is cloud free and surface features such as coastlines, the snow-covered Alps and variations in the Northern Sahara desert surface are clearly visible. Geostationary satellites orbit at around 36,000 km above the Earth's surface and have an orbital period of one day, meaning they remain at a fixed

Tuesday will begin on a notably chilly note, particularly across northern and western regions. However, conditions will improve through the morning, with many areas enjoying a dry day accompanied by sunny spells. Some cloud may build during the afternoon, especially in central and eastern areas

Tuesday begins with areas of cloud and showery rain, some locally thundery, affecting central and southern regions. These outbreaks will gradually move north-eastwards, allowing increasing amounts of hot sunshine to develop across much of England and Wales by the afternoon. Scotland and Northern

The representation of solar and infra-red radiation, and its interaction with clouds in our numerical models.

Various radiative processes occur in the atmosphere: gases, aerosols, cloud droplets and ice crystals absorb radiation and emit thermal radiation. Aerosols, cloud particles and air molecules scatter radiation. The surface absorbs, reflects and emits radiation. The radiative properties

Tuesday will bring a continuation of changeable conditions across western parts of the UK, with cloud and outbreaks of rain or drizzle moving eastwards through the morning. The heaviest rainfall is expected over west-facing high ground, particularly across Wales, northern England, and southwest

This weekend’s weather offers a mix of autumnal cloud, sunshine, and chilly nights.

Saturday will begin on a cloudy note for much of the country, with the most persistent cloud and outbreaks of rain or drizzle affecting northern and north-western parts of Scotland. Breezy conditions will accompany the rain here, making for a rather damp and unsettled start. Across southern areas

, it will be a largely dry day with variable cloud and sunny intervals. The best of the sunshine will be across southern, central and eastern England, where it will feel very warm, with temperatures reaching 27–28°C in places. It will be warm across much of the country, away from the northwest

not routinely measured but important for model process understanding. Areas of key interest Measure updrafts, turbulence and dynamical structures in convective clouds on fine scales. Understand effect of pre-convective environment on subsequent storm development. Interaction between boundary layer structures
