    Faster Weather Tracking On The Way. Feb. 23 Live Shots About Upcoming Launch Of GOES-S

    Feb. 20th, 2018
    (updated May 3rd, 2023)

    B-roll to be added Thursday, Feb. 22nd at 6:00 p.m. ET || Calling All Meteorologists! Faster Weather Tracking On The WayU.S. Will Now Have Two of the Most Advanced Weather Satellites Ever, Operating in Tandem NOAA Scientists Available Feb. 23 to Talk about New GOES-S Satellite Launching Next WeekLast year’s historic hurricanes and wildfires and extreme storm systems called for fast and reliable weather forecasting. On Thursday, March 1, NASA will launch NOAA’s newest weather satellite, GOES-S, which will scan the Earth five times faster and at four times the image resolution. GOES-S is the second of NOAA’s new series of advanced geostationary weather satellites. With it, the United States will now have two of the most advanced weather satellites working in tandem to provide unprecedented coverage across the entire U.S. and most of the Western Hemisphere, from the west coast of Africa to New Zealand. This includes the northeastern Pacific, the birthplace of many weather systems that affect the continental U.S., and where there is comparatively little data.Join NOAA scientists from 6:00 a.m. -12:00 p.m. ET on Friday, Feb. 23 — just days before launch — to learn how GOES-S will help forecasters predict and emergency officials plan for future extreme weather and natural disasters.The new GOES-S satellite has triple the number of channels from older geostationary weather satellites, which allow it to see in different wavelengths of light, including a new near-infrared band, which can discern between snow, ice and clouds. GOES-S will track storm systems, lightning, wildfires, coastal fog and other weather hazards that threaten the U.S. – particularly in the western U.S., Hawaii and Alaska. It will also give forecasters and emergency responders more time to prepare for severe weather across the U.S. as storm systems move east. GOES-S is a joint collaboration between NOAA and NASA.**Schedule a live or taped interview**Michelle Handleman / michelle.z.handleman@nasa.gov / 301-286-0918HD Satellite Coordinates for G17-K24/Lower: Galaxy 17 Ku-band Xp 24 Slot Lower| 91.0 ° W Longitude | DL 12171.0 MHz | Vertical Polarity | QPSK/DVB-S | FEC 3/4 | SR 13.235 Mbps | DR 18.2954 MHz | HD 720p | Format MPEG2 | Chroma Level 4:2:0 | Audio EmbeddedSuggested Questions:1.

    2016 Sea Ice Minimum Live Shots

    Aug. 15th, 2016
    (updated May 3rd, 2023)

    Arctic Sea Ice Live Shot Roll-Ins || Arctic Sea Ice Trending Low After Record 2016 Heat NASA Scientists Available August 19 To Show New Views Of The Arctic During Summer Melt SeasonRecord-breaking temperatures in the first half of 2016 have primed the Arctic for another summer of low sea ice cover. Sea ice is frozen ocean water around the polar caps that, in the winter thickens and grows and in the summer thins and decreases. Arctic sea ice is important because it reflects sunlight and keeps the Arctic region cool. Over the past three decades, Arctic sea ice has dramatically declined; making what was once extraordinary low measurements the new normal. Join NASA scientists on Friday August 19th from 6:00 a.m. – 11:30 a.m. EDT to show your viewers new images from the Arctic, and talk about how the polar region is fairing this summer, and how long-term changes in this region could affect the way we live in the U.S. The Arctic is Earth’s air conditioner and it helps regulate global temperatures. But the region is warming twice as fast as elsewhere in the world, making the Arctic one of the most visible signs of a changing planet. NASA is keeping a close eye on changing conditions in the Arctic with its satellites, airborne and ground campaigns that are measuring the polar sea ice. Scientists are also monitoring the ice sheets that sit on land that are also melting at increasing rates. In 2018 NASA will launch the ICESat-2 satellite that will make some of the most advanced measurements of the polar regions ever. ** To book a window **Michelle Handleman/ michelle.z.handleman@nasa.gov / 301-286-0918 workHD Satellite Coordinates for AMC9-K17/Slot AB (18MHz): AMC-9 Ku-band Xp 17 Slot AB| 83.0 ° W Longitude | DL 12045.0 MHz | Horizontal Polarity | QPSK/DVB-S | FEC 3/4 | SR 13.235 Mbps | DR 18.2954 MHz | HD 720p | Format MPEG2 | Chroma Level 4:2:0 | Audio EmbeddedSuggested Questions:1.Globally it’s been the warmest year on record.

    European Jet Stream

    May 20th, 2014
    (updated Aug. 25th, 2023)

    Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere's polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere. The jet is created by the convergence of cold air masses descending from the Arctic and rising warm air from the tropics. Deep troughs and steep ridges emerge as the denser cold air sinks and deflects warm air regions north, giving the jet stream its wavy appearance. This pattern propagates across the mid-latitudes of North America, Europe and Asia, as pockets of cold air sporadically creep down from the Arctic—creating contrasting waves and flows that accelerate eastward due to Earth's rotation. This visualization uses weather and climate observations from NASA's MERRA data model. ||

    Wild, Wild Winds

    April 3rd, 2014
    (updated May 3rd, 2023)

    Powerful winds whip around Earth, affecting the planet's weather and climate. Such winds make up the Northern Hemisphere’s polar and subtropical jet stream. Undulating in the sky miles above the surface, these rapidly moving air currents flow eastward like rivers in the atmosphere. The polar jet stream travels in the mid-latitudes while the subtropical jet stream passes near the tropics. Sometimes the jets converge or park above a region. In summer 2010, the polar jet stream shifted north and lingered for more than two months over Eurasia. A stationary high-pressure area developed as a result that disrupted the normal movement of weather systems. This contributed to extreme drought in Russia and devastating floods in Pakistan. Watch the video to see a NASA visualization that shows the motions of winds above Europe and Asia during these events. ||

    Arctic Sea Ice Reaches 2019 Minimum Extent

    Sept. 23rd, 2019
    (updated May 3rd, 2023)

    Music: Hiraeth by Anthony Edwin Phillips [PRS], James Edward CollinsComplete transcript available. || Arctic sea ice likely reached its 2019 minimum extent of 1.60 million square miles (4.15 million square kilometers) on Sept. 18, tied for second lowest summertime extent in the satellite record, according to NASA and the National Snow and Ice Data Center.The Arctic sea ice cap is an expanse of frozen seawater floating on top of the Arctic Ocean and neighboring seas. Every year, it expands and thickens during the fall and winter and grows smaller and thinner during the spring and summer. But in the past decades, increasing temperatures have caused marked decreases in the Arctic sea ice extents in all seasons, with particularly rapid reductions in the minimum end-of-summer ice extent. The shrinking of the Arctic sea ice cover can ultimately affect local ecosystems, global weather patterns, and the circulation of the oceans. ||

    Sea Ice Maximum/Operation IceBridge Live Shots

    March 22nd, 2016
    (updated May 3rd, 2023)

    B-roll and canned interviews will be added on Thursday, March 24 || Just three months into 2016 and already global temperatures – particularly in the Arctic – are far warmer than normal. Global temperatures for February were the warmest on record for that month.Nowhere is this warming trend felt more than in theArctic where the unusual wintertime warmth has contributed to record low wintertime sea ice extent. Arctic sea ice keeps the Polar Regions cold and helps regulate global temperatures. The shrinking of sea ice is a key indicator of our planet’s health.NASA is monitoring the health of the Arctic from space and the ground. In the coming days NASA will launch two missions – Operation Ice Bridge and OMG (Oceans Melting Greenland). These airborne and ground campaigns to the Arctic will take measurements of sea ice and glacier thickness.Join NASA scientists on Friday, March 25 from 6:00 a.m. – 11:30 a.m. EDT to see new images of this year’s sea ice extent; talk about how the Arctic faired this winter; and find out the latest on NASA missions to the Arctic set to launch in the coming days.Suggested Questions:1. What do the latest images show us about this year’s winter in the Arctic?2. What do the images tell us about the long-term trend?3. NASA is getting ready to send out teams of scientists to the Arctic in the comingdays. What will they be doing?4.

    NASA On Air: NASA's ARISE Mission Explores Changes In The Arctic (8/22/2014)

    Aug. 22nd, 2014
    (updated May 3rd, 2023)

    LEAD: What has happened to summer? The summer’s temperatures for much of U.S. (except the western U.S. coast) are cooler than normal. This, following the bitter polar vortex chill back in January. What’s going on? 1. One of many driving forces of this weather (besides El Niño, NAO, PDO, etc.) might be the jet stream’s interaction with the Arctic Ocean. 2. The Arctic is warming at twice the rate of the rest of the world, partly because the sea ice is melting, allowing the sun to warm up the ocean water. 3. But more open water means more evaporation and clouds. Will more clouds act as cooling sun umbrellas, or warming blankets in the future? NASA’s new ARISE mission onboard the flying C-130 laboratory will look for some answers this coming September. TAG: The peak of the Arctic sea ice melt usually happens in mid-September. Expect new NASA images then. ||
