INTERFACE:

 subroutine clm_driver1 (doalb, nextsw_cday, declinp1, declin)

DESCRIPTION:

First phase of the clm driver calling the clm physics. An outline of the calling tree is given in the description of this module.

USES:

ARGUMENTS:

   implicit none
   logical , intent(in) :: doalb       ! true if time for surface albedo calc
   real(r8), intent(in) :: nextsw_cday ! calendar day for nstep+1
   real(r8), intent(in) :: declinp1    ! declination angle for next time step
   real(r8), intent(in) :: declin      ! declination angle for current time step
