From: Peter Stone
Chief, Oceanographic Division
National Ocean Service (NOS) Center for Operational
Oceanographic Products and Services (CO-OPS)
Subject: NOS/CO-OPS is implementing new Character form for the
Representation and EXchange of Data (CREX) Products,
Effective August 7, 2013.
Effective August 7, 2013 at 1500 Coordinated Universal Time
(UTC), CO-OPS will release CREX messages containing 1-minute
water level data (total water levels) from approximately 200
water level stations around the U.S. Coast, including ocean
islands. These products are transmitted every 3 minutes on the
Global Telecommunications System (GTS) and will not be ingested
by AWIPS. The World Meteorological Organization (WMO) headers for
these 1-minute water level data products are:
SZNT31 KWBC (Atlantic Coast)
SZGX32 KWBC (Gulf Coast)
SZCA33 KWBC (Caribbean Islands)
SZPZ34 KWBC (Pacific Coast)
SZAK35 KWBC (Alaska Coast)
SZHW36 KWBC (Hawaii)
SZPA37 KWBC (Pacific Islands)
Effective August 7, 2013, 1500 UTC, CO-OPS will release CREX
products containing 6-minute water level data and residuals
(total water level minus astronomical tide) from approximately
300 water level stations, which includes the Great Lakes. These
messages will be released every 6 minutes on the GTS and will not
be ingested by AWIPS. Every 30 minutes, CO-OPS will also release
a supplemental meteorological message containing wind speed and
direction, air temperature and barometric pressure collected at
the water level stations. WMO headers for these 6-minute water
level and 30-minute meteorological data products are:
KSAA30 KWBC, Atlantic Coast (0-90 W Northern Hemisphere)
KSAA31 KWBC, Gulf Coast (0-90 W Northern Hemisphere)
KSAA32 KWBC, Great Lakes (0-90 W Northern Hemisphere)
KSAB30 KWBC, Great Lakes (90 W - 180 Northern Hemisphere)
KSAB31 KWBC, Gulf Coast (90 W - 180 Northern Hemisphere)
KSAB32 KWBC, Pacific Coast
KSAB33 KWBC, Alaska
KSAE30 KWBC, Caribbean Islands
KSAF30 KWBC, Hawaii
KSAG30 KWBC, Pacific Islands (180 - 90 E Tropical)
KSAJ30 KWBC, Pacific Islands (90 - 180 Southern Hemisphere)
All messages will use Edition 1 formats.
The 1-minute water level messages use sequence identifier B22038
(water level elevation) replicated 6 times.
The 6-minute messages use D06025, which includes B22038 and
B22039 (residual). Meteorological messages use D06021.
All bulletins contain latitude/longitude information using
D01021. All stations are identified by the same identifier that
CO-OPS uses in its Standard Hydrometeorological Exchange Format
(SHEF) messages.
The identifier is a NWS Location Identifier (NWSLI), but is
referred to as a SHEF ID in NOS applications. You can map the
SHEF ID to the 7-digit NOS identifier Web Services Active
Stations XML query:

ops.nos.noaa.gov/axis/webservices/activestations/response.jsp?v=2
&format=xml&Submit=Submit
Effective September 30, 2013 at 1500 UTC, CO-OPS will discontinue
the existing hourly CREX bulletins distributed under the WMO
headers SOUS5i, SOAK5i, and SOPA5i KWBC.
