boundaries Module

  1. boundaries.f90
  2. boundaries

For reading and storing boundary conditions.

This module handles the reading and storing of the land-sea mask, the surface geopotential (i.e. the orography), the filtered surface geopotential (i.e. the smoothed orography) and the bare-land annual-mean albedo.

Arguments

None

public subroutine forchk(fmask, nf, fmin, fmax, fset, field)

Check consistency of surface fields with land-sea mask and set undefined values to a constant (to avoid over/underflow).

Arguments

Type IntentOptional AttributesName

real, intent(in) :: fmax

The maximum allowable value
real, intent(in) :: fset

Replacement for undefined values
real, intent(inout) :: field(ix,il,nf)

The output field

private subroutine spectral_truncation(fg1, fg2)

Compute a spectrally-filtered grid-point field.

Arguments
