NASA - National Aeronautics and Space AdministrationPasadena, CA – The “atmospheric river” weather patterns that pummeled California with storms from late December to late January may have recouped 37 percent of the state’s five-year snow-water deficit, according to new University of Colorado Boulder-led research using NASA satellite data.

Researchers at the university’s Center for Water Earth Science and Technology (CWEST) estimate that two powerful recent storms deposited roughly 17.5-million acre feet (21.6 cubic kilometers) of water on California’s Sierra Nevada range in January.

January storms in the Sierra Nevadas reduced California's deficit in stored snow water by about 37 percent. (Perfect Zero, CC BY 2.0)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New, detailed maps of the world’s natural landscapes created using NASA satellite data could help scientists better predict the impacts of future climate change.

The maps of forests, grasslands and other productive ecosystems provide the most complete picture yet of how carbon from the atmosphere is reused and recycled by Earth’s natural ecosystems.

Scientists at the University of Edinburgh, Scotland, United Kingdom; NASA’s Jet Propulsion Laboratory, Pasadena, California; and Wageningen University, Netherlands, used a computer model to analyze a decade of satellite and field study data from 2001 to 2010.

NASA Study reveals Natural Cycles are not enough to explain Global Warming

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and Duke University in Durham, North Carolina, shows, in detail, the reason why global temperatures remain stable in the long run unless they are pushed by outside forces, such as increased greenhouse gases due to human impacts.

Lead author Patrick Brown, a doctoral student at Duke’s Nicholas School of the Environment, and his JPL colleagues combined global climate models with satellite measurements of changes in the energy approaching and leaving Earth at the top of the atmosphere over the past 15 years.

NASA’s Orbiting Carbon Observatory-2 to study how gardens grow

 

Written by Laurie J. Schmidt
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Science is full of serendipity — moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake.

Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that sheds new light on the productivity of vegetation on land.

NASA’s Terra spacecraft captures overhead view of 2014 Winter Olympic Games sites

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – It’s not often that the Winter Olympic Games come with an ocean view, but that’s what we are getting this year at the Black Sea resort of Sochi, Russia. Sochi is the warmest city ever to host the winter games, which officially run from February 7th through February 23rd.

Two images of the Sochi Olympic venues were acquired on January 4th, 2014, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA’s Terra spacecraft.

NASA’s Aqua and Terra Spacecraft take images of California Rim Fire endangering Yosemite National Park

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Rim Fire burning in and near Yosemite National Park in California continues to grow and move its way up in the record books. As of August 27th, CAL FIRE (California Department of Forestry and Fire Protection) reports that the fire, which started August 17th, had consumed nearly 180,000 acres, making it the seventh largest wildfire in California’s recorded history.

The fire is one of 10 active major wildfires burning across California as of August 27th.

Visible image of California's Rim Fire acquired Aug. 23rd, 2013 by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra spacecraft, showing extensive, brownish smoke. The imaged area measures 236 by 215 miles (380 by 346 kilometers). (Image credit: NASA/GSFC/LaRC/JPL, MISR Team)

NASA’s Terra Spacecraft Photo shows Destructive path of Oklahoma Tornado

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new image taken by NASA’s Terra spacecraft using the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument it has on board reveals the extent of destruction from the deadly Newcastle-Moore tornado that ripped through central Oklahoma on May 20th, 2013.

The Newcastle-Moore tornado was rated at EF-5 on the Enhanced Fujita scale. An EF-5 is the most powerful category of tornado.

The Newcastle-Moore EF-5 tornado ripped through central Oklahoma on May 20, 2013, killing 24 people and leaving behind more than $2 billion in damage. (Image Credit: NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team)

NASA’s Aqua spacecraft provides scientists with relative humidity data that could help forecast Hurricane Strengths

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Forecasters could soon be better able to predict how intense tropical cyclones like Hurricane Sandy will be by analyzing relative-humidity levels within their large-scale environments, finds a new NASA-led study.

Scientists from NASA’s Jet Propulsion Laboratory, Pasadena, CA, UCLA and the University of Hawaii at Manoa analyzed relative humidity data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft for nearly 200 North Atlantic hurricanes between 2002 and 2010.

Hurricane Sandy as seen by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra spacecraft on Oct. 28th, 2012, when the Category 1 storm was centered off the southeastern U.S. coast. A new NASA-led study finds that analysis of relative humidity levels in the large-scale environment of tropical cyclones may be useful in improving forecasts of their intensity.

NASA Satellite Finds Earth’s Clouds are Getting Lower

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Earth’s clouds got a little lower — about one percent on average — during the first decade of this century, finds a new NASA-funded university study based on NASA satellite data. The results have potential implications for future global climate.

Scientists at the University of Auckland in New Zealand analyzed the first 10 years of global cloud-top height measurements (from March 2000 to February 2010) from the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA’s Terra spacecraft.

This image of clouds over the southern Indian Ocean was acquired on July 23, 2007 by one of the backward (northward)-viewing cameras of the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's polar-orbiting Terra spacecraft. (Image credit: NASA/JPL-Caltech)

NASA, Japan Release Improved Topographic Map of Earth

 

Written by Alan Buis
Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA and Japan released a significantly improved version of the most complete digital topographic map of Earth on Monday, produced with detailed measurements from NASA’s Terra spacecraft.

The map, known as a global digital elevation model, was created from images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument aboard Terra. So-called stereo-pair images are produced by merging two slightly offset two-dimensional images to create the three-dimensional effect of depth. The first version of the map was released by NASA and Japan’s Ministry of Economy, Trade and Industry (METI) in June 2009.

At 14,505 feet (4,421 meters) in elevation, California's Mt. Whitney, located in the Sierra Nevada Mountains on the west side of Owens Valley, is the highest point in the contiguous United States. (Image credit: NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team)
