Measuring radiation with aircraft

By Peter Hill In my career as an atmospheric scientist I’ve relied on observational data from a wide range of sources including satellite imagery, surface measurements, ground-based and satellite based radar, and aircraft measurements. Last July I had my first … Continue reading

Geoengineering – how could we detect its cooling effect?

By Eunice Lo Sulphate aerosol injection (SAI) is one of the geoengineering proposals that aim to reduce future surface temperature rise in case ambitious carbon dioxide mitigation targets cannot be met.  Climate model simulations suggest that by injecting 5 Tg of sulphur dioxide gas … Continue reading

The interaction between aerosols and clouds

By Nicolas Bellouin As part of the Copernicus Atmosphere Monitoring Service (CAMS), I lead an activity that will provide in August new estimates of radiative forcing of climate due to changes in atmospheric composition. One of the radiative forcing mechanisms … Continue reading

How do emissions in Abidjan affect the price of chocolate in the UK?

By Peter Hill The majority of the cocoa beans required to supply the world’s ever increasing demand for chocolate come from southern West Africa. Unfortunately, the volume produced, and consequently the cost of cocoa beans, is heavily dependent on the … Continue reading

Ah, the sweet smell of rain …

By Ellie Highwood Despite all the rain of the past winter, there is something about rain that I have missed – its perfume. As we head towards spring, with daffodils all around us already, I am looking forward to the … Continue reading

Volcanoes as rain magnets

By Geoff Wadge When we have a very large volcanic eruption (as for example Mt Pinatubo in 1991) it gets global news coverage, not least because of its potential to perturb the climate. Whether smaller eruptions get widely noticed usually … Continue reading

Climate change and the Indian monsoon: another emissions problem

By Andy Turner I wrote a year or so ago about the forecast for the (then) forthcoming summer monsoon season. India was worried about the possible effect of a predicted El Niño on the rainfall total; El Niño is normally associated … Continue reading

Unravelling the complexity of aerosol-cloud interactions – the value of going back to basics

By Ellie Highwood State-of-the art climate models used for future projections of climate change have become huge tangled webs of code representing thousands of physical processes. In many of these processes, we have to simplify or in some cases even … Continue reading
