MODULE MODD_RAIN_ICE_DESCR
! ##########################
!
!!**** *MODD_RAIN_ICE_DESCR* - declaration of the microphysical descriptive
!! constants for use in the warm and cold schemes.
!!
!! PURPOSE
!! -------
! The purpose of this declarative module is to declare the microphysical
! constants. This includes the descriptive parameters for the raindrop and
! the ice crystal habits and the parameters relevant of the dimensional
! distributions.
!
! m(D) = XAx * D**XBx : Mass-MaxDim relationship
! v(D) = XCx * D**XDx : Fallspeed-MaxDim relationship
! N(Lbda) = XCCx * Lbda**XCXx : NumberConc-Slopeparam relationship
! XF0x, XF1x, XF2x : Ventilation factors
! XC1x : Shape parameter for deposition
!
! and
!
! XALPHAx, XNUx : Generalized GAMMA law
! Lbda = XLBx * (r_x*rho_dref)**XLBEXx : Slope parameter of the
! distribution law
!
