Cdo overwrite a file

Options specific to ncks The following list provides a short summary of the features unique to ncks. When a name conflict occurs, a global attribute from input-file will overwrite the corresponding global attribute from output-file. Modification Operators to modify the metadata, fields or part of a field in a dataset.

Option -d controls the hyperslab specification. Append has differing effects depending on the uniqueness of the variables and attributes output by ncks: If a variable or attribute extracted from input-file does not have a name conflict with the members of output-file then it will be added to output-file without overwriting any of the existing contents of output-file.

Cdo div

Choosing overwrite destroys the existing output-file and create an entirely new one from the output of the ncks call. Fort the sake of simplicity, all input files will be denoted by ifile and accordingly, all output files will be denoted by ofile. The default behavior is to print data to screen if no netCDF output file is specified. Append has differing effects depending on the uniqueness of the variables and attributes output by ncks: If a variable or attribute extracted from input-file does not have a name conflict with the members of output-file then it will be added to output-file without overwriting any of the existing contents of output-file. In all cases variable attributes in output-file are superseded by attributes of the same name from input-file, and left alone if there is no name conflict. Comparison Operators to compare datasets. Specifying -a results in the variables being extracted, printed, and written to disk in the order in which they were saved in the input file. Thus it is recommended that the user backup output-file in case valuable data is accidentally overwritten. In this case the relevant dimensions must agree conform between the two files; new dimensions are created in output-file as required. Arithmetic Operators to arithmetically process datasets. Interpolation in time is possible between time steps and years. The dimension and variable indices refer to the location of the corresponding data element with respect to the variable as stored on disk i. Unless otherwise specified with -s , each element of the data hyperslab is printed on a separate line containing the names, indices, and, values, if any, of all of the variables dimensions.

Some of those operators can handle only 2D fields on a regular rectangular grid. This feature removes superfluous dimensions from a netCDF file. If output-file exists, the user will be queried whether to overwrite, append, or exit the ncks call completely.

Use -H to print data to screen if a netCDF output is specified the same behavior applies to -m. File operations Operators to perform operations on files like copy, replace, cat, merge and split.

Cdo setattribute

The resulting field is a mask containing 1 if the comparison is true and 0 if not. Specifying -a results in the variables being extracted, printed, and written to disk in the order in which they were saved in the input file. Option -d controls the hyperslab specification. The dimension and variable indices refer to the location of the corresponding data element with respect to the variable as stored on disk i. Append has differing effects depending on the uniqueness of the variables and attributes output by ncks: If a variable or attribute extracted from input-file does not have a name conflict with the members of output-file then it will be added to output-file without overwriting any of the existing contents of output-file. Amongst others, one can add, subtract, multiply or divide a constant. Thus -a retains the original ordering of the variables. Interpolation Operators to interpolate datasets. The direct processing of fields is also possible. This tends to make long output lists easier to search for particular variables.

Some users may wish to avoid interactive ncks queries about whether to overwrite existing data. Comparison Operators to compare datasets.

cdo invertlat

The relevant operators classes for the BAW are listed and briefly described here from the official documentation : Information Operators to print information about datasets. Convert to NetCDF: cdo -t cosmo -f nc copy ifile. Amongst others, one can add, subtract, multiply or divide a constant.
