On August 7, 2013, NOAA’s National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) released new data products over the Global Telecommunication System (GTS).   Included in this release is a set of one-minute water level data products, formatted into Character form for the Representation and EXchange of data (CREX) messages.  CREX is table-driven code that follows World Meteorological Organization definitions, and allows a large set of data to be succinctly formatted into a human-readable message.   One-minute water level data from each CO-OPS station is transmitted via GOES, Iridium, or phone/IP, and ingested into CO-OPS systems.  During this ingestion process, the data are organized into regionalized CREX bulletins and disseminated over the GTS.  WMO headers for these bulletins are:

SZNT31 KWBC (AtlanticCoast)

SZGX32 KWBC (GulfCoast)

SZCA33 KWBC (CaribbeanIslands)

SZPZ34 KWBC (PacificCoast)

SZAK35 KWBC (AlaskaCoast)

SZHW36 KWBC (Hawaii)

SZPA37 KWBC (Pacific Islands)

These products address a need for high-frequency sea level data collected at stations outside of the GOES footprint.  CO-OPS plans to also develop BUFR products (the binary counterpart to CREX) in the near future.

About the Tsunami Programme

UNESCO supports Member States in improving capabilities for tsunami risk assessment, implementing early warning systems and enhancing preparedness of communities at risk. UNESCO works closely with national institutions and promotes inter-institutional and regional cooperation. Specialized regional centers provide tsunami information that, together with national analysis, is the basis of the warnings issued for the public. In addition, UNESCO promotes community-based approaches in the development of response plans and awareness campaigns which strongly involve education institutions and end-users.
