Washington, Oct 24 : A new research has indicated that a powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated.
The research, based on data from a NASA-funded measurement network, examined nitrogen trifluoride, which is thousands of times more effective at warming the atmosphere than an equal mass of carbon dioxide.
Using new analytical techniques, Ray Weiss of the Scripps Institution of Oceanography in La Jolla, California, led a team of researchers in making the first atmospheric measurements of nitrogen trifluoride.
The amount of the gas in the atmosphere, which could not be detected using previous techniques, had been estimated at less than 1,200 metric tons in 2006.
