Condensation Trails Over London and River Thames, United Kingdom

51.5N 0.7E

October 26th, 2010 Category: Clouds, Rivers, Sediments

UK - October 21st, 2010

Linear white condensation trails (or contrails) are visible in the air above London (left edge), the River Thames and the Thames Estuary, in England. Sediments from the river fill the estuary and pour out into the North Sea.

The condensation trails are white lines of clouds that form when water molecules cluster around airplane exhaust. The ones visible here are mostly likely from planes flying to or from one of London’s airports.

Condensation Trails Over Nova Scotia and New Brunswick, Canada

46.0N 65W

October 24th, 2010 Category: Clouds, Sediments

Canada - October 14th, 2010

The air above the Canadian provinces of Nova Scotia (right) and New Brunswick (left) is criss-crossed by airplane condensation trails (or contrails). These linear streaks form when water molecules gather around the exhaust released into the air by airplanes.

Also of note, although partially obscured by the contrails, are the rusty red sediments in Cobequid Bay (right) and Cognecto Bay (left), two inlets of the Bay of Fundy. As the sediments disperse into the bay, the water fades from red to green to blue.

Toyama City and Noto Peninsula, Japan

Noto Peninsula is a peninsula that projects north into the East Sea from the coast of Ishikawa prefecture in central Honshū, the main island of Japan. Most of the peninsula and nearby lands appear forested and bright green, while cities such as Toyama, southeast of the peninsula, appear tan.

The city of Toyama is situated along the shores of the semi-circular Toyama Bay. Faint green sediments, best viewed in the full image, are present in the bay and spill outwards into the East Sea. The lower part of the image is crossed by vertical lines of clouds – condensation trails caused by passing airplanes.
