21	! Aerosol Optical Properties
22	!
23	! Description:
24	! Compute the scattering parameters in each grid
25	! box, depending on aerosol grain sizes. Log-normal size
26	! distribution and Gauss-Legendre integration are used.
27
28	! Parameters:
29	! Don't forget to set the value of varyingnueff below; If
30	! the effective variance of the distribution for the given
31	! aerosol is considered homogeneous in the atmosphere, please
32	! set varyingnueff(iaer) to .false. Resulting computational
33	! time will be much better.
34
35	! Authors: J.-B. Madeleine, F. Forget, F. Montmessin
36	! Slightly modified and converted to F90 by R. Wordsworth (2009)
37	! Varying nueff section removed by R. Wordsworth for simplicity
