CLIVAR DAC Research Methods
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
flag.
