Guide to the WMO Integrated Processing and Prediction System WMO-No.305

The 2023 edition of the Guide to the WMO Integrated Processing and Prediction System (WMO-No. 305) was developed following the request of the WMO Executive Council at its sixty-ninth session, in order to ensure the necessary alignment with and provide further guidance to Members on implementation of the Manual on the WMO Integrated Processing and Prediction System (WMO-No. 485). In conjunction with that Manual, the Guide is designed to ensure adequate uniformity and standardization of data, information and production practices, procedures and specifications employed by WMO Members in the implementation of the WMO Integrated Processing and Prediction System (WIPPS) in support of the mission of the Organization.
