Updated 22 May 2014

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.
