copy_VarAtts

Copies all of a variable's attributes 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.
                                                             ; No need for user to explicitly load.

	procedure copy_VarAtts (
		var_from  ,    
		var_to         
	)

Arguments

An array of any dimensionality. Must have attributes.

An array of any dimensionality. Must be the same size as var_from.

Description

This procedure copies all of a variable's attributes from var_from to var_to. If var_to already contains an attribute of the same name as one of var_from's attributes, then it is deleted and the new one copied over.

Examples

Example 1

;---Open file and read in variable
  in1  = addfile("b003_TS_200-299.nc","r")
  in2  = addfile("b006_TS_035-134.nc","r")
  
  tmp1 = in1->TS
  tmp2 = in2->TS

;---Reorder to get time as right most dimension
  ts1 = tmp1(lat|:,lon|:,time|:)
  ts2 = tmp2(lat|:,lon|:,time|:)

;---Calculate cross correlations
  maxlag = 2                                    ; set lag
; note, the max lag should not be more than N/4
  
  ccr = esccr(ts1,ts2,maxlag)                   ; calc cross correlations

;---Copy meta data and coordinate variables using contributed functions
  copy_VarAtts(ts1, ccr)                    
  copy_VarCoords_1(ts2,ccr)
