netCDF files describe all dimensions necessary to work with. In the climate community, this format is widely used following the CF conventions. Dimensions such as longitude, latitude and time are included in NetCDF files as vectors.

Time is a key dimension from NetCDF files that could lead to flawed studies or unused data if misdeclared. nctime allows researchers to easily diagnose the time definition of their data to ensure a proper analysis. It provides two netCDF tools:

• the netCDF Time Coverage Checker :: nctcck

  Analyses the time continuity of datasets split across files.

• the netCDF Time Axis Checker :: nctxck

  Analyses the time axis correctness by rebuilding a convention-compliant time axis for netCDF files.

See the Frequently asked questions to learn more about what is behind the scene of nctime.
