current weather or environmental situations - for example, images of cloud-top height, fog coverage or ash clouds from a recent volcanic eruption. The image data can also be processed to form data-sets suitable for climate applications - for example, historical sea-surface temperature analyses

Thursday will bring largely settled conditions across the UK, with high pressure continuing to exert its influence. Most areas will remain dry, with the best of the sunshine expected in western regions. Elsewhere, cloud cover will gradually break up through the day, allowing sunny intervals
