Satellite captures first-of-a-kind cloud image

by | Jun 27, 2024 | Climate Change

A never-seen-before space image of the interior structure of a storm cloud has been released by the European and Japanese space agencies.Their Earthcare satellite used a Doppler radar to capture the view.The data reveals the density of ice, snow, and rain in the cloud, as well as the speed with which these particles are falling to Earth.The novel Earthcare mission was launched in May to better understand how clouds influence the climate.Scientists expect the €850m (£725m) spacecraft’s observations to also improve weather forecasts.The type of image it produces is routinely acquired by research planes and from ground installations, but not from orbit.”I am absolutely thrilled to see the first radar images from Earthcare – for the first time ever we can measure the fall speeds of ice crystals, raindrops and snowflakes around the whole globe, not just at a handful of ground-based radar stations,” said Dr Robin Hogan, a mission scientist from the European Centre for Medium-Range Weather Forecasts (ECMWF).”This is a great technological achievement: we are using the tiny Doppler shift in the radar echo to infer fall speeds of only around one metre-per-second, and this is from a satellite that is hurtling round its orbit at 7km/s,” he told BBC News.The sample cloud was observed over the Pacific Ocean, just east of Japan, on 13 June.It’s possible to see in the image where exactly the different phases of water are being held. Larger particles are in the centre of the cloud.Velocity m …
