 D ata control
Some basic criteria are used (D. Swift Univ. Washington) for the data quality now:
  • A data of float that is older than 30 days rejectes for GTS publication.
  • A float that has not a valid location fix is rejected as required for GTS publication.
  • A data of float with a gap between adjacent observations that exceeds 300 dbars is rejected.
  • A data of float with not monotonic increasing of pressure is rejected.
  • A data of float with abrupt changes in values of temperature and salinity (more than 3 sigma) is rejected.
