Short Description of Functionality

Program NCAGGRGATE may be useful in the following typical situations:

• aggregation of synoptic transport data for control volumes aiming at a precise balance of transports (water volume, salt, etc.):
  1. UNTRIM2007 or UNTRIM2,
  2. NCAGGREGATE,
  3. INSPECT_CONTROL_VOLUMES (check results),
  4. NCANALYSE, and
  5. DISPLAY_CONTROL_VOLUMES.
• aggregation of synoptic data (water level, salinity, etc.) aiming at the reduction of data complexity:
  1. UNTRIM2007 or UNTRIM2,
  2. NCAGGREGATE, and
  3. NCPLOT.
• aggregation of characteristic numbers aiming at the reduction of data complexity:
  1. UNTRIM2007 or UNTRIM2,
  2. NCANALYSE,
  3. NCPLOT (check characteristic numbers),
  4. NCAGGREGATE, and
  5. NCPLOT.
• aggregation of differences for characteristic numbers or synoptic data aiming at the reduction of data complexity:
  1. UNTRIM2007 or UNTRIM2,
  2. NCANALYSE (computation of characteristic numbers),
  3. NCPLOT (check characteristic numbers),
  4. NCDELTA,
  5. NCPLOT (check differences),
  6. NCAGGREGATE, and
  7. NCPLOT.

Picture control volumes and exchanges.

Input-Files

1. general input data (file type ncaggregate.dat);
2. synoptic data sets (file type cf-netcdf.nc);
3. control volumes (file type ipds.dat).

Output-Files

1. data analysis result files (file type cf-netcdf.nc)
2. (optional) informative printer file of program execution (file type ncaggregate.sdr)
3. (optional) trace of program execution (file type ncaggregate.trc)

Methodology

Physical data, suitable for aggregation, are collected for different control volumes as well as exchanges between adjacent control volumes.
