We created a new animation that shows the observed evolution of temperature anomalies throughout the Northern Hemisphere landmasses based on snow cover alone. We composited daily temperatures (using a five day filter) of years with observed high Eurasian October snow cover minus low Eurasian October snow cover. The animation runs from September 1 through February 28. You can view it on the Arctic Oscillation blog toward the bottom of the page.

Research performed by AER scientists Dr. Daniel Gombos and Dr. Ross Hoffman is featured on the NSF Science, Engineering, and Education (SEE) innovation website.

AER has received a highly coveted Supplier Excellence Award from Northrop Grumman Corporation’s Information Systems (NGIS) sector for technical innovation and quality products and services. AER was recognized for its work on the System Engineering Maintenance and Sustainment (SEMS) II program at the U.S. Air Force Weather Agency, the largest supplier of terrestrial and space weather data for military users worldwide.

AER is proud that 10 of our scientists were the lead authors presenting their research on a wide range of topics at the American Geophysical Union (AGU) annual Fall meeting. In all, 33 AER scientists contributed to 28 research studies in 7 science categories ranging from greenhouse gases to land surface processes to space weather.

AER scientists involved in greenhouse gas (GHG) research, Janusz Eluszkiewicz and Thomas Nehrkorn, are co-authors of a Harvard-led study "Anthropogenic emissions of methane in the United States" just published in the Proceedings of the National Academy of Sciences (PNAS) and receiving considerable attention worldwide for its conclusion that methane emissions in the U.S. are significantly greater than previous estimates.

When the U.N.’s IPCC released the WG-1 AR5 report, we were proud to see the breadth of research by AER scientists cited in the report. It’s an indication that AER scientists have helped advance the scientific discourse about the Earth’s climate by providing research covering a broad range of topics from the ocean depths to the top of the atmosphere.

Knowledge of changes in ocean bottom pressure, and their relation to fluctuations in sea surface height, is important for understanding aspects of ocean circulation and climate variability; for example, facilitating estimation of ocean heat content variations and elucidating causes for regional sea level variability. However, historical measurements of bottom pressure have been extremely sparse, limiting observational understanding of the nature of ocean bottom pressure behavior on scales relevant for climate studies.

Electrical blackouts are on the rise in the US, costing businesses and consumers more than $100 billion annually and inconveniencing millions of people. But so far insurers, companies, municipalities, government agencies and other organizations lack a widely available and dependable tool to calculate the financial consequences. Understand and assess blackout risks

Lloyds and AER published a ground-breaking study of solar storm risk to the electric grid in North America. The Space Weather Study by Lloyds and AER analyzes the likelihood of extreme geomagnetic storms, the specific vulnerabilities of the North American power grid, the regions at highest risk and the implications for the insurance industry and society generally.
