STS103-728-022 (19-27 December 1999)--- One of the astronauts aboard the Earth-orbiting Space Shuttle Discovery used a handheld 70mm camera to photograph the Tifernine dunes (note, the  dunes are below the "beak" of sandstone rock).  According to NASA scientists studying the STS-103 photo collection, the dunes were created when the dark sandstone rocks trapped sand.  Winds, they continued, then piled the sand into dunes up to 457.2 m (1,500 ft).  The color of the sandstone is due to a desert varnish, the scientists reported.  The varnish is composed of manganese, iron oxides, hydroxides, and clay minerals, they said.

The winter of 2013 was among the driest on record for California, setting the stage for an active fire season. By August 26, the Rim Fire had made its way into the record books. At just 15 percent contained, the fire is now the 13th largest in California since records began in 1932. Apart from being large, the fire is also threatening one of the United States’ greatest natural treasures: Yosemite National Park.  The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite tracked the growth of the fire between August 23 and August 26 in a series of nighttime images. The VIIRS day-night band is extremely sensitive to low light, making it possible to see the fire front from space. The brightest, most intense parts of the fire glow white, exceeding the brightness of the lights of Reno, Nevada to the north. Pale gray smoke streams north away from the fire throughout the sequence.  The perimeter of the fire grows from day to day along different fronts, depending on winds and fire fighting efforts. On August 24, fire fighters focused their efforts on containing the western edge of the fire to prevent it from burning into Tuolumne City and the populated Highway 108 corridor. They also fought the eastern edge of the fire to protect Yosemite National Park. These efforts are evident in the image: Between August 23 and 24, the eastern edge of the fire held steady, and the western edge receded. The fire grew in the southeast.  On the morning of August 25 fire managers reported that the fire was growing in the north and east. In the image, the most intense activity is just inside Yosemite National Park.  Fire fighters reported that the Rim Fire continued to be extremely active on its eastern front on the morning of August 26, and this activity is visible in the image. By 8:00 a.m., the fire had burned 149,780 acres. The fire forced firefighters in Yosemite National Park to take measures to protect the Merced and Tuolumne Groves of Giant Sequoias, but the National Park Service reported that the trees were not in imminent danger. While parts of the park are closed, webcams show that most of the park has not been impacted.  The Rim Fire started on the afternoon of August 17. It has destroyed 23 structures and threatened 4,500 other buildings. Its cause is under investigation.

The skies over northern China were shrouded with a thick haze in late December, 2013. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite captured this true-color image on December 23.  The dense, gray haze obscures almost all the land and much of the coastal waters from view south and east of the Taihang Mountains. Clearer air covers the region north of the mountains, although fingers of haze roll through most river valleys. The cities of Beijing and Hebei, both west of the Bohai Sea are complete enshrouded.  By December 24 the smog levels in some area exceeded World Health Organization-recommended levels by 30 times, according to Bloomberg News. The concentration of PM2.5, which are fine air particulates, were reported at 421 micrograms per cubic meter at 2 p.m. near Tiananmen Square in Beijing, while levels were 795 in Xi’an and 740 in Zhengzhou. The World Health Organization (WHO) recommends 24-hour exposure to PM2.5 concentrations no higher than 25 micrograms per cubic meter.  While not the sole cause of haze and pollution, the use of coal as a very cheap energy source adds to the problem, particularly north of the Huai River. Prior to 1980, the government policy provided free coal for fuel boilers for all people living north of the Huai River. The widespread use of coal allows people in the north to stay warm in winter, but they have paid a price in air quality.  According to Michael Greenstone, a Professor of Environmental Economics at Massachusetts Institute of Technology (MIT), whose research team published a paper on sustained exposure to air pollution on life expectancy in the region, air pollution, as measured by total suspended particulates, was about 55% higher north of the Huai River than south of it, for a difference of around 184 micrograms of particulate matter per cubic meter. The research, published in Proceedings of the National Academy of Sciences in July, 2013, also noted life expectancies were about 5.5 years lower in the north, owing to an increased incidence of cardiorespiratory mortality.  Air pollution is an on-going issue for the government of China, and Beijing’s Five-Year Clean Air Action Plan aims to reduce overall particle density by over 25 percent on the PM2.5 scale by 2017, and also takes aim at shutting down all coal-burning plants.

There was a time when the Northwest Passage was a sort of maritime Holy Grail, a route so desired and sought after, but so elusive. For most of the recorded history of North America, the Passage has been nearly impassable and often deadly. But with the modernization of ships and the warming of the Earth, cruising and sailing through the Canadian Archipelago from Baffin Bay to the Beaufort Sea has grown more common and easier. But it’s not necessarily easy.  The top image above shows the Northwest Passage as it appeared on August 31, 2015, to the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi-NPP satellite.

The remnant moisture from what was once Hurricane Patricia and moisture from the Gulf of Mexico were being transported north by a trough of low pressure over Wisconsin. The clouds and moisture were streaming into the Eastern third of the U.S. on October 28, 2015. The hybrid system was generating windy conditions which were seen from NASA's RapidScat instrument, while NOAA's GOES-East satellite captured an image of the impressive and sizeable cloud cover.
