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.
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.
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.
Mercury-laden fog swirls over coastal California, scientists find
What do the roof of a building in a West Coast redwood forest, a bluff in California chaparral, and a research vessel in Monterey Bay have in common?
Mars has belts of glaciers consisting of frozen water
Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, ...
Warming slow-down not the end of climate change, study shows
A slow-down in global warming is not a sign that climate change is ending, but a natural blip in an otherwise long-term upwards trend, research shows.
Computer models show significant tsunami strength for Ventura and Oxnard
Few can forget the photos and videos of apocalyptic destruction a tsunami caused in 2011 in Sendai, Japan. Could Ventura and Oxnard in California be vulnerable to the effects of a local earthquake-generated tsunami? Yes, ...
Shifting winds, ocean currents doubled endangered Galápagos penguin population
Shifts in trade winds and ocean currents powered a resurgence of endangered Galápagos penguins over the past 30 years, according to a new study. These changes enlarged a cold pool of water the penguins rely on for food and ...
Pollen and clouds: April flowers bring May showers?
The main job of pollen is to help seed the next generation of trees and plants, but a new study from the University of Michigan and Texas A&M shows that the grains might also seed clouds.
Existing crop models can forecast yield in uncertain climate conditions
A study led by Indiana State Climatologist Dev Niyogi of Purdue University has determined that existing crop models can reliably forecast corn yields during times of climate variability, specifically the El Niño and La Niña ...
Greenland's undercut glaciers melting faster than thought
Greenland's glaciers flowing into the ocean are grounded deeper below sea level than previously measured, allowing intruding ocean water to badly undercut the glacier faces. That process will raise sea levels around the world ...
