Understanding the IPCC Special Report on 1.5°C
In 2015 governments adopted the Paris Agreement to tackle climate change (see below) and invited the IPCC to prepare a special report in 2018 to assess the impacts and related pathways of warming of 1.5ºC. This brief provides context and explanation of key concepts for policymakers, media and others about the Special Report on 1.5°C, scheduled to be published, subject to approval, by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. This brief is produced prior to the release of the report and therefore does not contain results from the report itself.
WIGOS Technical Report, 2018-01. WIGOS, WMO Integrated Global Observing System - Benefits to the Environment and Society from the Availability and Use of AMDAR Data
This report presents an updated summary of AMDAR data usage and the resulting impacts and benefits to meteorological forecasting and the aviation industry. It then provides a presentation of the environmental and climate applications and studies that also benefit from the use of AMDAR data, as a result, bringing benefits to the environment and wider society. These areas of societal benefits include weather, transportation, energy, disaster reduction, health, climate and agriculture.
WWRP, 2018-1. Peer Review Report on Global Precipitation Enhancement Activities
WMO, 2018In order to be most beneficial, this review focuses exclusively on the scientific basis for precipitation enhancement. Hail suppression, fog dispersion or harvesting as well as subjects related to geoengineering were, thus, out of scope for this current assessment. In addition, to provide the most useful information, the report focuses on the two cloud types most seeded in the past: winter orographic cloud systems and convective cloud systems. The review is structured in five thematic chapters
AeM Series, 01. Outcomes of the 2016-2017 Global Survey on Aeronautical Meteorological Service Provision : WMO Commission for Aeronautical Meteorology. Full report
A global survey of aeronautical meteorological service provision was conducted by the Commission for Aeronautical Meteorology (CAeM) between November 2016 and February 2017.
The primary objective of the survey was to establish a comprehensive, consolidated global view on the existing institutional arrangements for the provision of meteorological services to international air navigation, particularly at a national level, taking into account the supporting ICAO and WMO regulatory frameworks.

A Disaster Risk Reduction Roadmap for the World Meteorological Organization : final draft (version 2.1), 31 March 2017
The Roadmap is first and foremost a document that can be used by both WMO Members, partners and users to understand how NMHSs in partnership with other agencies contribute to increasing the resilience of communities, nations, regions, and the world under the above-mentioned frameworks, through a coordinated WMO-wide plan of action on DRR. It is hoped that this Roadmap will guide the Organization, in particular the NMHSs as well as key partners, in the development of its strategic and operating plans that fully take into account the contributions of the WMO community to all components and phase ...
Energy Exemplar to the User Interface Platform of the Global Framework for Climate Services
The goal of this Exemplar is to illustrate how the development and application of targeted climate products and services through the Global Framework for Climate Services (GFCS) can advance efforts to better integrate climate information into the planning and operations of the energy sector. This will enable improved sustainability, resilience and efficiency of energy systems under ever-changing weather and climate conditions.

Good practice guidelines for water data management policy : world water data initiative
Bureau of Meteorology ; World Meteorological Organization (WMO) - Australian Bureau of Meteorology, 2017These guidelines acknowledge that it is difficult to gather support for and then prosecute actions that are disruptive to the status quo and requiring considerable public investment. It is stressed that planning the water data reform journey is every bit as challenging as implementing the reforms themselves. Accordingly, these guidelines conclude with a recommended series of steps to get started in reforming water data management arrangements. Guidance is provided for (1) taking stock of current policy settings, (2) preparing the case for reform, (3) positioning for effective implementation an ...
