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 observes Tropical Storm Irma moving North up Florida PeninsulaWritten by Rob Gutro
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.

NASA and NOAA Satellites capture images of Hurricane Irma hitting FloridaWritten by Rob Gutro
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) «Read the rest of this article» Sections: Technology | No Comments
NASA uses Satellites to gain different perspective on Hurricane IrmaWritten by Rob Gutro
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. ![]() On Sept. 6 at 1:45 p.m. 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.

NASA and NOAA Satellites observe Hurricane Irma strengthen to Category 5Written by Rob Gutro
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) «Read the rest of this article» Sections: Technology | No Comments
NASA, NOAA’s Suomi NPP Satellite Gives night time look at Hurricane IrmaWritten by Rob Gutro / Hal Pierce
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 tracks dust plume from Chelyabinsk Meteor explosion through the Stratosphere
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. «Read the rest of this article» Sections: Technology | No Comments
NASA-NOAA Suomi National Polar-orbiting satellite captures intriguing images of the Earth at NightWritten by Dr. Tony Phillips
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.
