VOSClim Status 
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). 
Metadata 
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).

 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).
