!**** *SUAERV* - PARAMETERS FOR THE VERTICAL DISTRIBUTIONS OF AEROSOLS.

!     PURPOSE.
!     --------

!          THIS ROUTINE COMPUTES THE VALUES *PVDAEN* (*N=*S,*L,*U OR *D
!     FOR SEA,LAND,URBAN OR DESERT) OF A SURFACE-NORMALISED VERTICAL
!     DISTRIBUTION OF AEROSOLS' OPTICAL DEPHTS FROM THE ARGUMENT *PETAH*
!     (VERTICAL COORDINATE) AT *KLEVP1* LEVELS. IT ALSO SETS VALUES FOR
!     NON-GEOGRAPHICALLY WEIGHTED TOTAL OPTICAL DEPTHS (AT 0.55 E-06
!     WAVE-LENGTH) *PAEOPN* FOR THE SAME FOUR TYPES AND SIMILEAR OPTICAL
!     DEPHTS DIVIDED BY PRESSURE FOR BACKGROUND WELL-MIXED AEROSOLS
!     OF THREE TYPES *PMNBGA* (*MN*=*TR*,*VO* OR *ST* FOR TROPOSPHERIC,
!     VOLCANIC (STRATOSPHERIC ASHES) OR STRATOSPHERIC (SULFURIC TYPE)).
!     IT FINALLY SET VALUES FOR THE POWER TO BE APPLIED TO A TEMPERATURE
!     RATIO SMALLER THAN ONE IN ORDER TO OBTAIN AN IDEX ONE IN THE
!     STRATOSPHERE AND ZERO IN THE TROPOSPHERE WITH A RELATIVELY SMOOTH
!     TRANSITION (*PTRPT*), AS WELL AS FOR ADSORPTION COEFFICIENTS FOR
!     WATER TO THE THREE TYPE OF TROPOSPHERIC AEROSOLS (*PAEADK*) WITH
!     A MINIMUM VALUE (IN THE WHOLE ATMOSPHERE) FOR THE SUM OF THE
!     PRODUCTS OF *PAEADK* BY THE OPTICAL DEPTHS DIVIDED BY PRESURE
!     THICKNESS: *PAEADM*.

!**   INTERFACE.
!     ----------

!          *SUAERV* IS CALLED FROM *SUECRAD*.
!          THERE ARE SIXTEEN DUMMY ARGUMENTS: *PETAH* IS THE VERTICAL
!     COORDINATE.
!                                             *PVDAEN* (*N=*S,*L,*U OR
!     *D) ARE THE NORMALISED VERTICAL DISTRIBUTIONS.
!                                             *KLEVP1* IS THE NUMBER OF
!     LEVELS.
!                                             *PMNBGA* (*MN*=*TR*,*VO*
!     OR *ST*) ARE THE BACKGROUND OPTICAL DEPTHS DIVIDED BY PRESSURE.
!                                             *PAEOPN* (*N=*S,*L,*U OR
!     *D) ARE THE TOTAL OPTICAL DEPHTS FOR THE VERTICALLY VARYING
!     AEROSOLS.
!                                             *PTRPT* IS THE TEMPERATURE
!     EXPONENT FOR THE STRATOSPHERIC DEFINITION.
!                                             *PAEADK* (1,2,3) AND
!     AND *PAEADM* ARE THE CONSTANTS FOR THE DEFINITION OF THE QUANTITY
!     OF WATER VAPOUR THAT WILL BE ADSORBED TO THE DRY AEROSOLS TO FORM
!     MOIST AEROSOLS.

!     METHOD.
!     -------

!          STRAIGHTFORWARD, EQUIVALENT HEIGTHS ARE GIVEN IN METERS (8434
!     FOR THE ATMOSPHERE) AND TROPOSPHERIC AND STRATOSPHERIC PRESSURE
!     BOUNDARY VALUES ARE SET AT 101325 AND 19330 *PASCAL.

!     EXTERNALS.
!     ----------

!          NONE.

!     REFERENCE.
