Earth Observations taken by the Expedition 22 Crew

ISS022-E-005807 (3 Dec. 2009) --- Cloud formations and sunglint near Italy are featured in this image photographed by an Expedition 22 crew member on the International Space Station. This view depicts the Calabria region of southern Italy ? the toe of Italy?s ?boot? ? outlined by the Ionian and Tyrrhenian Seas to the southeast and northwest respectively. The water surfaces present a mirror-like appearance due to sunglint. This phenomenon is caused by sunlight reflecting off the water surface directly back towards the crew member aboard the space station. The ISS was located over northwestern Romania, approximately 1,040 kilometers to the northeast of Calabria, when this image was taken. The Calabrian peninsula appears shortened and distorted due to the high viewing angle from the station. Such imagery is termed oblique, indicating that the view is not looking directly downwards towards Earth?s surface from the ISS (known as a nadir view). This highly oblique view also highlights two distinct cloud patterns over the Calabrian interior. Patchy, highly textured cumulus clouds are present at lower altitudes, while grey altostratus clouds are elongated by prevailing winds at higher altitudes. The Strait of Messina, just visible at upper right, marks the boundary between the coastlines of Italy and the island of Sicily.
