Short Description of Functionality

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

Input-Files

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

Output-Files

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

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.
