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.

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 science community is concerned: many established researchers plan to retire in the coming decade and there is a dearth of early and mid-career researchers ready to take their place and contribute in a meaningful way. Unless young scientists are encouraged, trained and mentored in various scientific fields knowledge gaps will occur.

The United States has launched the first of its new generation of highly advanced polar-orbiting meteorological satellites. Known as JPSS-1 (for Joint Polar Satellite System), the new satellite is the first in a series of missions that the US is contributing to the space-based component of the WMO Integrated Global Observing System (WIGOS) through to 2038.

The lack of reliable, frequently updated information on the Earth’s polar ice caps is a significant problem for weather forecasting, affecting forecast skill for the entire planet. The poor numerical weather prediction (NWP) skill for the Arctic region and the Earth’s northern territories is caused primarily by errors in determining initial conditions, which depend on the quality of initial data.
