New video released by scientists at NASA Goddard's Global Modeling and Assimilation Office reveals how the greenhouse gas carbon dioxide in the atmosphere travels around the globe in a single year. The results focus on a period between May 2005 and June 2007. At the
New study from Boston University, the University of Michigan and other institutions identifies a new, direct fingerprint of human activity on Earth as agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere.Modern agricultural
NASA Goddard Space Flight Center scientist Andrew Sayer talks about how emissions from volcanoes can affect clouds. This video provides an overview of research published in the Journal of Atmospheric Chemistry and Physics. Research: Systematic satellite observations of
A rare fallstreak hole cloud was observed today over Melbourne, Australia, Meteo Europe team reports. Because of their rarity and unusual appearance, as well as very little exposure in media, fallstreak holes are often mistaken for or attributed to unidentified flying o
According to scientists from NASA and NOAA, the Antarctic ozone hole reached its annual peak on September 11 with the size of 24.1 million square kilometers (93 million square miles). Overall, the 2014 ozone hole is smaller than the large holes of the 1998–2006 pe
A new system, called the “Fossil Fuel Data Assimilation System,” (FFDAS) has been used to quantify 15 years of CO2 emissions, every hour, for the entire planet – down to the city scale.An international research team led by ASU scientists has developed
September 16, 2014 – The World Ozone Day, is meant to commemorate the success that has been achieved in ameliorating ozone depletion since the enactment of the Montreal Protocol, but also to bring attention to the work ahead. In their first review in four years on
Earth has split open between the Bardarbunga and Askja volcanoes in Iceland and spewed lava and hot gas. According to the University of Iceland, as of September 9, 2014, the new lava flow was 16 kilometers (10 miles) long and covered about 20 square kilometers (8
New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound – Carbon tetrachloride (CCl4) – from an unknown source decades after the compound was banned worldwide.Carbon tetrachloride was regulated
Research meteorologists at the U.S. Naval Research Laboratory (NRL) Marine Meteorology Division (MMD) and Scripps Institution of Oceanography, employing the Navy's Mid-Course Doppler Radar (MCR) at Cape Canaveral, were able to characterize mid-level, mixed-phase alt
