hgrid_ak_dd()

subroutine pesg::hgrid_ak_dd::hgrid_ak_dd ( integer(spi), intent(in)  lx, integer(spi), intent(in)  ly, integer(spi), intent(in)  nx, integer(spi), intent(in)  ny, real(dp), intent(in)  a, real(dp), intent(in)  k, real(dp), intent(in)  pdlat, real(dp), intent(in)  pdlon, real(dp), intent(in)  pdazi, real(dp), intent(in)  delx, real(dp), intent(in)  dely, real(dp), dimension(lx:lx+nx ,ly:ly+ny ), intent(out)  gdlat, real(dp), dimension(lx:lx+nx ,ly:ly+ny ), intent(out)  gdlon, real(dp), dimension(lx:lx+nx-1,ly:ly+ny-1), intent(out)  garea, logical, intent(out)  ff  )

Use a and k as the parameters of an Extended Schmidt-transformed Gnomonic (ESG) mapping centered at (pdlat,pdlon) and twisted about this center by an azimuth angle of pdazi counterclockwise (these angles in degrees).

Like hgrid_ak_rr, return the grid points' lats and lons, except that here the angles are returned in degrees. Garea, the area of each grid cell, is returned as in hgrid_ak_rr, and a failure flag, ff, raised when a failure occurs anywhere in these calculations.

Parameters

[in]	lx	center-relative x grid index for left edge of the domain
[in]	ly	center-relative y grid index for lower edge of the domain
[in]	nx	number of the grid spaces in x
[in]	ny	number of the grid spaces in y
[in]	a	parameter of an ESG mapping
[in]	k	parameter of an ESG mapping
[in]	pdlat	degrees latitude of the projection center of mapping
[in]	pdlon	degrees longitude of the projection center of mapping
[in]	pdazi	degrees azimuth of orientation of mapping at its center
[in]	delx	central x-spacing of the grid (in radians)
[in]	dely	central y-spacing of the grid (in radians)
[out]	gdlat	array of grid point latitudes (in degrees)
[out]	gdlon	array of grid point longitudes (in dgrees)
[out]	garea	array of grid cell areas (in steradians)
[out]	ff	failure flag
