China, Russia, Japan - October 8th, 2011

Smoke from wildfires hangs over the China-Russia border and extends out over the Sea of Japan. Air currents cause the smoke to take on a spiral shape west of the Japanese island of Hokkaido.

Although the smoke reaches Japan, it does not appear to reach the Russian island of Sakhalin (above). The smoke is densest over Russia in the upper left corner of the image.

Sakhalin is a large island in the North Pacific, stretching from the center to the top center of this image. It is part of Russia, administered as part of Sakhalin Oblast.

Sakhalin is the largest island in Russia, at 948 km (589 miles) long, and 25 to 170 km (16 to 106 mi) wide, with an area of 72,492 km2 (27,989 sq mi).

Sakhalin is separated from the mainland by the narrow and shallow Mamiya Strait or Strait of Tartary, which often freezes in winter in its narrower part, and from Hokkaidō, Japan by the Soya Strait or Strait of La Pérouse.

Nearly two-thirds of Sakhalin is mountainous. Two parallel ranges of mountains traverse it from north to south, reaching 600–1500 m (2000–5000 ft).

Russia and Japan - July 26th, 2011

This FAPAR image shows the vegetation index of Japan’s Hokkaido island (right), part of the eastern coast of Russia (left) and the southern section of Russia’s Sakhalin island (above center).

The vegetation index ranges mostly from good (green) to high (rusty red). It is highest along the shoreline of the Russian mainland and further inland to the west (visible in the full image), where as very large area of high activity can be observed.

Japan- August 27th, 2010

This FAPAR image portrays the vegetation index of Japan.’s main two islands: Honshu (below) and Hokkaido (above). The country shows an almost uniformly good index, as it is mostly green in color.

Some areas further inland, near the mountains, and on the island of Hokkaido, appear rusty red. This indicates a high vegetation index. Very few areas of low photosynthetic activity, yellow in color, can be observed. They appear mostly limited to coastal cities, such as Tokyo.

Japan - June 6th, 2010

This image shows the western part of the island of Hokkaido, Japan. Most of the island appears green, with some snow-capped mountain ridges. Cities appear greyish in color.

Visible on the left side of the image is Mount Yōtei, an active stratovolcano located in Shikotsu-Toya National Park. It is also called Yezo Fuji or Ezo Fuji, because it resembles the more famous Mount Fuji, as both have a very conical shape. Here the summit of the volcano is capped in white snow, with green slopes below, and ringed by a tan area.

To the south of the volcano is Lake Tōya, a volcanic caldera lake in the same national park. The stratovolcano of Mount Usu lies on the southern rim of the caldera. It is a nearly circular lake with 10 kilometers diameter in the east-west direction and 9 kilometers in the north-south direction. A green island, Nakano-shima, stands out in the middle of the lake’s dark blue waters.
