## Short Description of Functionality

Program NCANALYSE serves as an analysis program for data stored in CF netCDF data files.

### Input-Files

**general input data**(file type ncanalyse.dat);**synoptic data sets**(file type CF-NETCDF.NC);- for automatic quality assurance (file type bounds_verify.dat).

### Output-Files

**data analysis result files**(file type CF-NETCDF.NC)- (optional) informative
**printer file**of program execution (file type ncanalyse.sdr) - (optional)
**trace**of program execution (file type ncanalyse.trc)

### Methodology

The following data analysis methods are currently available:

- Tidal Characteristic Numbers:
- Tidal Characteristic Numbers of Water Level;
- Tidal Characteristic Numbers of Current;
- Tidal Characteristic Numbers of Salinity;
- Tidal Characteristic Numbers of Temperature;
- Tidal Characteristic Numbers of Suspended Sediment;
- Tidal Characteristic Numbers of Tracer Load;
- Tidal Characteristic Numbers of Effective Bed Shear Stress;
- Tidal Characteristic Numbers of Bed Load Transport.

- Tide-dependent Characteristic Numbers for Transport-Processes (based on
*exact*integrals): - Harmonic Analysis:
- Tide-Independent Characteristic Numbers:
- Characteristic Numbers of Water Level (independent of tides);
- Characteristic Numbers of Current Velocity (independent of tides);
- Characteristic Numbers of Salinity (independent of tides);
- Characteristic Numbers of Temperature (independent of tides);
- Characteristic Numbers of Suspended Sediment Concentration (independent of tides);
- Characteristic Numbers of Tracer Load (independent of tides);
- Characteristic Numbers of Oxygen Concentration (independent of tides);
- Characteristic Numbers of Morphodynamics (independent of tides);
- Characteristic Numbers of Bed Load Transport (independent of tides);
- Characteristic Numbers of Eff. Bed Shear Stress (independent of tides).

- Tide-Independent Characteristic Numbers for Transport-Processes (based on
*exact*integrals):- Characteristic Numbers of Water Transport (independent of tides);
- Characteristic Numbers of Water Transport (independent of tides);
- Characteristic Numbers of Salt Transport (independent of tides);
- Characteristic Numbers of Heat Transport (independent of tides);
- Characteristic Numbers of Tracer Transport (independent of tides);
- Characteristic Numbers of Suspended Sediment Transport (independent of tides);
- Characteristic Numbers of Sediment Transport (independent of tides) (bed an suspended load at the bottom).

- Tidal Energy Transport:
- Characteristic Numbers of Meteorological Data:
- Characteristic Numbers for Wave and Sea State:

Just in case **HDF error** is detected during read of a data record, the program tries to reconstruct the wanted data set from adjacent (in time) records for the same variable. This type of repair works for time dependent variables only.
