Notice of document conversion
The WMO Secretariat is in the process of migrating from MS Office 2003 to MS Office 2010. As part of this transition, the standard extension for Word documents will change from .doc to .docx. The content of the documents will remain unchanged, although there may occasionally be small differences in the layout.
Documents in MS Office 2010 format (extension .docx) can be viewed and edited in previous versions of MS Office. If you experience compatibility issues, you can view the document by clicking on the document name. From there you can download a PDF version of the document by clicking on the printer icon and selecting Print (PDF).
Although the documents in the new format will show a different release date, a list with the original dates of publication will be made available for reference purposes.
We thank you for your understanding.
