Guide to the Management and Operation of WMO Regional Training Centres and Other Training Institutions
This publication responds to the recommendations made in the review of the future roles and operation of RTCs, which was carried out by the Executive Council Panel of Experts on Education and Training from 2012 to 2014. The review and recommendations were approved by the WMO Executive Council at its sixty-sixth session in 2014. The review underlined the importance and usefulness of the RTCs to WMO Members. However, it also noted that, for Members to get even more value from such centres, the criteria for designation and reconfirmation of RTCs needed to be improved and that Directors of RTCs wo ...
Guidelines for the Assessment of Uncertainty for Hydrometric Measurement
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...

International Cloud Atlas: Manual on the Observation of Clouds and Other Meteors
This Atlas describes the classification system for clouds and meteorological phenomena used by all WMO Members. The classifications also describe meteorological meteors other than clouds – hydrometeors, lithometeors, photometeors, and electrometeors.
The Atlas provides a common language to communicate cloud observations, and ensures consistency in reporting by observers around the world. It serves as a training tool for meteorologists, as well as for those working in aeronautical and maritime environments, and it has become popular with weather enthusiasts and cloud spotters.

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.12: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2015
The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that globally averaged surface mole fractions(3) calculated from this in situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2015, with CO2 at 400.0±0.1 ppm, CH4 at 1845±2 ppb(4) and N2O at 328.0±0.1 ppb. These values constitute, respectively, 144%, 256% and 121% of pre-industrial (before 1750) levels. It is predicted that 2016 will be the first year in which CO2 at the Mauna Loa Observatory remains above 400 ppm all year, and hence for many generations [ ...
GAW Report, 227. WMO/GAW Aerosol Measurement Procedures, Guidelines and Recommendations
It is the goal of the Global Atmosphere Watch (GAW) programme to ensure long - term measurements in order to detect trends in global distributions of chemical constituents in air and the reasons for them (WMO, 2001a). With respect to aerosols, the objective of GAW is to determine the spatio - temporal distribution of aerosol properties related to climate forcing and air quality on multi - decadal time scales and on regional, hemispheric and global spatial scales. The objective of GAW Report No. 153, published in 2003, was to provide a synthesis of methodologies and procedures for measuring the ...
Guide to Information Technology Security
The purpose of this publication is to provide the reader with a broad overview of the main information technology security (ITS) components and procedures.

Ocean, climate and weather: the role of the World Meteorological Organization
When it comes to the weather, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70 per cent of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. The ocean is also a major driver of the global economy, carrying more than 90 per cent of world trade and sustaining the 40 per cent of humanity that lives within 100 km of the coast. Recognizing this, national weather agencies and researchers regularly monitor the ocean, model how it affects the atmosphere and deliver m ...

Weather, Climate and Hydrological services: how WMO supports the 2030 agenda for sustainable development
Weather, climate and water can either disrupt sustainable development or advance it. The providers of weather, climate, hydrological, marine and related environmental services therefore have a critical role to play in assisting countries to implement the 2030 Agenda and the Sustainable Development Goals (SDGs). High-quality meteorological services empower decision-makers to better manage agriculture, public health, water resources, energy production, transportation and other sectors that are critical for national development.

Climate Services for Supporting Climate Change Adaptation : Supplement to the Technical Guidelines for The National Adaptation Plan Process
World Meteorological Organization (WMO) ; Global Framework for Climate Services (GFCS) - WMO, 2016 (WMO-No. 1170)Because of the current and projected impacts on climate due to the high levels of greenhousegas (GHG) emissions, adaptation is a necessary strategy at all scales in a changing climate. At its 17th session, the Conference of Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) established the National Adaptation Plan (NAP) process as a way to facilitate effective adaptation planning in Least Developed Countries (LDCs) and other developing countries. The four key elements that need to be undertaken in the development of NAPs are: Laying the groundwork and addressin ...
WMO Statement on the status of the global climate in 2015
The year 2015 will stand out in the historical record of the global climate in many ways. Modern records for heat were broken: 2015 was a record warm year both globally and in many individual countries. Heatwaves were extremely intense in various part of the world, leading to thousands of deaths in India and Pakistan. Record extreme precipitation led to flooding that affected tens of thousands of people across South America, West Africa and Europe. Dry conditions in southern Africa and Brazil exacerbated multi-year droughts. The influence of the strong El Niño that developed in the later part ...

Climate Services for the Energy Sector: A New Priority Area for the GFCS
Energy systems are the engine of economic and social development. Their investments represent a sizeable portion of a country’s GDP. Indeed, energy is essential to practically all aspects of human welfare, including access to water, agricultural productivity, health care, education, job creation and environmental sustainability. Furthermore, energy sector emissions, such as CO2, account for the largest share of global anthropogenic greenhouse gas (GHG) emissions. Emissions reduction targets under the UN Framework Convention on Climate Change (UNFCCC) are expected to significantly increase dema ...

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.11: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2014
The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mole fractions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2014, with CO2 at 397.7±0.1 ppm, CH4 at 1833±1 ppb[2] and N2O at 327.1±0.1 ppb. These values constitute, respectively, 143%, 254% and 121% of pre-industrial (1750) levels. The atmospheric increase of CO2 from 2013 to 2014 was close to that averaged over the past 10 years. For both CH4 and N2O the increases from 2013 to 2014 were larger than that observed from 2012 to 2013 and ...
