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.
A new NASA analysis of 30-years of satellite data suggests that a previously observed trend of high altitude clouds in the mid-latitudes shifting toward the poles is caused primarily by the expansion of the tropics.
Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported.
Many factors related to warming will conspire to raise the planet's oceans over coming decades—thermal expansion of the world's oceans, melting of snow and ice worldwide, and the collapse of massive ice sheets.
The amount of sea level rise in the Pacific Ocean can be used to estimate future global surface temperatures, according to a new report led by University of Arizona geoscientists.
New findings based on a year's worth of observations from NASA's Van Allen Probes have revealed that the ring current - an electrical current carried by energetic ions that encircles our planet - behaves in a much different ...
A new University of Colorado Boulder study comparing dissolved black carbon deposition on ice and snow in ecosystems around the world (including Antarctica, the Arctic, and alpine regions of the Himalayas, Rockies, Andes, ...
The ocean of Jupiter's moon Europa could have the necessary balance of chemical energy for life, even if the moon lacks volcanic hydrothermal activity, finds a new study.
New research, led by the University of Southampton, suggests that the release of methane from the seafloor was much slower than previously thought during a rapid global warming event 56 million years ago.
Iron particles catching a ride on glacial meltwater washed out to sea by drifting currents is likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study.
The University of California, Berkeley's worldwide network of smartphone earthquake detectors has recorded nearly 400 earthquakes since the MyShake app was made available for download in February, with one of the most active ...
