NASA reports NOAA’s GOES-16 Satellite begins mapping Lightning

NASA - National Aeronautics and Space AdministrationSilver Spring, MD – Detecting and predicting lightning just got a lot easier. The first images from a new instrument onboard NOAA’s GOES-16 satellite are giving NOAA National Weather Service forecasters richer information about lightning that will help them alert the public to dangerous weather.

The first lightning detector in a geostationary orbit, the Geostationary Lightning Mapper (GLM), is transmitting data never before available to forecasters. The mapper continually looks for lightning flashes in the Western Hemisphere, so forecasters know when a storm is forming, intensifying and becoming more dangerous. Rapid increases of lightning are a signal that a storm is strengthening quickly and could produce severe weather.

This is one hour of GOES-16's Geostationary Lightning Mapper (GLM) lightning data from Feb. 14, when GLM acquired 1.8 million images of the Earth. It is displayed over GOES-16 ABI full disk Band 2 imagery. Brighter colors indicate more lightning energy was recorded; color bar units are the calculated kilowatt-hours of total optical emissions from lightning. This is preliminary, non-operational data.

NASA’s Earth Science continues research from International Space Station

 

Written by Samson Reiny
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow.

Two new instruments are scheduled to make their way to the station on the SpaceX Dragon capsule.

The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the condition of the ozone layer, which covers an area in the stratosphere 10 to 30 miles (16 to 48 kilometers) above Earth and protects the planet from the sun’s harmful ultraviolet radiation.

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 - 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 advances Exploration Objectives in 2016

 

Written by Bob Jacobs / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.

“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”

NASA looks to use Satellite Observations of Earth’s Magnetic Fields to Measure Ocean Heat

 

Written by Kate Ramsayer
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task.

A surprising feature of the tides could help, however. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.

NASA’s International Space Station Rapid Scatterometer instrument ends operations

 

Written by Carol Rasmussen

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s International Space Station Rapid Scatterometer (ISS-RapidScat) Earth science instrument has ended operations following a successful two-year mission aboard the space station. The mission launched September 21st, 2014, and had recently passed its original decommissioning date.

ISS-RapidScat used the unique vantage point of the space station to provide near-real-time monitoring of ocean winds, which are critical in determining regional weather patterns. Its measurements of wind speed and direction over the ocean surface have been used by agencies worldwide for weather and marine forecasting and tropical cyclone monitoring.

NASA reports new study sheds light on slowdown of Global Warming

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new multi-institutional study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the Earth system, with Earth’s ocean absorbing the extra heat.

The phenomenon was referred to by some as the “global warming hiatus.” Global average surface temperature, measured by satellites and direct observations, is considered a key indicator of climate change.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA successfully launched for the National Oceanic and Atmospheric Administration (NOAA) the first in a series of highly advanced geostationary weather satellites Saturday from Cape Canaveral Air Force Station in Florida.

NOAA’s Geostationary Operational Environmental Satellite-R (GOES-R) lifted off at 5:42pm CST on its way to boost the nation’s weather observation capabilities, leading to more accurate and timely forecasts, watches and warnings.

The GOES-R satellite will be NOAA's most sophisticated weather observation spacecraft and is expected to improve forecasts and tracking substantially. (NASA/Kim Shiflett)

NASA to launch Six Small Satellites in new approach to studying Earth

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Beginning this month, NASA is launching a suite of six next-generation, Earth-observing small satellite missions to demonstrate innovative new approaches for studying our changing planet.

These small satellites range in size from a loaf of bread to a small washing machine and weigh from a few to 400 pounds (180 kilograms). Their small size keeps development and launch costs down as they often hitch a ride to space as a “secondary payload” on another mission’s rocket — providing an economical avenue for testing new technologies and conducting science.
