Here is the caller graph for this function:

yac_check_coord_units()

int yac_check_coord_units	(	int	ncid,
		int	varid )

Checks the variable for an attribute with the name "units". If it is available and contains the string "degree", this routine will return 1, 0 otherwise.

Here is the caller graph for this function:

yac_read_coords()

void yac_read_coords	(	int	ncid,
		char const *	lon_name,
		char const *	lat_name,
		double **	lon,
		double **	lat,
		size_t *	len )

reads a coordinate array from a netcdf file, tries to interpret the units attribute of the variable and will convert the coordinates into radiant if necessary

Parameters

[in]	ncid
[in]	lon_name	name of longitude array in grid file
[in]	lat_name	name of latitude array in grid file
[out]	lon	lon array in radiant
[out]	lat	lat array in radiant
[out]	len	number of coordinates in lon and lat arrays
