! <OVERVIEW>
!   Routines for determining the saturation vapor pressure
!   (<TT>ES</TT>), saturation vapor specific humidity and saturation
!   vapor mixing ratio, and their derivatives with respect to
!   temperature.
! </OVERVIEW>

! <DESCRIPTION>
!   This module contains routines for determining the saturation vapor
!   pressure (<TT>ES</TT>) from lookup tables constructed using equations given
!   in the Smithsonian tables.  The <TT>ES</TT> lookup tables are valid between
!   -160C and +100C (approx 113K to 373K).

!   The values of <TT>ES</TT> are computed over ice from -160C to -20C,
!   over water from 0C to 100C, and a blended value (over water and ice)
!   from -20C to 0C.

!   Routines are also included to calculate the saturation specific
!   humidity and saturation mixing ratio for vapor, and their deriv-
!   atives with respect to temperature.  By default, the values returned
!   are those at saturation; optionally, values of q and mr at a spec-
!   ified relative humidity may instead be returned. Two forms are
!   available; the approximate form that has been traditionally used in
!   GCMs, and an exact form provided by SJ Lin in which saturation is
!   reached while maintaining constant pressure and temperature.

!   This version was written for non-vector machines.
!   See the <LINK SRC="#NOTES">notes</LINK> section for details on vectorization.

!   </REFERENCE>

!   <BUG>
!     No error checking is done to make sure that the size of the
!     input and output fields match.
!   </BUG>

!   <NOTE>
!     1. <B>Vectorization</B><BR/>
!        To create a vector version the lookup routines need to be modified.
!    The local variables: tmp, del, ind, should be changed to arrays
!    with the same size and order as input array temp.
!
!     2. <B>Construction of the <TT>ES</TT> tables</B><BR/>
!         The tables are constructed using the saturation vapor pressure (<TT>ES</TT>)
!    equations in the Smithsonian tables. The tables are valid between
!    -160C to +100C with increments at 1/10 degree. Between -160C and -20C
!    values of <TT>ES</TT> over ice are used, between 0C and 100C values of<TT> ES</TT>
!    over water are used, between -20C and 0C blended values of <TT>ES</TT>
!    (over water and over ice) are used.
!
!    There are three tables constructed: <TT>ES</TT>, first derivative
!       (<TT>ES'</TT>), and
!    second derivative (<TT>ES</TT>'').  The ES table is constructed directly from
!    the equations in the Smithsonian tables. The <TT>ES</TT>' table is constructed
!    by bracketing temperature values at +/- 0.01 degrees. The <TT>ES</TT>'' table
!    is estimated by using centered differencing of the <TT>ES</TT>' table.
!
!     3. <B>Determination of <TT>es</TT> and <TT>es'</TT> from lookup tables</B><BR/>
!         Values of the saturation vapor pressure (<TT>es</TT>) and the
!    derivative (<TT>es'</TT>) are determined at temperature (T) from the lookup
!    tables (<TT>ES</TT>, <TT>ES'</TT>, <TT>ES''</TT>)
!    using the following formula.
!<PRE>
!    es (T) = ES(t) + ES'(t) * dt + 0.5 * ES''(t) * dt**2
!    es'(T) = ES'(t) + ES''(t) * dt
!
!    where     t = lookup table temperature closest to T
!             dt = T - t
!</PRE>
!
!     4. Internal (private) parameters<BR/>
!       These parameters can be modified to increase/decrease the size/range
!    of the lookup tables.
!<PRE>
!!    tcmin   The minimum temperature (in deg C) in the lookup tables.
!!              [integer, default: tcmin = -160]
!!
!!    tcmax   The maximum temperature (in deg C) in the lookup tables.
