Chicago: Ice crystals plucked from clouds and quickly analyzed in flight show bits of biological material

Bangalore: Megha-Tropiques, a satellite to study tropical weather and climate, is in an advanced stage of development and likely to be launched in December, according to C.B.S. Dutt, programme coordinator of the mission at the Indian Space Research Organisation (ISRO).

RAJENDRA K Pachauri will lead the newly-established Yale Climate and Energy Institute (YCEI), which will support research and outreach, international collaboration, partnerships with business and industry, and green design efforts that can be implemented and tested within Yale and the surrounding region, Yale University president Richard C Levin has announced.

Houston, March 2

US Indian scientist, Veerbhadran (Ram) Ramanathan, will share top award for environmental achievement, 2009 Tyler Prize for Environmental Achievement, with Prof Richard Alley, for finding warning signs of climate change in the upper atmosphere and in the deepest ice sheets.

Compound used in manufacture of flat panel televisions, computer displays, microcircuits, solar panels is 17,000 times more potent greenhouse gas than carbon dioxide

A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.

When an equal amount of sulphate (deposited by acid rain) was added, it reduced methane emission by 43 per cent.

JPL Historian Erik Conway provides an overview of the sequence of events that lead to the link between human activity, carbon dioxide, and global warming. Conway also examines how the spaceborne instrument, the Atmospheric Infrared Sounder, has become part of the story.

A NASA/university team has published the first global satellite maps of the key greenhouse gas carbon dioxide in Earth's mid-troposphere, an area about 8 kilometers, or 5 miles, above Earth. The team's study reveals new information on how carbon dioxide, which directly contributes to climate change, is distributed in Earth's atmosphere and moves around our world.

This brochure describes the Atmospheric Infrared Sounder.
AIRS enhances the quality of global meteorological observations which yields considerable economic benefits through more reliable climate prediction, improved weather forecasts, better understanding of the factors influencing air quality, and mitigation of the economic and human costs of natural hazards.
