!!****  *AEROZON * - initialisation for ECMWF radiation scheme in the MesoNH framework
!!
!!    PURPOSE
!!    -------
!!      Basically the same purpose as ini_radiations but only for aerosols and
!!      ozon distribution. 
!!
!!**  METHOD
!!    ------
!!      The formulae of astronomy are taken from Paltridge and Platt (1976).
!!    The latitudinal and seasonal dependences for the choice of the standard
!!    atmosphere is straightforward.
!!     The set up of ECMWF radiation package is mainly done in the "ini_radconf" routine
!!    in function of defined options ( eg use of RRTM for LW).   
!!     Ozone field and Aerosols optical thickness are defined through specific 
!!    climatologies. For aerosols distribution set up, several option are allowed : 
!!      1) in function of underlying cover types ( land, sea, desert, town) 
!!      2) using the ECMWF global distribution of Tanre (1984) interpolated on the domain  
!!   The carbon dioxide concentration is homogeneously distributed at 360 ppm. Note that 
!!   other active gaz are directly initialised in ECMWF Package
!!   Finally, the radiative tendency and the short and long waves surface
!!    fluxes are read or set to 0 and also the instants at which full or 
!!    partial radiations' call has been performed. 
!!
!!    EXTERNAL
!!    --------
!!      
!!      Subroutine INI_STAND_ATM : Initialization of 5 standard atmosphere     
!!      Subroutine AEROZON   : Initialization of ECMWF radiation package constant
!!   CAUTION: the following routine do not use the MNH norm

!!      Subroutine  SUAERV          : aerosol climatology : vertical distribution
!!      Subroutine  RADAER          : interpolation on domain 
!!     these routine use ECMWF specific module "yo===="
