Title:
Annual Fossil-Fuel CO2 Emissions: Mass of Emissions Gridded by One Degree Latitude by One Degree Longitude.
Description:The 2011 version of this database presents a time series recording 1° latitude by 1° longitude CO2 emissions in units of million metric tons of carbon per year from anthropogenic sources for 1751-2008. Detailed geographic information on CO2 emissions can be critical in understanding the pattern of the atmospheric and biospheric response to these emissions.

Global, regional, and national annual estimates for 1751 through 2008 were published earlier (Boden et al. 2011). Those national, annual CO2 emission estimates were based on statistics about fossil-fuel burning, cement manufacturing and gas flaring in oil fields as well as energy production, consumption, and trade data, using the methods of Marland and Rotty (1984). The national annual estimates were combined with gridded 1° data on political units and 1984 human populations to create the new gridded CO2 emission time series. The same population distribution was used for each of the years as proxy for the emission distribution within each country. The implied assumption for that procedure was that per capita energy use and fuel mixes are uniform over a political unit.

The consequence of this first-order procedure is that the spatial changes observed over time are solely due to changes in national energy consumption and nation-based fuel mix. Increases in fossil-fuel CO2 emissions over time are apparent for most areas.

Title:
Hydrologic water vapor cycle.
Description:The proper simulation of the distribution of water vapor in the climate system is essential to the accurate treatment of the hydrological cycle and the planetary radiation budget. These images show the simulated monthly-averaged distribution of the total column water vapor from a high-resolution configuration of the CCSM Community Atmospheric Model. Shown are months of December and January of the Pacific typhoon season. Each second of the animation shows a simulated 24 hour cycle.

Title:
CCSM3 T341 - TMQ (Water Vapor) / Landscan - JAN and JUL Comparison - Himalayan Watershed Study .
Description: During the winter months, a large amount of snow is deposited on the Himalayan slopes forming the largest water resources in northern India. The continuous melting of this snow feeds the north Indian rivers. During winter, heavy snowfall covers 80 to 90 percent of the Himalayan watershed. During the summer season, only 10 percent of the watershed is covered by snow. Current research is concerned with how climate change may affect heavily populated areas that are dependent on this perennial cycle.
The LandScan Dataset comprises a worldwide population database compiled on a 30" X 30" latitude/longitude grid. LandScan has been developed as part of the Oak Ridge National Laboratory (ORNL) Global Population Project for estimating ambient populations at risk.
The proper simulation of the distribution of water vapor in the climate system is essential to the accurate treatment of the hydrological cycle and the planetary radiation budget. These images show the simulated January and July instantaneous distribution of the total column water vapor from a high-resolution configuration of the CCSM Community Atmospheric Model.

Title:
Fusion energy production by alpha particle injection.
Description: Within the tokamak, we see field coils, the vacuum vessel, blanket modules, divertor cassettes, and equipment for heating and diagnostics. Visible is one of the high-energy neutral beam injectors that heat and drive the plasma. The fusion fuel consists of deuterium and tritium, which are isotopes of ordinary hydrogen (shown in red and green in the visualization). To produce fusion reactions, the fuel must be heated to a temperature of about one hundred million degrees - about ten times the temperature of the core of the sun. At such temperatures, the electrons of atoms are stripped from the nuclei forming as a state of matter called plasma. One method of achieving these high temperatures is by injecting beams of high-energy neutral atoms into the tokamak. An initial plasma is formed and heated by driving an electric current through the fuel gas in the tokamak chamber. When the plasma reaches a sufficient density and temperature, the injectors are turned on. Because injected atoms are electrically neutral, they are unaffected by the magnetic field and can penetrate deep into the plasma before being ionized by collisions with plasma particles. These very energetic beam ions are trapped by the magnetic field and circulate throughout the plasma, colliding with the plasma particles and transferring energy to them. As the temperature of the plasma rises, due to the beam heating, fusion reactions between the plasma deuterium and tritium begin to occur.
