Weary travelers were stranded at airports as air traffic across the Atlantic and over parts of Europe came to a halt. A European geostationary satellite, which orbits Earth above a single point, tracked the movement of the ash clouds as westerly winds carried them high above the ocean and toward northern Europe. Meanwhile, NASA's CALIPSO satellite measured the height and thickness of the material ejected into the atmosphere using its lidar instrument and infrared sensors. Together, the satellites created an unprecedented view of the eruption's aftermath. Watch the visualization below to see the movement and 3-D structure of the ash clouds released by Eyjafjallajokull volcano from May 6-8, 2010. || ", "hits": 47 }, { "id": 3783, "url": "https://svs.gsfc.nasa.gov/3783/", "result_type": "Visualization", "release_date": "2010-10-21T00:00:00-04:00", "title": "Iceland's Eyjafjallajökull Volcanic Ash Plume May 6-8, 2010 - Stereoscopic Version", "description": "During April and May, 2010, the Eyjafjallajökull volcano on Iceland's southern coast erupted, creating an expansive ash cloud that disrupted air traffic throughout Europe and across the Atlantic. This animation shows the flow of this ash cloud for three days in early May on an hourly basis as sensed from a geostationary satellite. The ash cloud heights were determined using an approach developed by NOAA/NESDIS/STAR for the next generation of Geostationary Operational Environmental Satellite (GOES-R). Data from EUMETSAT's Spinning Enhanced Visible and Infrared Imager (SEVIRI) was used as a proxy for GOES-R Advanced Baseline Imager (ABI) data. This data is shown intersecting with the CALIPSO Parallel Attenuated Backscatter curtain on May 6th. In this page the visualization content is offered in two different modes to accommodate stereoscopic systems as: Left and Right Eye separate and Left and Right Eye side-by-side combined on the same frame. || ", "hits": 78 }, { "id": 3437, "url": "https://svs.gsfc.nasa.gov/3437/", "result_type": "Visualization", "release_date": "2007-07-22T00:00:00-04:00", "title": "The A-Train Observes Tropical Storm Debby", "description": "The A-Train is a group of spacecraft flying in close formation allowing data taken by each instrument to be correlated to the other instruments providing data synergy. The A-Train includes Aqua, CloudSat, CALIPSO, Parasol, and Aura. The animation begins showing the Earth with moving clouds and with a day/night terminator. Time slows down, and A-train spacecraft orbits are added during a daytime pass. The orbits progress around the globe for 12 hours. During a night time pass the camera zooms into Tropical Storm Debby as the A-train flies over on August 24, 2006. Data sets from some of the A-train's spacecraft/instruments are shown including Aqua/MODIS, CloudSat, CALIPSO, and Aqua/AIRS. This visualization was created to support an A-Train session at the 2007 International Geoscience and Remote Sensing Symposium (IGARSS). || ", "hits": 55 }, { "id": 3365, "url": "https://svs.gsfc.nasa.gov/3365/", "result_type": "Visualization", "release_date": "2006-08-03T00:00:00-04:00", "title": "CALIPSO Profile over China", "description": "Aerosols, small particles in the atmosphere, can be produced from natural sources, such as volcanos and dust storms, or from human activity, such as pollution from manufacturing and automobiles. Aerosols remain in the atmosphere for long periods and travel across the globe propelled by winds.

The CALIOP lidar onboard the CALIPSO satellite enables scientists to collect aerosol data on slices or 'curtains' through the atmosphere. In these images looking eastward across China over the Yellow Sea and the Korean Peninsula, slices of total attenuated backscatter show the geographic location and altitude of both aerosols and subvisible clouds in the upper troposphere.
