Satellite infrared imaging has a very high spatial resolution—one pixel equals approximately one square kilometer—but it can’t see through the clouds. Microwave imaging can see through clouds, but the resolution is much lower, about 25 square kilometers per pixel; the result is something akin...
Typhoon Pabuk's eye was clear on visible and infrared NASA satellite imagery on Sept. 24, and one day later high clouds covered the center and Pabuk's eye was "closed." Satellite data also showed that Pabuk's eye shrunk by about 5 nautical miles in the last day. When NASA's Aqua sat...
The Joint Typhoon Warning Center noted that "animated enhanced infrared satellite imagery shows deepening or strengthening convection (rising air that forms the thunderstorms that make up a tropical cyclone) with colder cloud tops." Colder cloud tops mean that the uplift of air has strengthened and ...
Imagery by the James Webb Space Telescope's NIRCam (Near-Infrared Camera) instrument reveals that Earendel, the most distant known star in the universe.(Image credit: Image: NASA, ESA, CSA, D. Coe (STScI/AURA for ESA; Johns Hopkins University), B. Welch (NASA’s Goddard Spaceflight Cent...
a NASA satellite that uses thermal infrared sensors to help scientists better distinguish flora, fauna, water, and manmade objects. For almost 50 years, NASA has been using satellite imagery to understand how climate change and population growth are affecting our fragile planet. These satellites hel...
"We attribute large-scale thermal unrest to the enhancement of underground hydrothermal activity, and suggest that such analysis of satellite-based infrared observations can improve constraints on the thermal budget of volcanoes, early detection of pre-eruptive conditions and assessments of volcanic alert...
Tropical Cyclone Marcus continues to strengthen as it moves further away from Western Australia. NASA's Aqua satellite analyzed the system in infrared light to find the strongest part of the hurricane. By analyzing a storm in Infrared light, scientists can tell cloud top temperatures that give clu...
The real-time data ingest at the Melbourne Forecast Office consists of background fields from the Rapid Update Cycle model, GOES-8 visible and infrared satellite imagery, Melbourne Weather Surveillance Radar - 1988 Doppler (WSR-88D) radial velocity and reflectivity fields, standard surface reports, ...
Infrared imagery provides scientists with a look at cloud top temperatures intropical cyclones, and the colder the clouds, the higher up in the atmosphere and stronger the storms tend to be. Infrared satellite data of Wutip was captured at 10:25 a.m. EDT (1525 UTC) on Feb. 21 from the ...
From 4 a.m. EDT (0800 UTC) on, animated infrared satellite imagery revealed significant structural improvement with a band of convection nearly encircling the broad low level circulation center. By 11 a.m. EDT (1500 UTC) Saola's maximum sustained winds were near 55 knots (63.2 mph/102 kph...
