VOSCLIM STATUS UPDATE APRIL 2004: REPORT TO THE AOPC

The objective of the Voluntary Observing Ship (VOS) subset envisaged by the WMO
VOS Climate project (VOSClim) is to provide a source of high quality marine meteorological
data and associated metadata, suitable for a number of applications, including global climate
monitoring, research and prediction. The VOSClim project held its fourth meeting at the IMO
headquarters in London in July 2003 (VOSClim IV, JCOMM 2003a). Important progress was
reported including the full implementation of ship monitoring for all variables (by the Met
Office acting as VOSClim Real Time Monitoring Center), the agreement of Marine
Climatological Summaries Scheme (MCSS) quality assurance limits for variables in the
VOSClim attachment (by Deutscher Wetterdienst for the Global Collecting Centres) and the
results of a preliminary scientific analysis (by the Scientific Advisors). A decision was made
to relax the recruitment criteria for VOSClim ships so that any ship with a good reporting
record could participate regardless of instrumentation used. The operational side of VOSClim
is beginning to work well with many Port Meteorological Officers (PMOs) recruiting ships,
training the officers on the importance of VOSClim and how to make the additional
observations, collecting metadata, photographing the ship and instrument sites and making
repeat visits where possible. VOSClim real time data1 is available from the project website2
but delayed mode observations containing the VOSClim attachment of extra variables
designed to aid scientific analysis are not yet available3. The first journal paper analysing the
dataset will shortly be submitted (Berry and Kent 2004).
The success of VOSClim relies heavily on the availability of good quality metadata.
VOSClim has adopted the normal VOS route for metadata delivery, through the WMO
Marine Program Publication No. 47 (List of Selected, Supplementary and Auxiliary Ships).
Presently (June 2004) from 111 ships.
As of June 2004, delayed mode data is still not available from NCDC although they say that they
will do it soon (following pressure from the VOSClim Project Manager).
