Space Environment (natural and artificial) — Earth Standard Atmosphere: 30 km to 120 km for Aerospace Use ISO/NP 21443

Scope

This document specifies the structure and properties of the Earth’s atmosphere from 30 km to 120 km
for aerospace use. It provides internationally accepted empirical models that specify the details of the
atmosphere. Additionally, it describes assimilative models widely used for meteorological forecasting. It
also refers to widely-accepted physical models providing insight into the physical and chemical
processes driving the response of the atmosphere.
