= PDAFomi_get_interp_coeff_lin1D =

This page documents the routine `PDAFomi_get_interp_coeff_lin1D` of PDAF-OMI.

The routine is called in `init_dim_obs_OBSTYPE of an obseration module to initialize interpolation coefficients in one dimension. It is used if the observation operator performs linear interpolation in 1D.

|| See the [wiki:OMI_observation_operators page describing PDAF-OMI observation operators] for a general overview.||

The interface is:
{{{
  SUBROUTINE PDAFomi_get_interp_coeff_lin1D(gcoords, ocoord, icoeff)

    REAL, INTENT(in)    :: gcoords(:)  ! Coordinates of grid points (dim=2)
    REAL, INTENT(in)    :: ocoord      ! Coordinate of observation
    REAL, INTENT(inout) :: icoeff(:)   ! Interpolation coefficients (dim=2)
}}}

'''Note:'''
 * This routine is a simplification of `PDAFomi_get_interp_coeff` which computes interpolation coefficients up to three dimensions
