In a first-of-its-kind study of the bioaerosol composition of the Southern Ocean, researchers from Colorado State University identified an atmospheric region which remains unchanged by human activity.

The Earth Sciences department at the Barcelona Supercomputing Center aims to “develop and implement global and regional models and data solutions for air quality and climate forecasting and their ...

Oxygen isotope composition of tropospheric air. The mean composition of air oxygen from our study (series B; Supplementary Table 1) is δ 18 O=24.15±0.05‰ with Δ' 17 O=−0.469±0.007‰. An ...

Astronomers have characterized the atmosphere of a young (20 Myr old) transiting exoplanet and found it to be unusually clear and puffy. By analyzing the planet's atmospheric features, they were able ...

Unseen in the air around us are tiny molecules that drive the chemical cocktail of our atmosphere. As plants, animals, volcanoes, wildfires and human activities spew particles into the atmosphere ...

Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions. Rising 2,225 meters into the air ...

On behalf of the National Oceanic and Atmospheric Administration (NOAA), NASA has selected two firms for the the Geostationary Extended Observations (GeoXO) Atmospheric Composition (ACX) Phase A St… ...
