Overview
========

The :model:`WSF_JACCHIA_ROBERTS_ATMOSPHERE` provides an atmosphere model that
models the exospheric temperature profile, with dependence on solar
and geomagnetic activity. The density is then obtained for various altitude
zones. For details, see  Vallado's *Fundamentals of Astrodynamics and
Application*, Fourth Edition, Appendix B.

Commands
========

.. command:: solar_flux <real-value>

   Set the 10.7 cm solar flux, in units of :math:`10^{-22} \rm{W}/\rm{m}^2/\rm{Hz}`,
   that will be used by this atmosphere model. Reasonable values for this are
   in the range [50, 400]. This value is the average of the flux on the day of
   interest.

   **Default:** 150

.. command:: average_solar_flux <real-value>

   Set the average of the 10.7 cm solar flux, in units of :math:`10^{-22} \rm{W}/\rm{m}^2/\rm{Hz}`,
   that will be used by this atmosphere model. Reasonable value for this are in
   the range [50, 400]. This value is the 81 day running average flux centered on
   the day of interest.

   **Default:** 150

.. command:: geomagnetic_index <real-value>

   Set the geomagnetic activity, :math:`K_p`. The provided value must be in the
   range [0, 9].

   **Default:** 0
