            "description": "This visualization is a time-series 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. For comparison, it is overlain by a graph of the seasonal variation and interannual increase of carbon dioxide observed at the Mauna Loa, Hawaii observatory.The graph shows data, commonly called the Keeling Curve, from the Scripps measurements of monthly carbon dioxide concentration at Mauna Loa Observatory. The collection of this data was started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976]. The two most notable features of this visualization are the seasonal variation of carbon dioxide and the trend of increase in its concentration from year to year.

The Northern Hemisphere has the majority of the land masses, and so the amplitude of the cycle is greater in that hemisphere. The overall color of the map shifts toward the red with advancing time due to the annual increase of carbon dioxide.The concentration of carbon dioxide in the mid-troposphere lags the concentration found at the surface as mixing from the lower to upper altitudes usually takes days to weeks.More information about AIRS can be found at http://airs.jpl.nasa.gov.

            "title": "Watching the Earth Breathe: <br>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.

            "description": "The air above the icy and remote Arctic experiences larger carbon dioxide fluctuations than anywhere on the planet. 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 visualization uses data from the Atmospheric Infrared Sounder on NASA's Aqua satellite to show the changing carbon dioxide levels above the Arctic from February 2010 to February 2011. || ",

            "title": "Discovering A Belt Of Carbon Dioxide",
            "description": "When scientists got their first glimpse of satellite data showing the distribution of carbon dioxide throughout the atmosphere, they in part saw what they expected: an uneven distribution of the greenhouse gas over the globe, with higher levels in the more populated, more industrial Northern Hemisphere. But they also saw a dominant feature that was wholly unexpected. A continuous belt of higher carbon dioxide concentrations circled an area in the Southern Hemisphere that covered the tip of South America, Africa and southern Australia. Computer models that predict how chemicals move throughout the atmosphere did not predict this band. Scientists now think that strong thunderstorms and winds that flow around South America's high Andes Mountains lift carbon dioxide into what's called the \"free troposphere.\" There it becomes trapped in the jet stream of the mid-latitudes, which propel it around the world. The sources of this belt are many: industry and power plants in coal-rich South Africa, electricity generation in eastern Australia and in Buenos Aires, Argentina, as well as plant respiration and fires. Watch the visualization below to see the first evidence of the belt, as detected by the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite in 2003. AIRS now provides scientists with unprecedented global data on greenhouse gases in the atmosphere. || ",

            "description": "The slash-and-burn practices farmers use in parts of South America to clear land before planting in the spring added to a severe Amazon fire season in 2005. Dramatic increases in carbon monoxide were recorded over South America in August, September, and October of that year. But a satellite instrument also saw the fire emissions travel far beyond the continent. Plumes of the colorless, odorless gas, which can linger in the atmosphere up to three months, moved across the Atlantic Ocean and likely affected the air quality over Africa. Scientists measured this carbon monoxide path using an instrument called AIRS onboard NASA's Aqua satellite. AIRS was designed to measure water vapor, clouds, and air and land temperatures. Once it was launched, scientists realized they could use it to make global carbon monoxide and carbon dioxide measurements, providing unprecedented global views of greenhouse gas distributions in the atmosphere. Watch in the visualization below how AIRS saw carbon monoxide fire emissions sweep out over the Atlantic Ocean, above Africa, toward the Indian Ocean and all the way to Australia. || ",

            "description": "AIRS' global carbon monoxide measurements are important because scientists can monitor the transport of fire emissions around the globe on a daily basis. Previously, carbon monoxide measurements came from satellite instruments that saw only part of the Earth each day or from weather balloons. Prior to AIRS, scientists had to integrate those observations with computer models to infer the day-to-day impact of fire emissions on the atmosphere. AIRS provides daily, global coverage. AIRS also measures some of the key atmospheric gases that affect climate, including ozone, methane, and dust and other aerosols.Tropospheric CO abundances are retrieved from the 4.67 m region of AIRS spectra as one of the last steps of the AIRS team algorithm. AIRS' 1600 km cross-track swath and cloud-clearing retrieval capabilities provide daily global CO maps over approximately 70% of the Earth. The streak of red, orange, and yellow across South America, Africa, and the Atlantic Ocean in this animation points to high levels of carbon monoxide, as measured by the Atmospheric Infrared Sounder (AIRS) instrument flying on NASA's Aqua satellite. The carbon monoxide primarily comes from fires burning in the Amazon basin, with some additional contribution from fires in southern Africa. The animation shows carbon monoxide transport sweeping east throughout August, September, and October 2005. || ",

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. || ",

            "description": "A NASA/university study of the first-ever global satellite maps of carbon dioxide in Earth's atmosphere has revealed new information on how this key greenhouse gas linked to climate change is distributed and moves around our world. Moustafa Chahine, lead study author and AIRS science team leader at NASA's Jet Propulsion Laboratory, Pasadena, Calif., said the maps, which cover from September 2002 to July 2008, will be used by scientists to refine how climate models represent the processes that transport carbon dioxide within Earth's atmosphere. 'These data capture global variations in the distribution of carbon dioxide over time that are not represented in the existing models used to determine where carbon dioxide is created and stored,' he said. Chahine said the previous scientific consensus was that carbon dioxide was evenly mixed in the free troposphere, decreasing as you move farther south of the equator. 'Our results show carbon dioxide there can vary by nearly one percent and that the free troposphere is like international waters-what's produced in one place is free to travel elsewhere,' he said.This visualization is a time-series 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.

In the southern hemisphere, a belt of mid-tropospheric air containing enhanced concentrations of carbon dioxide emerged between 30 and 40 degrees south latitude. This belt had not previously been seen in any chemistry transport model. Subtropical storms track through this region, as do the cloud bands of the intertropical convergence zone near the equator, an area of low atmospheric pressure that forms where northeast and southeast trade winds meet.The researchers believe strong convection (thunderstorms) in this belt, and South America's high Andes Mountains, lift carbon dioxide from major sources on Earth's surface, such as the respiration of plants, forest fires and facilities for producing synthetic fuels and generating power. This carbon dioxide is then carried into the 'free troposphere,' the part of the troposphere that is too high to be influenced by Earth's surface. There, it becomes trapped in the mid-latitude jet stream, which transports it rapidly around the world. For more information on AIRS, visit the AIRS Project Web Site: http://airs.jpl.nasa.gov.

Forest fires create large amounts of carbon monoxide. AIRS provides daily global maps of carbon monoxide from space, allowing scientists to follow the global transport of this gas day-to-day. This visualization shows the amount of Carbon monoxide that has risen 2 to 8 kilometers (6,500 ft to 26,200 ft altitude) from August 24-28, 2007.  More carbon monoxide generally means more pollution, either natural from wildfires or from industrial and domestic sources.Beginning August 24, a significant plume emanates from the extensive fires burning in Greece. This plume moves southeast across the Mediterranean Sea and over North Africa from August 24 to 28. It crosses to Africa and arcs westward over the Sahara Desert and continues to curl around over the Eastern Mediterranean toward Sardinia and Corsica. || ",

            "description": "This visualization shows 3D volumetric water vapor data from the Aqua/Atmospheric Infrared Sounder (AIRS) instrument. As the camera moved down and around the data set, the low data values are faded out revealing only the highest concentrations of water vapor data. The color and opacity at each 3D voxel are driven by the water vapor data. The data set was obtained by Aqua on January 1, 2003. Only data from the sea level to about 10 km are shown.This visualization was created to support a JPL press release about how assimilated AIRS data is improving global atmospheric simulation model forecasts by about 6 hours (from about 5 days to about 5 days and 6 hours). || ",
