e.
Coast Guard units required to take observations on the forms noted above shall observe
and record weather conditions at the meteorological synoptic hours: 0000Z, 0300Z,
0600Z, 0900Z, 1200Z, 1500Z, 1800Z, and 2100Z. Supplemental or alternate
observation times may be prescribed by special local agreement.
7.
WEATHER REPORTING PROGRAM.
a.
District commanders have designated certain Coast Guard units as weather reporting units.
These units have been assigned three letter identifiers by the FAA. Reporting units will
transmit data entries from their NOAA Form 72-5a to their collection points, using the
assigned station identifier codes.
b.
Timely reporting of data is critical and delivery of the data collected should be made at once
by the swiftest means available in a standardized format. In order to ensure this, specific
communication and format procedures are provided in enclosure (2).
c.
Enclosure (3) lists several conditions which will necessitate a special report to be made. The
heading "Special Report" will be used to denote these reports to the collection point.
"Special Reports" are to be transmitted immediately and should not be delayed.
d.
Coast Guard communications/radio stations shall accept weather messages for the National
Weather Service from any reporting unit (government or non-government). (This does not
preclude any Coast Guard unit from accepting weather information from any source.)
8.
DISPOSITION OF COMPLETED WEATHER LOGS.
a.
Non-reporting units (i.e., without real time transmission requirements) should mail completed
forms at the end of each quarter (three months) to:
National Climatic Data Center
Federal Building
Asheville, North Carolina 28801-2696
Attn: Archival Services Branch
Preaddressed envelopes may be ordered from the CG Supply Center, Brooklyn, New York
using National Stock Number 7530-00-F02-3770.
b.
Reporting units (i.e., units with real time transmission requirements) will mail completed
forms each month to their National Weather Service monitoring office (enclosure (1)).
Preaddressed envelopes will be provided by that office.
c.
Records Storage: It is not necessary to retain copies of completed forms on board any unit.
The National Climatic Data Center Archives constitute an official public records depository
and all completed weather log forms are stored there.
