NASA - National Aeronautics and Space AdministrationPasadena, CA – A NASA-produced map showing areas of eastern Puerto Rico that were likely damaged by Hurricane Maria has been provided to responding agencies, including the Federal Emergency Management Agency (FEMA).

The hurricane, a Category 4 storm at landfall on Puerto Rico on September 20th, caused widespread damage and numerous casualties on the Caribbean island, an unincorporated U.S. territory with a population of about 3.4 million.

NASA - National Aeronautics and Space AdministrationPasadena, CA – A venerable U.S./European oceanography satellite mission with NASA participation that has expanded our knowledge of global sea level change, ocean currents and climate phenomena like El Niño and La Niña will take on an additional role next month: improving maps of Earth’s sea floor.

The Ocean Surface Topography Mission (OSTM)/Jason-2 satellite, a partnership among NASA, the National Oceanic and Atmospheric Administration (NOAA), the French Space Agency Centre National d’Etudes Spatiales (CNES) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), marked its ninth year in orbit on June 20th, 2017.

NASA Study reveals Antarctic Glacier’s Ice Loss May Not Progress as Quickly as Thought

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The melt rate of West Antarctica’s Thwaites Glacier is an important concern, because this glacier alone is currently responsible for about 1 percent of global sea level rise. A new NASA study finds that Thwaites’ ice loss will continue, but not quite as rapidly as previous studies have estimated.

The new study, published in the journal Geophysical Research Letters, finds that numerical models used in previous studies have overestimated how rapidly ocean water is able to melt the glacier from below, leading them to overestimate the glacier’s total ice loss over the next 50 years by about 7 percent.

NASA studies changes in Cloud Heights

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new analysis of 15 years of NASA satellite cloud measurements finds that clouds worldwide show no definitive trend during this period toward decreasing or increasing in height. The new study updates an earlier analysis of the first 10 years of the same data that suggested cloud heights might be getting lower.

Clouds are both Earth’s cooling sunshade and its insulating blanket. Currently their cooling effect prevails globally. But as Earth warms, the characteristics of clouds over different global regions — their thickness, brightness and height — are expected to change in ways that scientists don’t fully understand.

Climate change may eventually change global cloud heights, but scientists need a longer data set to know whether that's happening already. (NASA)

Dodging the Roadkill: Dear Hotels, We need to talk about your Wi-Fi

 

Dodging the Roadkill - A Biker's JourneyClarksville, TN – We all have our favorite hotel chains. We each have different needs and expectations when we travel. But the one thing that is absolutely imperative for me is the internet.

I’m writing stories on the road and I need a good connection. But not only that, we ALL could use good WI-FI for all of our social media and email.

Most hotels fail miserably.

When I bought my motorcycle and started traveling, I immediately noticed that the “free Wi-Fi” advertised by the hotels I stayed in was a miserable excuse for bandwidth. It took forever to connect, took forever to load the page, and watch a video or live stream?

“Fuh-get-about it!”

Why is there a lack of good internet connections today at hotels.

NASA says 2016 Quake Study may alter Earthquake Hazard Models

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Last November’s magnitude 7.8 Kaikoura earthquake in New Zealand was so complex and unusual, it is likely to change how scientists think about earthquake hazards in plate boundary zones around the world, finds a new international study.

The study, led by GNS Science, Avalon, New Zealand, with NASA participation, is published this week in the journal Science. The team found that the November 14th, 2016, earthquake was the most complex earthquake in modern history. The quake ruptured at least 12 major crustal faults, and there was also evidence of slip along the southern end of the Hikurangi subduction zone plate boundary, which lies about 12 miles (20 kilometers) below the North Canterbury and Marlborough coastlines.

Two ALOS-2 satellite images show ground displacements from the Nov. 2016 Kaikoura earthquake as colors proportional to the surface motion in two directions. The purple areas in the left image moved up and east 13 feet (4 meters); purple areas in the right image moved north up to 30 feet (9 meters). (NASA/JPL-Caltech/JAXA)

NASA prepares for future Satellite by studying Coral Reefs of Hawaii

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA pulled off a scientific double play in Hawaii this winter, using the same instruments and aircraft to study both volcanoes and coral reefs. Besides helping scientists understand these two unique environments better, the data will be used to evaluate the possibility of preparing a potential future NASA satellite that would monitor ecosystem changes and natural hazards.

The advantages of studying active volcanoes from the air rather than the ground are obvious. Coral reefs may not offer the same risks in a close encounter that volcanoes do, but there’s another good reason to study them by remote sensing: they’re dotted across thousands of square miles of the globe.

NASA announces NOAA’s GOES-16 Satellite takes First Photos of Earth

 

Written by John Leslie
National Oceanic and Atmospheric Administration

NASA - National Aeronautics and Space AdministrationSilver Spring, MD – GOES-16, the first spacecraft in NOAA’s next-generation of geostationary satellites, has sent the first high-resolution images from its Advanced Baseline Imager (ABI) instrument. Included among them are a composite color full-disk visible image of the Western Hemisphere captured on January 15th, 2017.

Created using several of the ABI’s 16 spectral channels, the full-disk image offers an example the satellite’s advanced technology.

This composite color full-disk visible image of the Western Hemisphere was captured from NOAA GOES-16 satellite at 1:07 pm EST on Jan. 15, 2017 and created using several of the 16 spectral channels available on the satellite's sophisticated Advanced Baseline Imager. The image, taken from 22,300 miles above the surface, shows North and South America and the surrounding oceans. (NOAA)

2016 Warmest Year on Record according to NASA, NOAA

 

Written by Sean Potter
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Earth’s 2016 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 2016 were 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures.

The 2016 temperatures continue a long-term warming trend, according to analyses by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

2016 was the hottest year on record, continuing a decades-long warming trend. Scientists at NASA’s Goddard Institute for Space Studies (GISS) analyzed measurements from 6,300 locations and found that Earth’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late-19th century, largely a result of human emissions into the atmosphere.

NASA’s AIRS Instrument Tracks Series of Storms Battering California

NASA - National Aeronautics and Space AdministrationPasadena, CA – A series of atmospheric rivers that brought drought-relieving rains, heavy snowfall and flooding to California this week is highlighted in a new movie created with satellite data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite.

The images of atmospheric water vapor were collected by AIRS between January 7th and 11th. They show the amount of moisture present in the atmosphere and its movement across the Pacific Ocean to the United States, where much of it fell as rain or snow.
