Greenbelt, MD – NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite analyzed the temperatures in Hurricane Nate’s cloud tops and determined that the most powerful thunderstorms and heaviest rain areas were around the center of the tropical cyclone after it made landfall near the mouth of the Mississippi River.

At 8:00pm EDT/7:00pm CDT on October 7th, 2017 Hurricane Nate’s eye was at the mouth of the Mississippi River. National Weather Service radar data and surface observations indicated that Hurricane Nate made landfall near Biloxi, Mississippi, around 12:30am CDT/1:30am EDT on October 8th, with maximum winds of 85 mph (140 kph).

On October 8th at 4:20am EDT (0820 UTC) the MODIS instrument aboard NASA’s Aqua satellite analyzed Nate’s cloud top temperatures in infrared light and found strongest storms (yellow) around the center of circulation. (NASA/NRL)

Greenbelt, MD – NASA-NOAA’s Suomi NPP satellite captured night-time look at Hurricane Irma as it weakened to a large tropical storm and the GOES East satellite provided a daytime view as the large storm continued moving north over Florida.

Irma made landfall twice on September 10th, 2017, first in the Florida Keys and then near Naples. The storm has now been downgraded to a tropical storm but could still cause significant impacts over Georgia and Alabama. NASA’s Marshall Space Flight Center in Huntsville, Alabama was under a Tropical Storm Watch on September 11th.

NASA-NOAA’s Suomi NPP satellite captured this night-time infrared image of Hurricane Imra on Sept. 11, 2017 at 3:21 a.m. EDT (0721 UTC) located over central Florida. (NOAA/NASA Goddard Rapid Response Team)

NASA and NOAA Satellites capture images of Hurricane Irma hitting Florida

Greenbelt, MD – As Hurricane Irma approached southern Florida, a NASA satellite captured a night-time image of the storm in the Florida Straits and identified where the strongest storms were occurring within Irma’s structure. NOAA’s GOES satellite provided a visible image at the time of Irma’s landfall in the Florida Keys.

As Irma moved along the coast of Cuba, the storm weakened to a Category 3 Hurricane on the Saffir-Simpson Hurricane Wind Scale.

After moving away from the northern coast of Cuba, Irma passed over waters that are warmer than 30 degrees Celsius (86 degrees Fahrenheit).

This visible image of Category 4 Hurricane Irma was taken on Sunday Sept. 10, 2017 at 9:25 a.m. EDT (1325 UTC) by the NOAA GOES East satellite as its eye approached the southwestern coast of Florida. Hurricane Jose is seen (right) near the Leeward Islands. (NASA/NOAA GOES Project)

Greenbelt, MD – Satellite imagery from NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite have provided different data on the still Category 5 Hurricane Irma as it headed for the Turks and Caicos Islands.

On September 6th at 1:45pm EDT (1745 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite captured a visible-light image of Hurricane Irma over the Leeward Islands and Puerto Rico. The image revealed a clear eye with powerful bands of thunderstorms circling the eye.

Greenbelt, MD – NASA and NOAA satellites have been providing valuable satellite imagery to forecasters at the National Hurricane Center, and revealed that Hurricane Irma has strengthened to a Category 5 hurricane on September 5th, 2017 around 8:00am EDT (1200 UTC).

On September 4th at (1:24pm EDT) 17:24 UTC, NASA-NOAA’s Suomi NPP satellite captured this view of Hurricane Irma as a Category 4 hurricane approaching the Leeward Islands. The VIIRS instrument on the Suomi NPP satellite flew over Hurricane Irma on September 4th at 04:32 UTC (12:32am EDT) when it was a Category 3 hurricane.

The VIIRS instrument on the Suomi NPP satellite flew over Category 3 Hurricane Irma at approximately on Sept. 4 at 04:32 UTC (12:32 a.m. EDT). Cloud top temperatures were near -117.7F/-83.5C in the western quadrant. (UWM/SSEC/CIMSS, William Straka III)

Greenbelt, MD – NASA-NOAA’s Suomi NPP Satellite provided a night-time and infrared look at the Atlantic’s latest hurricane that revealed the power under the clouds. NASA’s GPM also provided a look at the rainfall being generated by Hurricane Irma.

After forming in the eastern Atlantic Ocean on Wednesday tropical storm Irma strengthened and became a powerful category three hurricane on Thursday August 31st, 2017.

On Sept. 1st at 0347 UTC (Aug. 31 at 11:47 p.m. EDT) the VIIRS instrument aboard NASA-NOAA’s Suomi NPP satellite captured a night-time image of Hurricane Irma in the Atlantic Ocean that showed a tight circulation. (NASA/NOAA/UWM-CIMSS, William Straka III)

NASA tracks dust plume from Chelyabinsk Meteor explosion through the Stratosphere

August 18, 2013 |

Washington, D.C. – Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia.

From Greenbelt, MD, however, NASA’s Gorkavyi and colleagues witnessed the atmospheric aftermath. The explosion created a never-before-seen belt of “meteor dust” that circulated through the stratosphere for at least three months.

NASA-NOAA Suomi National Polar-orbiting satellite captures intriguing images of the Earth at Night

December 7, 2012 |

Washington, D.C. – At the American Geophysical Union meeting in San Francisco, scientists unveiled an unprecedented new look at our planet at night.

A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across Earth in greater detail than ever before.

This image of the continental United States at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The image was made possible by the satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires and reflected moonlight.
