Emissions Calculation

Description

This atmosphere calculator determines the atmospheric temperature, pressure, air density and other parameters for a given altitude using the US Standard Atmosphere 1976 (USSA) model. The U.S. Standard Atmosphere,1976 is an idealized, steady-state representation of the earth’s atmosphere from the surface to 1000 km. The model is based on existing international standards and is largely consistent in methodology with the International Standard Atmosphere (ISA). The equations used are adopted by the United States Committee on Extension to the Standard Atmosphere (COESA), which represented 29 U.S. scientific, governmental, military and engineering organizations. The U.S. Standard Atmosphere model represents the Earth’s atmosphere pressure, temperature, density and viscosity distributions at various altitudes.
Values at mean sea level (MSL):
·Pressure of 101.325 kPa MSL.
·Temperature of +15 °C at MSL.

Insert the desired altitude in meters and press the "Calculate" button to obtain results.
