INTEGER, PARAMETER :: JPIB = SELECTED_INT_KIND(12)

!Special integer type to be used for sensative adress calculations
!should be *8 for a machine with 8byte adressing for optimum performance

!     Real Kinds
!     ----------
!
INTEGER, PARAMETER :: JPRT = SELECTED_REAL_KIND(2,1)
INTEGER, PARAMETER :: JPRS = SELECTED_REAL_KIND(4,2)
INTEGER, PARAMETER :: JPRM = SELECTED_REAL_KIND(6,37)
! This parameter should always be double precision as a few parts of
! the radiation code require it
INTEGER, PARAMETER :: JPRD = SELECTED_REAL_KIND(13,300)

! This parameter governs the precision of most of the code
#ifdef PARKIND1_SINGLE
INTEGER, PARAMETER :: JPRB = JPRM
#else
INTEGER, PARAMETER :: JPRB = JPRD
#endif

! Logical Kinds for RTTOV....
