WMO’s Global Atmosphere Watch (GAW) Programme is marking its 30th anniversary this year. The programme, which embraces about 100 countries, aims at forging an integrated global understanding of atmospheric composition and change. It coordinates observations across local to global scales, driving high quality and high-impact science while co-producing society relevant products and services.

Recent developments in the climate change arena, including the Paris Agreement in 2015 and the publication of the IPCC Special Report on Global Warming of 1.5 °C, have noted the potential need for negative emission technologies to remove carbon dioxide from the atmosphere in order to limit temperature increase.

Increasing levels of airborne pollutants deposited either through gravity (i.e. free-falling) or washed out by rain can result in detrimental effects to crops, human health and vulnerable ecosystems by altering critical and delicate chemical balances. Identifying areas most at risk and which would most benefit from measures to control excessive pollutant load is crucial.

The full Scientific Assessment of Ozone Depletion is now available. It shows that actions taken under the Montreal Protocol have led to decreases in the atmospheric abundance of controlled ozone-depleting substances (ODSs) and the start of the recovery of stratospheric ozone.

A concerted campaign to boost weather, ice and atmospheric observations in some of the most remote and inhospitable parts on Earth started this week, with the launch of a three-month Special Observing Period in the Antarctic. With days getting longer, the summer is about to start on the Antarctic continent. November is the month when the austral field season begins. This summer, extra atmospheric and sea-ice measurements in addition to the routine observations will be carried out as a contribution to the Year of Polar Prediction (YOPP).

An Arctic summer special observing period is taking place from 1 July to 30 September as part of the Year of Polar Prediction (YOPP). Extensive extra observations will be carried out at numerous land stations in the Arctic as part of field campaigns and expeditions, and by autonomous instruments. Numerical experimentation and internationally coordinated verification activities will use the additional observations for forecast evaluation and observational impact studies.
