Mongolia - May 2nd, 2011

Several bodies of water can be observed here, in Mongolia’s Great Lakes Depression. At the top of the image is Lake Uvs Nuur, whose surface is frozen and appears bright white.

South of Lake Uvs are Lake Khyargas, ice-free and dark turquoise in color and Lake Airag, smaller, also ice-free and mint-green in color.

Several other lakes can be observed near the bottom of the image, including Lake Khar, Lake Dörgön and Lake Khar-Us (right to left). Although these lakes appear mostly green in color, some patches of ice can be seen on the surface of Lakes Khar and Khar-Us.

Lake Uvs Nuur in Large Basin in Mongolia

Mongolia and Russia - July 30th, 2010

Lake Uvs Nuur is a highly saline lake in the Uvs Nuur Basin, an endorheic basin located mostly in Mongolia with a small part in Russia. It is the largest lake in Mongolia by surface area, covering 3,350 km² at 759 m above sea level. In the full image, swirls of sediments can be seen entering the lake from a rivermouth on its east shores.

The northeastern tip of the lake is situated in the Tuva Republic of the Russian Federation. A range of snow-capped mountains can be observed north of the lake, across the Russian border. In contrast to the green mountainous areas to the north, most of the land to the south in Mongolia appears flat and dry.

Smoke From Fires in Russia Blows South Towards Mongolia

Russia – June 28th, 2012

Hundreds of wildfires continue to burn across Russia, and more than 14 new fires have broken out over the past 24 hours (click here for previous images). While eleven of them have been put out, firefighters are still struggling to extinguish another 32 blazes. Authorities say the fires do not pose a threat to residential areas.

Here, smoke from fires north of the border area between Russia (above) and Mongolia (lower right) and Kazakhstan (lower left) can be observed blowing towards the south. Visible in the lower right quadrant is Mongolia’s Great Lakes Depression, including the large, rounded Lake Uvs Nuur.

Wildfire West of Krasnoyarsk Reservoir, Russia

Mongolia and Russia – May 31st, 2012

Many bodies of water can be observed in this image. In the upper part is the Krasnoyarsk Reservoir, created by the dam of the same name on the Yenisey River, in Russia. The Krasnoyarsk dam has greatly affected the local climate. Before the dam was built, the Yenisey in that area was free from ice around 196 days per year. Now it is free from ice the entire year up to 300 to 400 km downstream. The huge amount of water stored in Krasnoyarskoye reservoir makes the local climate more warm and humid.

Also of interest near the reservoir, to its west, is a wildfire (best observed at the top left of the full image). Smoke from the fire is blowing in a straight line towards the southwest.

Visible in the lower half of the image are several lakes in Mongolia: the rounded Lake Uvs Nuur, Lake Khyargas (below the former), Lake Airag (the small green lake just below Lake Khyargas), and, near the bottom edge from right to left, Lakes Khar, Dörgön and Khar-Us.

Mongolia - May 6th, 2012

As its name would suggest, Mongolia’s Great Lakes Depression contains several large bodies of water. Visible near the top edge is Lake Uvs Nuur, which appears bright white here as its surface is frozen.

In the center of the image, south of Lake Uvs, are Lake Khyargas (above) and Lake Airag (below). The former is significantly larger than the latter. It is dark blue in color, although the eastern half is slightly greener. The smaller Lake Airag is bright green.

Continuing south, several other lakes can be observed near the bottom of the image: Lake Khar, Lake Dörgön and Lake Khar-Us (right to left). These lakes show varying shades of blue, green and brown.
