postprocessor
Selective deletion or copying of variables in a netcdf.nc file
Delete/Copy coordinate variables of a certain type (X-Y or LON-LAT)
Delete/Copy variables belonging to a grid (Mesh)
Delete/Copy of individual variables
Deletion/Copying of individuual dates of synoptic, time-equidistant data records
Automatic setting of the WRITE chunk size
Storage of the content of the ASCII input control files in netcdf.nc (as a variable)
Storage of the MD5 hash values of input files in netcdf.nc (as a variable)
optional use of Message Passing Interface (MPI, MPI Forum)
Acknowledgment: This project took advantage of netCDF software developed by UCAR/Unidata (www.unidata.ucar.edu/software/netcdf/).
Short Description of Functionality
The program enables the selective deletion / copying of variables in a netcdf.nc input file into an equivalent output file.
Input-Files
- general input data (file type ncdvar.dat);
- Input data, data record to be thinned (file type cf-netcdf.nc).
Output-Files
- Output data (file type netcdf.nc)
- (optional) informative printer file of program execution (file type ncdvar.sdr)
- (optional) trace of program execution (file type ncdvar.trc)
Methodology
The program is subdivided into the following sections:
- Read, check and print the control data of the user;
- Read metadata of the input data;
- Transfer metadata into internal data objects;
- Classification of all variables of the input file;
- Comparison of the input data specified by the user with the data available in the input file;
- Mark all primary variables that can be selected by the user with COPY or DELETE;
- Deriving the transfer method (COPY, DELETE) for the variables used by the primary variables (coordinate variable, auxiliary variable, etc.);
- Copy the variables to be transferred from the input to the output file.
