Sentence examples for the current atmospheric from inspiring English sources

By some calculations, the tar sands contain the equivalent of about 200 parts per million CO2 – or roughly half the current atmospheric concentration.
The current atmospheric models provide highly accurate forecasts for up to 10 days, says Antonio Busalacchi, president of the University Corporation for Atmospheric Research, a consortium of more than 100 colleges and universities in North America.

Pots of the grass were isolated in chambers where greenhouse gas concentrations were set at either 400 parts per million (roughly the current atmospheric level) or 800 parts per million, and ozone levels were similarly varied between a high and low scenario.
Although plants grown in high levels of carbon dioxide--say, double the current atmospheric concentrations--initially grow rapidly, the growth tapers off within weeks and the plants wind up with a low protein content.
However, radar data has to be complemented by a knowledge of current atmospheric conditions which can allow one to determine if the current atmosphere is conducive to hail development.
Cyanobacteria are capable of converting carbon dioxide into oxygen via photosynthesis and have been proposed as significant players in the evolution of current atmospheric oxygen levels during the Precambrian era (Meeks et al. 2001; Schirrmeister et al. 2013) and as origin of chloroplasts via endosymbiosis with eukaryotic cells (Agapakis et al. 2011; Chu et al. 2004).
These results indicate potential importance of the aerosol feedback effects and an urgent need to further improve the representations in current atmospheric models to reduce uncertainties at all scales.
