File-Contents (in Catchwords)

steering data

• Block Program_Parameters: general steering data
  1. Max_Read_Storage: maximum number of data items read from input file during each analysis cycle. This value, multiplied with either 24 (REAL Single) or 48 (REAL Double), gives in good approximation NCDELTA's memory requirements (in Byte).
  2. Max_Distance: maximum distance in [m] up to which points with different location are compared.
  3. (optional) Print_Modus_Classify: parameter to steer informative printout messages in program section classification:
     1. 0 = no extensive messages printed;
     2. 1 = more extensive messages about classified variables will be printed.
  4. (optional) Print_Modus_Pairs: parameter to steer informative printout messages in program section primary partner variables:
     1. 0 = no extensive messages printed;
     2. 1 = more extensive messages about detected variable pairs will be printed;
     3. 2 = also informations about rejected variable pairs will be printed.
  5. (optional) Print_Modus_Define: parameter to steer informative printout messages in program section definition of computational results:
     1. 0 = no extensive messages printed;
     2. 1 = more extensive informations with respect to metadata of computational results will be printed.
  6. (optional) Print_Modus_Compute: parameter to steer informative printout messages in program section computation of results:
     1. 0 = no extensive messages printed;
     2. 1 = more extensive messages about computational result variables will be printed.
• Block Data_Files: data files
  1. Reference_File: file (NETCDF) with reference data (filetype cf-netcdf.nc);
  2. Variant_File: file (NETCDF) with variant data (filetype cf-netcdf.nc);
  3. Result_File: file (NETCDF) for result data (filetype cf-netcdf.nc).
• (optional) Block Data_Operations: data operations
  1. (optional) With_Ordinary_Differences: compute (.true.) common differences (if possible) or do not compute (.false.);
  2. (optional) With_Taylor_Diagram_Data: compute (.true.) data for Taylor diagram (if possible) or do not compute (.false.);
  3. (optional) With_Median: compute (.true.) median (>= 32 events) or do not compute (.false.);
  4. (optional) With_Percentiles_05_95: compute (.true.) percentiles Q05, Q95 (>= 32 events) or do not compute (.false.);
  5. (optional) With_Percentiles_01_99: compute (.true.) percentiles Q01, Q99 (>= 51 events) or do not compute (.false.).
• (optional) Block Exclude_Variable_From_NCDELTA: list of variables to be excluded from computation.
  1. Variant_Variable: variable from Variant-File. Key can be prescribed several times. With exception of the variables listed here results will be computed for all primary variable pairs.
• (optional) Block Include_Only_Variable_for_NCDELTA: list of variables for which results ar exclusively computed.
  1. Variant_Variable: variable from Variant-File. Key can be prescribed several times. Results will be solely computed for the variables listed here.
