Greenbelt, MD – Glaciers and ice sheets move in unique and sometimes surprising patterns, as evidenced by a new capability that uses satellite images to map the speed of flowing ice in Greenland, Antarctica and mountain ranges around the world.
With imagery and data from Landsat 8, a joint mission of NASA and the U.S. Geological Survey, scientists are providing a near-real-time view of every large glacier and ice sheet on Earth.
The NASA-funded Global Land Ice Velocity Extraction project, called GoLIVE, is a collaboration between scientists from the University of Colorado, the University of Alaska, and NASA’s Jet Propulsion Laboratory in Pasadena, California.
NASA’s Orbiting Carbon Observatory-2 Satellite data used to make Global Carbon Dioxide Emissions Maps
Written by Alan Buis
Pasadena, CA – Scientists have produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations of the greenhouse gas.
The maps, based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions.
No satellite before OCO-2 was capable of measuring carbon dioxide in fine enough detail to allow researchers to create maps of human emissions from the satellite data alone. Instead, earlier maps also incorporated estimates from economic data and modeling results.
Nashville, TN – White County is the latest in Tennessee to be quarantined for an invasive pest targeting ash trees.
Officials have detected Emerald Ash Borer (EAB) in the eastern section of White County. An adult EAB beetle was recently captured in a trap near Old Railroad Grade Road. With this discovery, White County joins 48 other counties in quarantine with a prohibition on the movement of ash trees and ash tree products.
Nashville, TN – An infestation of Emerald Ash Borer (EAB) has inched further across the state.
Officials have detected EAB in the Kimball area of Marion County, prompting a county-wide quarantine prohibiting the movement of ash trees and ash tree products.
This quarantine has now reached 48 counties in Tennessee. EAB is a destructive forest pest that was introduced from Asia into the United States in the 1990s.

Asia – As the Soldiers of Task Force Strike arrive in theater as part of Operation Inherent Resolve on their way to many different locations throughout Iraq, personnel here ensure they get to where they need to go at the time they are supposed to.
Many of the liaisons here deployed early, arriving in the country weeks before other Soldiers to ensure that the conditions would be set for the task force’s arrival.
“I deployed about three weeks ago” said CW1 Issac German, Task Force Strike mobility warrant officer. “My duty is to get all the Strike personnel and equipment from Fort Campbell to their end location, wherever that may be.”

Washington, D.C. – For more than three decades NASA has focused its space-faring skills and science chops CSI-like on an elusive global killer. Later this month, that pursuit takes us to East Asia. In a few years, part way to the moon.
We are getting close.
Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available.

Pasadena, CA – The tropical Pacific Ocean isn’t flat like a pond. Instead, it regularly has a high side and a low side. Natural cycles such as El Niño and La Niña events cause this sea level seesaw to tip back and forth, with the ocean near Asia on one end and the ocean near the Americas on the other.
But over the last 30 years, the seesaw’s wobbles have been more extreme, causing variations in sea levels up to three times higher than those observed in the previous 30 years. Why might this be?
AAA urges Americans to be informed when shaping 2016 travel plans
Knoxville, TN – Media publicity regarding terrorism, the stock market, and now the Zika virus is weighing on the minds of travelers, many of whom are turning to AAA for advice on whether they should alter their vacation plans.
AAA always encourages Americans to be cautious when traveling the world, and to be aware of any health or security alerts before leaving. Although much has been made about the Zika virus, and travelers should stay informed, Federal health officials have not issued travel restrictions to those countries with active virus transmission.

Pasadena, CA – Nepal’s magnitude 7.8 Gorkha earthquake caused significant damage and loss of life in 2015. In natural disasters like this, it is critical to locate areas that are in the most need of assistance as fast as possible.
Quickly assessing and communicating where the hardest-hit areas are and prioritizing which regions or communities have the greatest need for first-response teams is difficult when a disaster unevenly devastates various parts of a large area. It helps to get a bigger-picture view of where the damage is located from a high vantage point: low-Earth orbit.

Pasadena, CA – The current strong El Niño brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.
El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.
The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at:
