The World Weather Research Programme: A 10-year Vision
Weather, Climate, Information, Research, Observations, Polar, Floods, Oceans, Partnership, Drought
Bulletin nº Vol 64 (1) - 2015
Theme: Weather
3
Publish Date: 3 March 2015
Weather prediction has achieved immense progress, driven by research and increasingly sophisticated telecommunication, information technology and observational infrastructure. Predictive skill now extends in some cases beyond 10 days, with an increasing capability to give early warning of severe weather events many days ahead.
The Hydrometeorological Enterprise: The Benefits of Partnerships
Weather, Climate, Observations, Disaster risk reduction, Oceans, Floods, Partnership, Agriculture and food security
Bulletin nº Vol 64 (1) - 2015
Theme: Observations

Publish Date: 2 March 2015
A better understanding of key partners and users – and the type of information they need to prepare for and react to weather events – will increase the likelihood of success of the hydrometeorological enterprise as it works collectively to achieve its mission of saving lives and property.
Monitoring Ocean Carbon and Ocean Acidification

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.
Rescue, Archival and Stewardship of Weather Records and Data

Data repositories and archives play a critical role as the source for the observational data used in the study of weather and climate. After over two centuries of recording observations on paper, observations in the last 20 years have mostly been collected digitally. Creating homogeneous, complete data sets from disparate collections is a fundamental challenge facing the climate research community.
Is the Ozone Layer on the Mend? Highlights from the most recent WMO/UNEP Ozone Assessment
Environment, Observations, Polar, Greenhouse gases, Space

The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987, has been successful in that the amount of chlorofluorocarbons is now slowly diminishing. A common misunderstanding, however, is the belief that the ozone problem has been solved and the ozone layer is back to its original state.
Climate Services – Transitioning from CLIPS to GFCS
Weather, Environment, Research, Observations, Information, Data exchange, Climate services, Forecast, Disaster risk reduction
Bulletin nº Vol 64 (1) - 2015
Theme: Climate

Publish Date: 2 March 2015
The present Global Framework for Climate Services (GFCS) with a vision “to enable society to better manage the risks and opportunities arising from climate variability and change, through the development and incorporation of science-based climate information and prediction into planning, policy and practice” carries forward and builds on the solid foundation laid by the Climate Information and Prediction Services (CLIPS) project.
In this Issue: Climate Knowledge for Climate Action

WMO ranked 2014 as the hottest year on record. In 2015, the United Nations Member States will adopt three major agreements that relate to the environment. The first, in March, is in the area of disaster risk reduction. The second, in September, will promote sustainable development. The third, in December, aims to limit average global temperature increases and the resultant climate change.
Progress in Observing and Predicting ENSO

Governments, private companies and individuals are demanding ever more sophisticated climate services, as manifested by the Global Framework for Climate Services (GFCS). But parts of the ocean observation network – paramount to the delivery of climate services – are at risk, and the evolution of climate prediction systems is not keeping pace in terms of accuracy and reliability. We are at a critical stage in observing and predicting the El Niño-Southern Oscillation (ENSO).
Preparing the Use of New Generation Geostationary Meteorological Satellites

Seven new generation geostationary satellites will be launched into positions over the equator within the next five years. These launches will drastically change the Space Component of the WMO Integrated Global Observing System (WIGOS) and National Meteorological and Hydrological Services are challenged to prepare for the advanced capabilities the satellites will offer. The imager capabilities, sampling rate, spectral resolution and spectral channels, of this new generation of satellites will drastically increase data rates – by an order of up to 100. All National Meteorological Hydrological...
Observing the Global Atmosphere by Instrumented Passenger Aircraft – The Story of IAGOS
Weather, Observations, Research, Aviation, Greenhouse gases, Clouds, Water, Forecast
Bulletin nº Vol 63 (2) - 2014
Theme: Observations

Publish Date: 3 November 2014
The In-service Aircraft for a Global Observing System (IAGOS) uses commercial passenger aircraft as a platform for the measurement of the composition of the atmosphere. It is one component of the European Research Infrastructure for gathering long-term, routine in-situ observational data on the state of the atmosphere.
