Supercomputer recreates one of Earth's most famous images

Fifty years ago today, astronauts on Apollo 17, NASA's last crewed mission to the Moon, pulled an iconic photo of our planet. The image became known as the Blue Marble and is the first fully illuminated color image of Earth taken by a human. blue marble

Now, the scientists recreated this image during a test run of a state-of-the-art digital climate model. The model can simulate climate phenomena such as storms and ocean eddies at a resolution of 1 km, up to 100 times sharper than standard global simulations.

To recreate the swirling winds in the new Blue Marble image – including a cyclone over the Indian Ocean – the researchers fed meteorological data from 1972 into software running on a supercomputer.

The resulting image shows distinctive features of each region, such as high tides off the coast of Namibia and long cloud cover.

Experts say the image highlights the increasing complexity of high-resolution climate models. These are expected to form the core of the European Union's Destination Earth project, which aims in the creation of a "digital twin" of the Earth to better predict extreme weather conditions and guide preparedness plans.
