CIRA Atmosphere

atmospheric conditions to 2000km

You are now following this Submission

This is a class that implements the CIRA dry atmosphere to 2000km altitude using NRL's MSIS-E 2000. It calculates atmospheric components and their densities, temperature, pressure. This extends the implementation to calculate altitude gradients in temperature and densities. This atmosphere is responsive to solar flux (F10.7) and Ap index as well as seasonal variations.
