filevarcompressleveldef

Defines a list of variable names, variable var_types, and variable dimension names for a supported file.

Prototype

	procedure filevarcompressleveldef (
		thefile       [1] : file,     
		var_name      [1] : string,   
		compressLevel [1] : integer   
	)

Arguments

The reference to the file that you want to define the variables in. This reference must be created by the addfile function.

Variable name on the file to be compressed.

An integer (1 - 9) to define the compress level.

Description

This procedure defines the compress level for a variable.

Examples

Example

Write one 2D array and two 3D arrays (with dimension names "lev", "lat", and "lon") to a netCDF file called "myfile.nc":

  setfileoption("nc", "Format",  "NetCDF4Classic")
  f = addfile("myfile.nc","c")
  filedimdef(f,(/"lev","lat","lon"/),(/10,73,144/),(/False,False,False/))
  var_names2D = (/ "PS" /)
  var_names3D = (/ "T", "Q" /)
  varvar_types2D = (/ "float" /)
  varvar_types3D = (/ "float", "float" /)
  filevardef( f, var_names2D, varvar_types2D, (/  "lat", "lon" /) )
  filevardef( f, var_names3D, varvar_types3D, (/  "lev", "lat", "lon" /) )

 ;Define the chunking size
  chunkSizes = (/5,37,72/)
  filevarchunkdef(f, "T", chunkSizes)

 ;Define the compress level
  filevarcompressleveldef(f, "T", 3)
