> **Noting:**

(1) Manual on Marine Meteorological Service (WMO-No. 558) Volume 1,
    > Appendix 1.13,

(2) Manual on Marine Meteorological Services (WMO-No. 558) Volume 1,
    > Appendix 1.15,

(3) Final Report, First Session of the JCOMM Expert Team on Marine
    > Climatology, JCOMM Meeting Report No. 32,

> **Recognizing** that the current Minimum Quality Control Standards
> (MQCS-IV) do not extend to the additional elements introduced for the
> VOSClim Project at JCOMM-I,
>
> **Considering:**

(1) That the IMMT format remains the primary format for the exchange of
    > marine climatological data, for both the MCSS and the VOSClim
    > Project,

(2) The importance of the Minimum Quality Control Standards to the
    > quality of the data contained in the MCSS data archives,

(3) The importance to the Global Collecting Centres of maintaining both
    > the IMMT and the MQCS up to date,

> **Recommends:**

(1) That the amendments to the Manual on Marine Meteorological Services
    > and the Guide to Marine Meteorological Services as detailed in
    > Annexes 1 and 2 to this recommendation be approved, and included
    > in the appropriate appendices in the Manual and Guide;

(2) That the new version (IMMT-3) of the IMMT format be implemented
    > generally for all data collected as from 1 January 2007;

(3) That the new version of the Minimum Quality Control Standards
    > (MQCS-V) be also implemented generally for all data collected from
    > 1 January 2007;

> **Requests** the Expert Team on Marine Climatology to continue to
> review the implementation and value of the revised format and quality
> control standards, to provide technical assistance to the
> Members/Member States concerned as required and to propose further
> amendments to the format and standards as necessary;
>
> **Requests** the Secretary-General of WMO to provide appropriate
> technical advisory assistance to Members/Member States concerned, as
> required, in the implementation of the revised format and standards.
