At Atmospheric and Environmental Research (AER), we help government agencies better anticipate and manage climate- and weather-related risks. 

We prepare agencies like NOAA, NASA and the Department of Defense, along with large insurance, investment and energy companies to anticipate, manage, react to and profit from weather and climate related risk. We serve our clients by providing state-of-the-art research, development and analysis delivered in reports, databases and software solutions.

AER's world-renowned scientists and engineers are helping government agencies to understand weather and climate risk, predict impacts, and take action.

Our scientists – more than 85 of whom hold PhDs or other advanced degrees – are globally recognized for being at the forefront of their scientific fields. Areas of expertise span climate change, defense, hydrology, meteorology, oceanography, space, remote sensing, and atmospheric and environmental science. 

At AER we're dedicated to the advancement of scientific understanding of the atmospheric, climate and weather, ocean, and planetary sciences.  Through externally funded research conducted by our in-house scientific staff, and often in collaboration with world-renowned scientists at academic and other research institutions, we have developed analytical tools to help measure and observe the properties of the environment and to translate these measurements into useful information to take action. We have clients in the private and public sectors around the world. 

Dr. Cohen joined Atmospheric and Environmental Research in 1998. Prior to AER, he spent two years as a National Research Council Fellow at the NASA Goddard Institute for Space Studies after two years as a research scientist at MIT’s Parsons Laboratory. Cohen received his Ph.D. in Atmospheric Sciences from Columbia University in 1994 and has since focused on conducting numerical experiments with global climate models and advanced statistical techniques to better understand climate variability and to improve climate prediction. Cohen develops AER’s long range forecast products for commercial clients who include some of the largest investment firms in the US. He's been interviewed on television, the Wall Street Journal, Boston Globe, and Investor’s Business Daily, among others. His work is highlighted by the National Science Foundation (NSF).

Dr. Cohen has a Research Affiliate appointment in the Civil Engineering Department at Massachusetts Institute of Technology (MIT) and is a member of the American Meteorological Society (AMS) and the American Geophysical Union (AGU). He has published over two dozen articles on seasonal forecasting in their journals and others. Most recently, Dr. Cohen was appointed Associate Editor of the Journal of Climate, a peer-reviewed publication of the AMS.
