Analysis of a 25-year satellite record shows that Earth has a persistent east–west albedo symmetry split at 27° E, with clear-sky albedo, cloud radiative effect and open-ocean fraction exhibiting a triple symmetry around this meridian.

A circle running along the 27° east and 153° west meridians divides the globe into two halves with equal reflectivity – and this may have implications for solar geoengineering…
