Functionality
  • Allowed altitude inputs include any geometric or geopotential height in meters, kilometers, feet, or miles from 0 km to 1000 km
  • Returns kinetic and molecular-scale temperatures, pressure, density, gravitational acceleration, number density, speed of sound, dynamic and kinematic viscosities, and thermal conductivity coefficient
  • Automatically outputs variables in engineering unit system (SI or English) based on input height units
  • Independent of toolboxes other than base MATLAB (no symbolic)
Example Function Calls
Results = StandardAtmos(30000) % returns air properties as table for geometric altitude of 30,000 m
Results = StandardAtmos([40,50,60],'HeightUnit','mi') % returns air properties as table for geometric altitudes of 40, 50, and 60 mi
Results = StandardAtmos(20000,'UnitSystem','English') % returns air properties as table for geometric altitudes of 20,000 ft in English units
Results = StandardAtmos(84000,'ReferenceFrame','Geopotential') % returns air properties as table for geopotential altitude of 84,000 m
Results = StandardAtmos(1000,'HeightUnit','km','OutputFormat','Struct') % returns air properties as struct for geometric altitude of 1000 km
