Large storms can create these waves, which grow and spread upward hundreds of miles above Earth's surface. The AIRS instrument on NASA's Aqua satellite detected gravity waves in the troposphere and stratosphere 12 hours before a deadly EF5 tornado in Moore, Oklahoma, in 2013. On the instrument's next pass 11 hours later, it detected even stronger waves.We pull up 250 miles to the ionosphere, where the waves can be observed by GPS satellites. Here gravity waves are shown in greens and yellows, like ripples in a pond. The waves and tornado were both produced by a long-lived storm system.Understanding the spread of gravity waves improves global weather forecasting and space weather forecasting.Complete transcript available.This video is also available on our YouTube channel. || GravityWavesBeforeAfterMooreTornado_0740_print.jpg (1024x576) [131.1 KB] || GravityWavesBeforeAfterMooreTornado_0740_searchweb.png (320x180) [102.9 KB] || GravityWavesBeforeAfterMooreTornado_0740_thm.png (80x40) [8.3 KB] || GravityWavesBeforeAfterMooreTornado_0740.tif (1920x1080) [3.2 MB] || GravityWavesMooreOK-SameWordsDifferentOrder.webm (1920x1080) [7.4 MB] || GWfacebook-AIRS-TEC-GOES-4k-audio.mp4 (1920x1080) [76.1 MB] || GravityWavesMooreOK-SameWordsDifferentOrder.mp4 (1920x1080) [117.1 MB] || composite (3849x2160) [0 Item(s)] || GW4k-AIRS-TEC-GOES-4k-audio-youtube.en_US.srt [1.2 KB] || GW4k-AIRS-TEC-GOES-4k-audio-youtube.en_US.vtt [1.2 KB] || GW4k-AIRS-TEC-GOES-4k-audio-youtube.mp4 (3840x2160) [240.0 MB] || GWfacebook-AIRS-TEC-GOES-4k-audio.mp4.hwshow [199 bytes] || ", "hits": 151 }, { "id": 4533, "url": "https://svs.gsfc.nasa.gov/4533/", "result_type": "Visualization", "release_date": "2016-12-15T00:00:00-05:00", "title": "Atmospheric CO2 from AIRS 2002-2016", "description": "This visualization is an update of the global distribution and variation of the concentration of mid-tropospheric carbon dioxide observed by the Atmospheric Infrared Sounder (AIRS) on the NASA Aqua spacecraft.

An Animation of Seasonal Vegetation and its effect on Earth's Global Atmospheric Carbon Dioxide", "description": "In this animation, NASA instruments show the seasonal cycle of vegetation and the concentration of carbon dioxide in the atmosphere. The animation begins on January 1, when the northern hemisphere is in winter and the southern hemisphere is in summer. At this time of year, the bulk of living vegetation, shown in green, hovers around the equator and below it, in the southern hemisphere.As the animation plays forward through mid-April, the concentration of carbon dioxide, shown in orange-yellow, in the middle part of Earth's lowest atmospheric layer, the troposphere, increases and spreads throughout the northern hemisphere, reaching a maximum around May. This blooming effect of carbon dioxide follows the seasonal changes that occur in northern latitude ecosystems, in which deciduous trees lose their leaves, resulting in a net release of carbon dioxide through a process called respiration. Carbon dioxide is also released in early spring as soils begin to warm. Almost 10 percent of atmospheric carbon dioxide passes through soils each year.After April, the northern hemisphere moves into late spring and summer and plants begin to grow, reaching a peak in the late summer. The process of plant photosynthesis removes carbon dioxide from the air. The animation shows how carbon dioxide is scrubbed out of the atmosphere by the large volume of new and growing vegetation. Following the peak in vegetation, the drawdown of atmospheric carbon dioxide due to photosynthesis becomes apparent, particularly over the boreal forests.Note that there is roughly a three-month lag between the state of vegetation at Earth's surface and its effect on carbon dioxide in the middle troposphere.Data like these give scientists a new opportunity to better understand the relationships between carbon dioxide in Earth's middle troposphere and the seasonal cycle of vegetation near the surface.Creating the AnimationThis animation was created with data taken from two NASA spaceborne instruments. The concentration of carbon dioxide data from the Atmospheric Infrared Sounder (AIRS), a weather and climate instrument that flies aboard NASA's Aqua spacecraft, is overlain on measurements of vegetation index from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, also on NASA's Aqua spacecraft, to better understand how photosynthesis and respiration influences the atmospheric carbon dioxide cycle over the globe. The animation runs from January through December and repeats. The AIRS tropospheric carbon dioxide seasonal cycle values were made by averaging AIRS data collected between 2003 and 2010, from which the annual carbon dioxide growth trend of 2 parts per million per year has been removed. For example, the data used for January 1 is actually an average of eight years of AIRS carbon dioxide data taken each year on January 1. The vegetation values were made using data averaged over a four-year period, from 2003 to 2006.Further DetailAIRS uses infrared technology to determine the concentration of atmospheric water vapor and several important trace gases as well as information about temperature and clouds. AIRS orbits Earth from pole-to-pole at an altitude of 438 miles (705 kilometers), measuring Earth's infrared spectrum in 3,278 channels spanning a wavelength range from 3.74 microns to 15.4 microns. Originally designed to improve weather forecasts, AIRS has improved operational five-day weather forecasts more than any other single instrument over the past decade. AIRS has also been found to be sensitive to atmospheric carbon dioxide in the middle troposphere, at an altitude of 5 to 10 kilometers or 3 to 6 miles. AIRS is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., under contract to NASA. JPL is a division of the California Institute of Technology in Pasadena.

Driven by the disparate forces of plants and winds, the seasonal rise and fall of this greenhouse gas cycles in tune with the vegetation scattered across the vast landmasses of the Northern Hemisphere. Levels first start to rise in winter after forests and fields go dormant and plants stop photosynthesizing carbon dioxide from the air. But then they spike in early spring as warmer weather arrives and dead vegetation decays, releasing bursts of stored carbon that's confined to the pole by the polar jet stream's fast-moving winds.

The most important trace gas retrieved by AIRS for the study of anthropogenic effects on climate is carbon dioxide. AIRS CO2 retrievals use an analytical method for the determination of carbon dioxide and other minor gases in the troposphere from AIRS spectra. AIRS has provided the first satellite retrieval of mid-tropospheric CO2 under cloudy conditions, without the use of a priori information from models. AIRS retrievals use cloud-cleared thermal IR radiance spectra in the 15 micron band with an accuracy better than 2 ppm, making it ideal for mapping the distribution and transport of carbon dioxide levels in the free troposphere. || ", "hits": 67 } ] }
