calculate_grid_properties()

subroutine mo_grid::calculate_grid_properties ( integer(i4), intent(in)  nrowsin, integer(i4), intent(in)  ncolsin, real(dp), intent(in)  xllcornerin, real(dp), intent(in)  yllcornerin, real(dp), intent(in)  cellsizein, real(dp), intent(in)  aimingresolution, integer(i4), intent(out)  nrowsout, integer(i4), intent(out)  ncolsout, real(dp), intent(out)  xllcornerout, real(dp), intent(out)  yllcornerout, real(dp), intent(out)  cellsizeout  )

Calculates basic grid properties at a required coarser level using information of a given finer level.

Calculates basic grid properties at a required coarser level (e.g., L11) using information of a given finer level (e.g., L0). Basic grid properties such as nrows, ncols, xllcorner, yllcorner cellsize are estimated in this routine.

TODO: add description

[in]	real(dp) :: xllcornerIn	xllcorner at an input level
[in]	real(dp) :: yllcornerIn	yllcorner at an input level
[in]	real(dp) :: cellsizeIn	cell size at an input level
[in]	real(dp) :: aimingResolution	resolution of an output level
[out]	integer(i4) :: nrowsOut	no. of rows at an output level
[out]	integer(i4) :: ncolsOut	no. of cols at an output level
[out]	real(dp) :: xllcornerOut	xllcorner at an output level
[out]	real(dp) :: yllcornerOut	yllcorner at an output level
[out]	real(dp) :: cellsizeOut	cell size at an output level

Here is the caller graph for this function:

init_lowres_level()

subroutine, public mo_grid::init_lowres_level	(	type(grid), intent(in), target	highres,
		real(dp), intent(in)	target_resolution,
		type(grid), intent(inout), target	lowres,
		type(gridremapper), intent(inout), optional	highres_lowres_remap
	)

Level-1 variable initialization.

following tasks are performed for L1 datasets

• cell id & numbering
• mask creation
• storage of cell cordinates (row and coloum id)
• sorage of four corner L0 cordinates If a variable is added or removed here, then it also has to be added or removed in the subroutine config_variables_set in module mo_restart and in the subroutine set_config in module mo_set_netcdf_restart

  Parameters

  [in]	type(Grid) :: highres
  [in]	real(dp) :: target_resolution
  [in,out]	type(Grid) :: lowres
  [in,out]	type(GridRemapper), optional :: highres_lowres_remap

level 0 variable initialization

following tasks are performed for L0 data sets

• cell id & numbering
• storage of cell cordinates (row and coloum id)
• empirical dist. of terrain slope
• flag to determine the presence of a particular soil id in this configuration of the model run If a variable is added or removed here, then it also has to be added or removed in the subroutine config_variables_set in module mo_restart and in the subroutine set_config in module mo_set_netcdf_restart

  Parameters
