of planned or completed CLIVAR hydrographic cruises provided by the CLIVAR-IPO. Also available is
the status of CLIVAR underway meteorological data provided to
the DAC. All CLIVAR chief scientists are encouraged to submit
their meteorological data.
Additional ship-board meteorological data are
available for past field experiments.
The CLIVAR Data Assembly Center obtains the underway
meteorological from CLIVAR cruises directly from principal
investigators, national data centers, and vessel operators. The
underway data are converted to a common netCDF format and are then
quality controlled using automated and visual inspections.
Automated routines identify unrealistic values, statistical
outliers, incorrect ship positions and movement, and values that
are out of proper time sequence. A visual evaluation of all
variables is completed by trained meteorologists to identify
significant problems or identify interesting meteorological events.
Each problematic data value is assigned an appropricate quality
of goals and progress for CLIVAR.
