International Space Station Imagery
The boot of Italy
high res (1.1 M) low res (66 K)
ISS006-E-33736 (25 February 2003) --- The boot of Italy crosses the image in this southwest-looking view taken by an Expedition Six crewmember onboard the International Space Station (ISS). The spine of Italy is highlighted with snow and the largely cloud-covered Mediterranean Sea is at the top. The Adriatic Sea transverses most of the bottom of the image and Sicily appears top left beyond the toe of the boot. The heel lies out of the left side of the image. Corsica and Sardinia appear right of center partly under cloud. The floor of the Po River valley, lower right, is obscured by haze. Experience gained from similar haze events, in which atmospheric pressure, humidity and visibility and atmospheric chemistry were known, suggests that the haze as industrial smog. Industrial haze from the urban region of the central and upper Po valley accumulates to visible concentrations under conditions of high atmospheric pressure and the surrounding mountains prevent easy dispersal. This view illustrates the markedly different color and texture of cloud versus industrial aerosol haze.
