NASA - National Aeronautics and Space AdministrationPasadena, CA – You can’t predict the outcome of a marathon from the runners’ times in the first few miles. You’ve got to see the whole race. Global climate change is like that: You can’t understand it if all you have is a few years of data from a few locations. That’s one reason that a fourth-generation satellite launching this summer is something to get excited about.

Jason-3, a mission led by the National Oceanic and Atmospheric Administration that is currently scheduled to launch on July 22nd, is the latest in a series of U.S.-European satellite missions that have been measuring the height of the ocean surface for 23 years.

NASA reports Researchers looking into United States Methane “Hot Spot”

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers from several institutions are in the Four Corners region of the U.S. Southwest with a suite of airborne and ground-based instruments, aiming to uncover reasons for a mysterious methane “hot spot” detected from space.

“With all the ground-based and airborne resources that the different groups are bringing to the region, we have the unique chance to unequivocally solve the Four Corners mystery,” said Christian Frankenberg, a scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California, who is heading NASA’s part of the effort.

NASA reports NOAA to launch Deep Space Climate Observatory to measure the Sun’s Solar Wind

 

Written by Karen C. Fox
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – There’s a fascinating spot some 932,000 miles away from Earth where the gravity between the sun and Earth is perfectly balanced. This spot captures the attention of orbital engineers because a satellite can orbit this spot, called Lagrange 1 just as they can orbit a planet.

But the spot tantalizes scientists as well: Lagrange 1 lies outside Earth’s magnetic environment, a perfect place to measure the constant stream of particles from the sun, known as the solar wind, as they pass by.

In early February, the United States Air Force will launch a National Oceanic and Atmospheric Administration (NOAA) satellite called Deep Space Climate Observatory, or DSCOVR, into orbit around this spot.

NASA’s Soil Moisture Active Passive (SMAP) observatory could help develop better Weather Forecasts

 

Written by Carol Rasmussen
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – If you were trying to forecast tomorrow’s weather, you would probably look up at the sky rather than down at the ground. But if you live in the U.S. Midwest or someplace with a similar climate, one key to a better weather forecast may lie beneath your feet.

Precipitation and temperature are part of every weather forecast. Precipitation comes from clouds, clouds are formed of airborne water vapor, and vapor comes from evaporating soil moisture — so soil moisture governs precipitation.

NASA's SMAP's soil moisture measurements will help with forecasts of precipitation and temperature. (UCAR)

New NASA Study reveals ozone-depleting compound tetrachloride abundant in Earth’s Ozone Layer

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – High above Earth, more than 20 miles above sea level, a diaphanous layer of ozone surrounds our planet, absorbing energetic UV rays from the sun.

It is, essentially, sunscreen for planet Earth. Without the ozone layer, we would be bathed in dangerous radiation on a daily basis, with side effects ranging from cataracts to cancer.

People were understandably alarmed, then, in the 1980s when scientists noticed that man made chemicals in the atmosphere were destroying this layer.

NASA reports International Space Station to monitor Lake Erie Algae Growth problem

NASA - National Aeronautics and Space AdministrationHouston, TX – The green stuff that clouds up fish tanks – it’s not just an aesthetic annoyance. In fact, if you’ve been watching recent news of algal bloom concerns in Lake Erie, you know that the right conditions for algae can lead to contamination of local water sources, potentially impacting aquatic life and humans.

What you might not have known is that among the resources to help study this problem you will find the International Space Station’s Hyperspectral Imager for the Coastal Ocean (HICO).

NASA’s QuikScat satellite to be used to calibrate it’s successor RapidScat

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – June 19th marked the 15th anniversary of the launch of NASA’s QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners.

On this anniversary, the mission’s team is calibrating ISS-RapidScat, the successor that will maintain QuikScat’s unbroken data record. After its launch in a few months, RapidScat will watch ocean winds from the International Space Station (ISS) for a two-year mission.

Using data from NASA's QuikScat, weather forecasters were able to predict hazardous weather events over oceans 6 to 12 hours earlier than before these data were available. Orange areas show where winds are blowing the hardest and blue shows relatively light winds. (NASA)

NASA’s Jason-2 satellite data points to possible El Niño in 2014

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world’s oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate.

Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like 1997.

NASA researchers and National Snow and Ice Data Center reports Melting Season in Arctic lasting longer

 

Written by Maria-José Viñas
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

Arctic sea ice has been in sharp decline during the last four decades. The sea ice cover is shrinking and thinning, making scientists think an ice-free Arctic Ocean during the summer might be reached this century. The seven lowest September sea ice extents in the satellite record have all occurred in the past seven years.

NASA - National Aeronautics and Space AdministrationMountain View, CA – NASA’s Global Hawk research aircraft returned to its base at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, CA, early Friday morning March 14th, marking the completion of flights in support of this year’s Airborne Tropical Tropopause Experiment (ATTREX), a multi-year NASA airborne science campaign.

On February 13th, the autonomously operated aircraft began conducting science flights from Andersen Air Force Base on Guam in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth’s climate.
