Amendment Processes to WIS Manuals and Guides

The rules and procedures for amending the WIS manuals and WIS Guides are described in the Manual on Codes under the General Provisions chapter:  numbers 13 - 17 and in the General Provisions Appendix. This page summarises the options using new organisational terminology introduced by the WMO reform of 2019. The WMO experts on the SC-IMT teams are responsible for proposing, documenting, and testing the amendments.

How to Propose an Amendment

  1. Contact your National Focal Point (NFP) 
    1. NFPs for Codes and Data Representation Matters
    2. NFPs on WIS matters
  2. The NFP submits your request in an email to WMO (wis@wmo.int) or the appropriate task team lead.
  3. The task team will then review the request and introduce the change(s) with the appropriate amendment process.
