====== Glory simulation ======

The glory is an optical phenomenon which can be observed from the airplane or from a mountain, when the sun is in the back of the observer (http://en.wikipedia.org/wiki/Glory_%28optical_phenomenon%29). Very high angular resolution about the backscatter region (~177°-180°, corresponding to umu~0.998-1 if the sun is in the zenith) is required to resolve the glory (see {{:teaching:radiative_transfer:mayer2007.pdf|}}). Use //rte_solver disort2// to simulate the glory at various wavelengths between 400 and 600 nm. What do you observe? 

//Hints://

  * Use the libRadtran input file and the plotting script from [[teaching:radiative_transfer:disort_nstr1|exercise 6]] to start.
  * Look at [[teaching:radiative_transfer:disort_nstr2|exercise 8]] to see how a cloud layer is defined in libRadtran.
