    In Australia, Visual Navigation Charts (VNCs) and Visual Terminal Charts (VTCs) usually indicate MEF information by use of bold elevation figures for each grid. Pilots are also required to ensure their planned route does not contravene the minimum flying altitude regulations contained in CAR 167. This restriction is normally 1000FT above ...

  5. Scale height - Wikipedia

    en.wikipedia.org/wiki/Scale_height

    The earth atmosphere's scale height is about 8.5 km, as can be confirmed from this diagram of air pressure p by altitude h: At an altitude of 0, 8.5, and 17 km, the pressure is about 1000, 370, and 140 hPa, respectively.

  6. Density altitude - Wikipedia

    en.wikipedia.org/wiki/Density_altitude

    Density Altitude Computation Chart [1] The density altitude is the altitude relative to standard atmospheric conditions at which the air density would be equal to the indicated air density at the place of observation. In other words, the density altitude is the air density given as a height above mean sea level.

  7. U.S. Standard Atmosphere - Wikipedia

    en.wikipedia.org/wiki/U.S._Standard_Atmosphere

    Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. [ 1 ] The U.S. Standard Atmosphere is a static atmospheric model of how the pressure , temperature , density , and viscosity of the Earth's atmosphere change ...

  8. List of mountain peaks by prominence - Wikipedia

    en.wikipedia.org/wiki/List_of_mountain_peaks_by...

    Height on the other hand simply means elevation of the summit above sea level. Regarding parents, the prominence parent of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col (mountain pass) of every peak that is more prominent than peak A. The parent is the peak whose ...

  9. Elevation - Wikipedia

    en.wikipedia.org/wiki/Elevation

    The term elevation is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Elevation histogram of the Earth's surface
