NASA instruments keep eye on Hurricane Michael from Space

October 11, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA –  Hurricane Michael plowed into the Florida panhandle Wednesday, October 10th, 2018 as a major Category 4 storm — the strongest hurricane ever to hit that region. Many NASA instruments are keeping tabs on Michael from space, including the Atmospheric Infrared Sounder (AIRS) and the Multi-angle Imaging SpectroRadiometer (MISR).

The first image, taken by AIRS, shows Hurricane Michael just off the west coast of Florida on October 10th in the early morning hours local time. The large purple area indicates very cold clouds at about -90°F (-68°C) carried high into the atmosphere by deep thunderstorms.

This AIRs image shows the temperature of clouds or the surface in and around Hurricane Michael. Purple represents very cold clouds, the much warmer eye is shown in green, and the red areas are warmer and mostly cloud-free. (NASA/JPL-Caltech)

NASA satellite instruments help detect, track Wildfires

January 28, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA – NASA’s satellite instruments are often the first to detect wildfires burning in remote regions, and the locations of new fires are sent directly to land managers worldwide within hours of the satellite overpass.

Together, NASA instruments, including a number built and managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, detect actively burning fires, track the transport of smoke from fires, provide information for fire management, and map the extent of changes to ecosystems, based on the extent and severity of burn scars.

NASA Satellite data used to create maps to predict future Climate Change

Pasadena, 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

February 9, 2016 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, 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 study gives glimpse into Earth’s Future Climate

May 24, 2014 |

Written by Carol Rasmussen
NASA Earth Science News Team

Pasadena, CA – If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models.

In the virtual Earths of the models, interlocking mathematical equations take the place of our planet’s atmosphere, water, land and ice. Supercomputers do the math that keeps these virtual worlds turning — as many as 100 billion calculations for one modeled year in a typical experiment. Groups that project the future of our planet use input from about 30 such climate models, run by governments and organizations worldwide.

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

Pasadena, 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 Aqua spacecraft captures image of Severe Weather in Southern United States

Pasadena, CA – An unusually quiet start to the spring 2014 tornado season in the United States ended abruptly Sunday, April 27th. That’s when severe weather moved through the central and southern states, and it is continuing through Tuesday, April 29th.

The National Weather Service (NWA) says, as of Tuesday morning, more than 110 tornados had been reported, resulting in numerous fatalities across several states.

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

August 28, 2013 |

Pasadena, 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 Aqua spacecraft provides scientists with relative humidity data that could help forecast Hurricane Strengths

Pasadena, 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.

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 study shows Climate change likely hotter than current Projections

November 12, 2012 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – A new NASA-funded study by the National Center for Atmospheric Research, Boulder, CO, finds climate model projections that show a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise.

The findings, published today in the journal Science, could provide a breakthrough in the longstanding quest to narrow the range of global warming expected in coming decades and beyond.

Scientists used observations from two NASA satellite instruments, including relative humidity data similar to these, from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft, to analyze how well leading global climate models reproduce observed relative humidity in Earth’s tropics and subtropics. The AIRS surface relative humidity data shown here are representative only and are not from the study. Areas shown in reds and yellows are the driest; blue areas the moistest.
