            "description": "The Antarctic ozone hole is caused by human-produced chlorine-containing chlorofluorocarbons (CFCs) and bromine-containing halons. These compounds had a variety of commercial uses, including hair sprays, refrigerants, and fire suppressants.This story about the cause of ozone depletion was originally developed for the NASA hyperwall, where nine different animations can be shown simultaneously. The animations shown here are derived from the Goddard Earth Observing System (GEOS) model and cover two periods. The first period is from August through November 2004, and the second is from December 2004 through March 2005. The first period animations are shown on this page. The second period animations may be downloaded through the Download links below.The chlorine compounds that destroy ozone have now been regulated under the international Montreal Protocol agreement. Because of this agreement, the ozone hole is projected to disappear around 2060-2070. NASA and the international community continue to monitor Antarctic ozone. || ",

            "description": "This new space-based view of Earth's city lights is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. The data was acquired over nine days in April 2012 and thirteen days in October 2012. It took the satellite 312 orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth's land surface and islands. This new data was then mapped over existing MODIS Blue Marble imagery to provide a realistic view of the planet.The view was made possible by the \"day-night band\" of Suomi NPP's Visible Infrared Imaging Radiometer Suite. VIIRS detects light in a range of wavelengths from green to near-infrared and uses \"smart\" light sensors to observe dim signals such as city lights, auroras, wildfires, and reflected moonlight. This low-light sensor can distinguish night lights tens to hundreds of times better than previous satellites. || ",

A cloud's optical thickness is a measure of attenuation of the light passing through the atmosphere due to the scattering and absorption by cloud droplets. Clouds do not absorb visible wavelengths of sunlight; rather, clouds scatter and reflect most visible light. Here, light blue shades indicate areas where there are low cloud-optical-thickness values, while red and orange shades indicate high values (i.e., greater attenuation caused by the scattering and absorption from cloud droplets). The higher a cloud's optical thickness, the more sunlight the cloud is scattering and reflecting. || ",

On a clear night, our galaxy—the Milky Way—can be seen by the naked eye, but because our eyes cannot distinguish the individual stars that make up the glowing band of light, it appears “milky.” Infrared telescopes, however, see with different “eyes,” capable of detecting various wavelengths (outside the visible range) that provide unprecedented views of our Galaxy and beyond. This not-so-milky image of the Milky Way—nearly free of the obscuring effects of interstellar dust—was made with data from two highly automated 1.3 m ground-based telescopes used during the Two Micron All Sky Survey (2MASS) project. 2MASS is a joint project of the University of Massachusetts in Amherst and the Infrared Processing and Analysis Center at the California Institute of Technology. 2MASS has uniformly scanned the entire sky in three near-infrared bands, using two highly-automated 1.3-meter telescopes, one at a northern hemisphere facility and the other in a southern hemisphere facility. Images such as this, allow scientists to gain a better understanding of the structure of our Galaxy and the universe. || ",

The ocean color layer ranging from blue to orange depict air temperatures 2 meters (T2M) above sea level. Since Sea Surface Temperatures (SST) are typically measured at sea level and below, the T2M model output behaves somewhat differently. Nonetheless, it is a reasonable proxy to SST. Landcover information is taken from the Next Generation Blue Marble dataset. Sea Ice is depicted as solid white and clouds are shades of white.
