copy_VarCoords

Copies all named dimensions and coordinate variables from one variable to another.

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"  ; This library is automatically loaded
                                                             ; from NCL V6.2.0 onward.

	procedure copy_VarCoords (
		var_from  ,    
		var_to         
	)

Arguments

Examples

Example 1 

;---read in netCDF file and read in data
  cdf_file = addfile("slp.1963.nc","r") 
  slp      = cdf_file->slp(:,::-1,:)                     ; slp has coordinate arrays

  newslp = ((slp*slp@scale_factor)+slp@add_offset)*.01   ; newslp won't have any coordinate arrays
  copy_VarCoords(slp,newslp)                             ; copy coordinate arrays from slp to newslp
