![]() ![]() Navigation is automated with single clicks of a mouse, or by typing in any location to automatically zoom in to see it. Additional guides and features can be accessed through a simplified menu. All one needs to control World Wind is a two button mouse. Primary features include the dynamic access to public domain imagery and its ease of use. It displays the sunrise and sunset times and solar angles for any point on the earth. It uses the Emxsys WorldWindJS library to display a 3D globe with terrain and imagery as well as 2D maps. There have been more than 20 million downloads to date, and the software is being used heavily by the Department of Defense due to the code's ability to be extended and the evolution of the code courtesy of NASA and the user community. The WorldWind Explorer is a geospatial web app for visualizing the earth. In addition to Earth, World Wind can also visualize other planets, and there are already comprehensive data sets for Mars and the Earth's moon, which are as easily accessible as those of Earth. The program overlays NASA and USGS satellite imagery, aerial photography. World Wind allows users to zoom from satellite altitude down to any place on Earth, leveraging high-resolution LandSat imagery and SRTM (Shuttle Radar Topography Mission) elevation data to experience Earth in visually rich 3D. The WorldWind Java version was awarded NASA Software of the Year in November 2009. states in mid-May 2022.Ames Research Center, Moffett Field, California Plumes of dust recently reached Florida, Texas, and other southern U.S. Those summer seasonal wind patterns can carry the dust from Africa to the Caribbean and the Gulf of Mexico. Dust storms in the summer tend to loft material higher into the atmosphere, allowing plumes to travel thousands of kilometers on high-level winds. If that is null or undefined, the default WorldWind Bing Maps key is used, but this fallback is provided only for non-production use. If null or undefined, the key at WorldWind.BingMapsKey is used. In winter and spring storms, Saharan dust often ends up fertilizing the nutrient-poor soils of the Amazon rainforest. bingMapsKey: String: The Bing Maps key to use for the image requests. Atlas: NASA World Wind 7 including Geoscience Australia's World Wind 476 J. The Sahara Desert is by far Earth’s largest source of airborne dust, and the storms can arise at any time of year. Latest Earth Amazing Earth: Satellite Images from 2021 In 2021, NASA’s fleet of Earth-observing satellites, as well as and instruments and astronauts on the International Space Station, captured some compelling moments on our planet. 11th IFIP WG 5.11 International Symposium, ISESS 2015, Melbourne, VIC. And dust-rich with iron and other minerals that plants and phytoplankton need-provides natural fertilizer for ocean ecosystems and lands downwind. Dust can degrade air quality and have negative health effects, particularly for people with lung conditions. The airborne particles absorb and reflect sunlight-altering the amount of solar energy reaching the surface-and can also promote or reduce cloud and storm formation, depending on other atmospheric conditions. Natural-color satellite imagery from May 30 to June 6 showed the storm’s progression across the water.ĭust plays a major role in Earth’s climate and biological systems. ![]() NASA satellite sensors that track aerosol optical depth observed substantial increases in sunlight-reflecting particles over the region starting on May 29 and continuing to June 6. NASA’s Earth Polychromatic Imaging Camera on NOAA’s DSCOVR satellite also acquired hemisphere-wide views of the event on June 3 and June 4.

Select near real-time products from the tables below. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 satellite acquired natural-color images (above) of dust on June 3 and 5, 2022, when the plumes were most distinct.

A fresh supply of dust was airlifted from the Sahara in early June 2022, and some of it appeared to be headed for the Americas. ![]() Winds pick up an estimated 100 million tons of dust from the Sahara Desert each year, and a sizable portion of it blows out over the North Atlantic Ocean. ![]()
