Detailed Description

Model Initialization includes allocating memory for boundary and domain data structures. It reads all of the options from the namelist file (or files). It also reads in Lat/Lon and Terrain data. This module also sets up geographic (and vertical) look uptables for the forcing data Finally, there is a driver routine to initialize all model physics packages

The module has been updated to allow arbitrary named variables this allows the use of e.g. ERAi, but still is not as flexible as it could be

The use of various python wrapper scripts in helpers/ makes it easy to add new datasets, and make them conform to the expectations of the current system. For now there are no plans to near term plans to substantially modify this.

Here is the caller graph for this function:

subroutine init::convert_longitudes ( real, dimension(:,:), intent(inout) long_data )

private

Conver longitudes into a common format for geographic interpolation

First convert longitudes that may be -180-180 into 0-360 range first. If data straddle the 0 degree longitude, convert back to -180-180 so interpolation will be smooth

Parameters

[in,out]

long_data

2D array of longitudes (either -180 - 180 or 0 - 360)

subroutine init::interpolate_in_x	(	real, dimension(:,:), intent(in)	data_in,
		real, dimension(:,:), intent(out), allocatable	data_out
	)

private

Interpolate a 2D data array in the "x" (first) dimension, extrapolate out one on edges

If data_out is not allocated, it will be allocated as (nx+1,ny). Then a simple average between grid cells computes a bilinear interpolation. Edge cells are extrapolated outwards using a similar method.

Parameters

[in]	data_in	real 2D array to be interpolated
[out]	data_out	real 2D allocatable array to store the interpolated output

Here is the caller graph for this function:

subroutine init::interpolate_in_y	(	real, dimension(:,:), intent(in)	data_in,
		real, dimension(:,:), intent(out), allocatable	data_out
	)

private

Interpolate a 2D data array in the "y" (second) dimension, extrapolate out one on edges

If data_out is not allocated, it will be allocated as (nx,ny+1). Then a simple average between grid cells computes a bilinear interpolation. Edge cells are extrapolated outwards using a similar method.

Parameters

[in]	data_in	real 2D array to be interpolated
[out]	data_out	real 2D allocatable array to store the interpolated output
