Greenbelt, MD – A volcano erupting and spewing ash into the sky can cover nearby areas under a thick coating of ash and can also have consequences for aviation safety. Airline traffic changes due to a recent volcanic eruption can rack up unanticipated expenses to flight cancellations, lengthy diversions and additional fuel costs from rerouting.
Airlines are prudently cautious, because volcanic ash is especially dangerous to airplanes, as ash can melt within an operating aircraft engine, resulting in possible engine failure.

Clouds are among the most important mediators of heat reaching Earth’s surface. Where clouds are absent, darker surfaces like the ocean or vegetated land absorb heat, but where clouds occur their white tops reflect incoming sunlight away, which can cause a cooling effect on Earth’s surface.

Kansas City, MO – With the arrival of the outdoor recreation season, the U.S. Army Corps of Engineers, Kansas City District reminds outdoor enthusiasts and recreationalists to be weather aware when visiting Corps lakes and recreation areas.
The National Weather Service advises the public that the best protection from weather-related injury or death is to monitor the weather and postpone or cancel outdoor activities when inclement weather is in the forecast.

Pasadena, CA – Jason-3, a new U.S.-European oceanography satellite mission with NASA participation, has produced its first complete science map of global sea surface height, capturing the current signal of the 2015-16 El Niño.
The map was generated from the first 10 days of data collected once Jason-3 reached its operational orbit of 830 miles (1,336 kilometers) last month. It shows the state of the ongoing El Niño event that began early last year. After peaking in January, the high sea levels in the eastern Pacific are now beginning to shrink.

Greenbelt, MD – Severe weather moved through the southern U.S. on February 2nd and 3rd, and NASA’s Global Precipitation Measurement or GPM core satellite examined the violent thunderstorms.
On February 3rd, 2016 at 1851 UTC (1:51pm ET/12:51pm CT) the GPM core observatory satellite flew over a line of storms extending from the Gulf coast of Florida through New York state. Tornadoes were spotted in Georgia and South Carolina within this area of violent weather.

Washington, D.C. – Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much.
Vandenberg Air Force Base, CA – On January 17th, 2016 at 10:50am PT/12:50pm CT, a SpaceX Falcon 9 rocket lifted off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft.
NASA launched Jason-3 into orbit for NOAA, the National Oceanic and Atmospheric Administration, the French space agency and EUMETSAT, the European Organization for the Exploitation of Meteorological Satellites.

Washington, D.C. – Jason-3, an international mission led by the National Oceanic and Atmospheric Administration (NOAA) to continue U.S.-European satellite measurements of the topography of the ocean surfaces, is scheduled for launch from Vandenberg Air Force Base in California on Sunday, January 17th.
Liftoff aboard a SpaceX Falcon 9 rocket from Vandenberg’s Space Launch Complex 4 East is targeted for 10:42:18am PST (12:42:18pm CST) at the opening of a 30-second launch window. If needed, a backup launch opportunity is available on the Western Range on January 18th at 10:31:04am PST (12:31:04pm CST).

Pasadena, CA – The amount of methane gas escaping from the ground during the long cold period in the Arctic each year and entering Earth’s atmosphere is likely much higher than estimated by current carbon cycle models, concludes a major new study led by San Diego State University and including scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California.
On November 12th, 2015, NASA’s Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) completed its final aircraft flight.

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:
