Catchwords
postprocessor
Merge contents of various netcdf.nc files
Change of time step for optional time-equidistant data records
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 merging variables from multiple netcdf.nc input files into one single netcdf.nc output file.
Input-Files
- general input data (file type ncmerge.dat);
- Input data, multiple files (file type cf-netcdf.nc).
Output-Files
- Output data (file type netcdf.nc)
- (optional) informative printer file of program execution (file type ncmerge.sdr)
- (optional) trace of program execution (file type ncmerge.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 files;
- Determine transfer operations for primary variables;
- Determine transfer operations for all other variables;
- Comparison of the input data specified by the user with the data available in the input file;
- Create common time coordinate variables for all output variables;
- (optional) Adjustment of MD5 hash values between all input data files;
- Copy the variables to be transferred from the input files to the output file.
