aeroptproperties.F @ 3026

Mars PCM:
Add a new routine to write output called write_output.
It needs to be imported (for example : use write_output_mod, only: write_output)
Then, it requires only 4 arguments : the name of the variable, its title, its units and the variable itself.
It detects the dimension of the variable and decide to output either in diagfi or diagsoil.
It is also compatible with XIOS (xml file needs to be adapted)
Writediagfi and writediagsoil routines are still available in case.

15	c Description:
16	c Compute the scattering parameters in each grid
17	c box, depending on aerosol grain sizes. Log-normal size
18	c distribution and Gauss-Legendre integration are used.
19
20	c Parameters:
21	c Don't forget to set the value of varyingnueff below; If
22	c the effective variance of the distribution for the given
23	c aerosol is considered homogeneous in the atmosphere, please
24	c set varyingnueff(iaer) to .false. Resulting computational
25	c time will be much better.
