Modeling Atmospheric Aerosols

Scientists from across the globe recently convened on the sandy beaches of Duck, NC, for a three-week experiment called Electro-Optical Propagation Assessment in Coastal Environments (EOPACE). Sponsored by the Office of Naval Research, EOPACE is a collaboration between the United States, The Netherlands, the United Kingdom, Canada, Australia and Poland to improve the atmospheric aerosol models for predicting infrared propagation near the ocean surface and in coastal environments. Atmospheric aerosol propagation models are important to the Navy because sensors used to detect incoming threats, such as missiles and submarine periscopes operate in the infrared spectrum. Since aerosols create refraction in sensors' beams, the Navy needs to be able to predict the presence, absence and magnitude of aerosols in this particular atmospheric layer. Experiments will run eight hours a day, five days a week through March 12, 1999. Platforms for the experiments include aircraft, a surface boat and a satellite.
