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 and NOAA study shows warmer weather increasing Carbon Emissions from Alaska Tundra

 

Written by Ellen Gray
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Warmer temperatures and thawing soils may be driving an increase in emissions of carbon dioxide from Alaskan tundra to the atmosphere, particularly during the early winter, according to a new study supported by NASA and the National Oceanic and Atmospheric Administration (NOAA).

More carbon dioxide released to the atmosphere will accelerate climate warming, which, in turn, could lead to the release of even more carbon dioxide from these soils.

A new paper led by Roisin Commane, an atmospheric researcher at Harvard University in Cambridge, Massachusetts, finds the amount of carbon dioxide emitted from northern tundra areas between October and December each year has increased 70 percent since 1975.

NASA’s Atmospheric Infrared Sounder (AIRS) 3D maps of the atmosphere improve weather forecasts worldwide

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Accurate weather forecasts save lives. NASA’s Atmospheric Infrared Sounder (AIRS) instrument, launched on this date 15 years ago on NASA’s Aqua satellite, significantly increased weather forecasting accuracy within a couple of years by providing extraordinary three-dimensional maps of clouds, air temperature and water vapor throughout the atmosphere’s weather-making layer.

Fifteen years later, AIRS continues to be a valuable asset for forecasters worldwide, sending 7 billion observations streaming into forecasting centers every day.

Besides contributing to better forecasts, AIRS maps greenhouse gases, tracks volcanic emissions and smoke from wildfires, measures noxious compounds like ammonia, and indicates regions that may be heading for a drought. Have you been wondering how the ozone hole over Antarctica is healing? AIRS observes that too.

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

 

Written by Michelle Smith
National Oceanic and Atmospheric Administration

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.

The International Space Station is becoming an increasingly busy platform for studying our home planet. (NASA)

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 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.
