Geophysical Research Letters is a semi-monthly peer reviewed scientific journal published by the American Geophysical Union that was established in 1974. The editor-in-chief is Eric Calais (Purdue University). The stated purpose of Geophysical Research Letters is rapid publication of conscise research reports that may significantly influence one or more American Geophysical Union disciplines. These particular geoscience disciplines are atmospheric sciences, solid earth, space sciences, ocean sciences, hydrology, land surface processes, and the cryosphere. GRL also publishes twelve invited reviews that cover advances achieved during the past two or three years. The target readership is the earth science community, the broader scientific community, and the general public. This journal is indexed in the following databases: According to the Journal Citation Reports, the journal has a 2010 impact factor of 3.505, ranking it 12th out of 165 journals in the category "Geosciences, Multidisciplinary". Geophysical Research Letters was also the 5th most cited publication on climate change between 1999 and 2009.
Magnetic complexity begins to untangle
After a year in orbit, the three Swarm satellites have provided a first glimpse inside Earth and started to shed new light on the dynamics of the upper atmosphere – all the way from the ionosphere about ...
Study suggests active volcanism on Venus
An international team of scientists has found some of the best evidence yet that Venus, Earth's nearest neighbor, is volcanically active.
Titan's atmosphere even more Earth-like than previously thought
Scientists at UCL have observed how a widespread polar wind is driving gas from the atmosphere of Saturn's moon Titan. The team analysed data gathered over seven years by the international Cassini probe, ...
Alaska glaciers make large contributions to global sea level rise
Alaska's melting glaciers are adding enough water to the Earth's oceans to cover the state of Alaska with a 1-foot thick layer of water every seven years, a new study shows.
Greenhouse gas-caused warming felt in just months
The heat generated by burning a fossil fuel is surpassed within a few months by the warming caused by the release of its carbon dioxide into the atmosphere, according to new work from Carnegie's Xiaochun ...
Astronomers make real-time, 3-D movies of plasma tubes drifting overhead
By creatively using a radio telescope to see in 3D, astronomers have detected the existence of tubular plasma structures in the inner layers of the magnetosphere surrounding the Earth.
Heat accelerates dry in California drought
Although record low precipitation has been the main driver of one of the worst droughts in California history, abnormally high temperatures have also played an important role in amplifying its adverse ef ...
Volcanic ash proves inefficient cloud ice maker
When tons of ash spewed into the atmosphere from a 2010 Icelandic volcano it caused havoc for vacationers across Europe. But did it also dramatically change clouds? Researchers at Pacific Northwest National ...
Evolution of the Antarctic ice sheet
ULB study sheds a new light on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between ...
Deciphering clues to prehistoric climate changes locked in cave deposits
When the conversation turns to the weather and the climate, most people's thoughts naturally drift upward toward the clouds, but Jessica Oster's sink down into the subterranean world of stalactites and stalagmites.
Researchers use seismic signals to track above-ground explosions
Lawrence Livermore researchers have determined that a tunnel bomb explosion by Syrian rebels was less than 60 tons as claimed by sources.
Pockmarks on the lake bed
An unusual and unexpected discovery: on the floor of Lake Neuchâtel, geologists have happened upon huge underwater craters—some of the largest in the world to be found in lakes. They are not volcanic in ...
No major US hurricane landfalls in nine years
The United States hasn't experienced the landfall of a Category 3 or larger hurricane in nine years – a string of years that's likely to come along only once every 177 years, according to a new NASA study.
NASA research reveals Europa's mystery dark material could be sea salt
NASA laboratory experiments suggest the dark material coating some geological features of Jupiter's moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation. The presence ...
Scientists simulate gravity waves propagating toward space
Just as waves ripple across a pond when a tossed stone disturbs the water's surface, gravity waves ripple toward space from disturbances in the lower atmosphere.
