Packing reduces the data volume by reducing the precision of the stored numbers. It is implemented using the NetCDF attributes add_offset and scale_factor. The operator unpack unpack all packed variables. The default data type for all variables is automatically changed to 32-bit floats. Use the CDO option -b F64 to change the data type to 64-bit floats, if needed.

Usage

cdo_unpack(ifile, ofile = NULL)

Arguments

ifile

String with the path to the input file.

ofile

String with the path to the output file.

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.
