GAW Report, 239. Calibration Methods of GC-μECD for Atmospheric SF6 Measurements
SF6 is a substance which originates only from anthropogenic sources used primarily in the electricity and electronics supply industries, e.g. the semiconductor industry, where it is used as an electronic insulator due to its inertness. SF6 is a trace gas that exists in small quantities at the level of ppt (parts-per-trillion, 1/1012) in the atmosphere, but its global warming potential is 23,500 times greater than that of CO2 when compared over a 100-year period[1]. In particular, SF6 has an atmospheric lifetime of 3,200 years upon emission, and will eventually exacerbate the man-made greenhous ...

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 ...International Cloud Atlas Web edition

IOM Report, 126. Quality Assessment using METEO-Cert : The MeteoSwiss Classification Procedure for Automatic Weather Stations
It this report, METEO-Cert and its application is described. The METEO-Cert process assigns qualitative flags to each station and its instruments. Those qualitative flags provide valuable information on the applicability of the measured data and help to identify potential improvement of the station’s exposure.
Priority Needs for the Operationalization of the Global Framework for Climate Services (2016–2018)
The global community is rapidly putting in place measures to protect societies from adverse socioeconomic and environmental impacts caused by extreme weather-, climate- and water-related events, and also to take maximum advantage of any positive benefits of these changes that may exist. However, many projects are being undertaken in isolation, in the absence of mechanisms for alignment of the diverse efforts being made at project level, and without conforming to relevant international standards. This can result in duplication of efforts, which may prove unsustainable or ineffective in the long ...
A Proposed Long Term Resource Plan for Climate Data Management and Rescue Activities
In response to WMO’s Executive Council’s decision at its sixty-eighth session, June 2016 (Decision 39 (EC-68)) this paper presents a proposed resource plan for the sustainable support of climate data management systems (CDMS) and data rescue activities (the Plan). The initial focus in this Plan is on undertaking or supporting climate data rescue and CDMS implementation over the next five years, in developing and least-developed countries (D & LDC) that have recently expressed their need for assistance with securing and managing their data. Most of these countries are in Regions I, V and the In ...

WMO Guidelines on Generating a Defined Set of National Climate Monitoring Products
The aim of this publication is to provide a specification for the shortlist of NCMPs that can be produced consistently and easily by most countries. By having clearly defined NCMPs, it should be possible for countries with fewer resources to focus their efforts on a small number of products that have wide applicability and interest.World Meteorological Day 2017 highlights

WWRP, 2016-4. Catalysing Innovation in Weather Science: WWRP Implementation Plan 2016-2023
Weather-related disasters pose a major threat to society, the environment and the economy. As the vulnerability to weather related hazards increases due to climate change, growing population, urbanization and other factors it is imperative to coordinate weather research targeted towards improving forecasts and warnings at international level. The impacts resulting from the underpinning hydro-meteorological events such as heat waves, droughts, floods, landslides, wind storms, landfalling tropical cyclones or severe convective storms are regional or local in nature. Many of these disasters, howe ...Cap cloud over volcano Teide

Miller Jack - WMO, 2016"This is my first time-lapse film I decided to put together. All scenes are shot in Florida from April - September 2016. This film is meant to showcase Florida's weather pattern from a stray shower to a fierce severe warned thunderstorm.
Through that time period, I had taken over 149,000 photos between the two cameras for this project. Less than half were used for the final production. Overall editing took about 2 months and was really because of the music choice as I had switched songs half way through the project.

IOM Report, 101. Guidance on Instrumentation for Calibration Laboratories, including Regional Instrument Centres
Users of meteorological observations have increasing needs for high quality meteorological and hydrological data. The traceability of these data to the International System of Units (SI) standards is needed to ensure their quality and to meet the users’ requirements. Regional Instrument Centres, as well as NMHSs calibration laboratories are essential in ensuring data quality by providing calibration of the standards and traceability to SI. CIMOXIV recognized that RICs needed guidance on how to build calibration laboratories and purchase calibration equipment to strengthen their capabilities. T ...

The current survey is the third in its category. It was built on the two previous surveys that were conducted by CIMO 10 and 20 years ago. Since then, the automatic stations have been providing an increased percentage of precipitation data, snow water equivalent, and depth of snow on the ground. The CIMO, at its 14th session, initiated this review to assess the methods for measurement and obse ...
IOM Report, 103. Evaluation Scheme for Regional Instrument Centres and Other Calibration Laboratories
The calibration of instruments and the traceability of meteorological measurements to the International Standard (SI) of units are crucial to ensure the quality of meteorological observations and to meet the users’ requirements. Regional Instrument Centres (RICs) play a key role in this context, by providing calibration services to other Members of their Region. In view of the need to ensure the quality of the services provided by the RICs, and the need for strengthening of RICs, the WMO Executive Council requested CIMO to develop a mechanism for their continuous evaluation to ensure quality o ...

SP, 05. The potential role of WMO in Space Weather : a report on the potential scope, cost and benefit of a wmo activity in support of International coordination of space weather services, prepared for the sixtieth executive council
The present report addresses the possible scope, cost and benefit of initiating a WMO activity in the area of Space Weather. The expression Space Weather is used to designate processes occurring on the Sun, in the magnetosphere, ionosphere and thermosphere, which have the potential to affect the near-Earth environment. These processes occurring mainly outside of the atmosphere are not meteorological phenomena, and thus haven’t so far been considered within the mandate of WMO. However, because of their importance and possible synergy with activities under WMO’s responsibility, the issue o ...
