!
! this is a limited point version of surface program.
!
! this program runs in two different modes:
!
! 1. analysis mode (fh=0.)
!
! this program merges climatology, analysis and forecast guess to create
! new surface fields. if analysis file is given, the program
! uses it if date of the analysis matches with iy,im,id,ih (see note
! below).
!
! 2. forecast mode (fh.gt.0.)
!
! this program interpolates climatology to the date corresponding to the
! forecast hour. if surface analysis file is given, for the corresponding
! dates, the program will use it.
!
! note:
!
! if the date of the analysis does not match given iy,im,id,ih, (and fh),
! the program searches an old analysis by going back 6 hours, then 12 hours,
! then one day upto nrepmx days (parameter statement in the subrotine fixrd.
! now defined as 8). this allows the user to provide non-daily analysis to
! be used. if matching field is not found, the forecast guess will be used.
!
! use of a combined earlier surface analyses and current analysis is
! not allowed (as was done in the old version for snow analysis in which
! old snow analysis is used in combination with initial guess), except
! for sea surface temperature. for sst anolmaly interpolation, you need to
! set lanom=.true. and must provide sst analysis at initial time.
!
! if you want to do complex merging of past and present surface field analysis,
! you need to create a separate file that contains daily surface field.
!
! for a dead start, do not supply fnbgsi or set fnbgsi=' '
!
! lugb is the unit number used in this subprogram
! len ... number of points on which sfccyc operates
! lsoil .. number of soil layers (2 as of april, 1994)
! iy,im,id,ih .. year, month, day, and hour of initial state.
! fh .. forecast hour
! rla, rlo -- latitude and longitudes of the len points
! sig1t .. sigma level 1 temperature for dead start. should be on gaussian
! grid. if not dead start, no need for dimension but set to zero
! as in the example below.
