Atmosphere and wind models: the US Standard Atmosphere 1976, ISA offsets, custom soundings, wind profiles and turbulence.

Guide: Atmosphere, Wind and Turbulence: the models, their sources, how well they are validated and what they leave out.

  • ussa76: the 1976 standard from −5 to 86 km, with temperature offsets and launch-site anchoring.
  • moist: saturation vapour pressure and humid-air density and speed of sound.
  • profile: atmospheres from soundings and forecasts, and WMO geopotential heights.
  • wind: constant, power-law, logarithmic and layered mean winds.
  • dryden: seeded Dryden turbulence.

Every model is queried with geometric height above mean sea level; the flight engine converts from its ellipsoidal heights first. Samples report whether a model extrapolated.

Modules§

air
The state of the air at a point, and the Atmosphere trait every atmosphere model implements.
dryden
Seeded Dryden turbulence: the spectra, MIL-F-8785C parameters, a generator that is exact for any step length, and a precomputed gust field.
error
Error types for the atmosphere and wind models.
moist
Moist air: saturation vapour pressure, and the density and speed of sound of humid air.
profile
Custom atmospheres from soundings or forecasts: temperature, pressure, humidity and wind at levels, interpolated in height, with the offset standard atmosphere beyond them.
ussa76
The U.S. Standard Atmosphere, 1976, from −5 km to 86 km geometric altitude, with an optional temperature offset and sea-level pressure.
wind
Mean wind models: constant, power law, logarithmic law and tabulated layers.
