Atmospheric Effects on Transfer of Heat and Environmental Radiation (AETHER™)

aether_thumbThe Atmospheric Effects on Transfer of Heat and Environmental Radiation (AETHER™) software product is a band-model atmospheric radiative transfer code developed from the Department of Defense standard model Moderate Spectral Atmospheric Radiance and Transmission (MOSART). AETHER™ solves the radiative transfer equation in a fully three-dimensional, spatially varying atmosphere, and outputs the full radiative environment for any spectral band in the ultraviolet through microwave spectral regions (0.2 μm to infinity, or 0-50,000 cm-1). Outputs include path radiance, solar/lunar irradiance, skyshine, and transmission, all as a function of altitude. Terrain material temperatures for a large number of materials can also be calculated for the given atmospheric conditions. AETHER™ supports a wide variety of viewing geometries, including Earth-based, space-based and airborne. In addition multiple geometries can be included in a single execution of the code, each for a different time of day, making AETHER™ a fully four-dimensional code.

AETHER™ was developed from MOSART, but contains numerous upgrades relative to the last released version of MOSART (V2.0.4). AETHER™ has been completely re-written in Fortran 95/2003/2008, allowing for significant improvements in code structure and efficiency relative to MOSART. A large number of global environmental databases have been added to AETHER™, allowing for better characterization of the background environment based on latitude and longitude. Several molecular band parameters databases have been added, allowing for increased options in spectral resolution as well as improved accuracy. An upgraded geometry input capability allows for greater flexibility in defining observer-source geometries, including as mentioned above the ability to specify a different time of day for each geometry. And finally a number of bug fixes have been implemented as the code was developed.

Applications for AETHER™ include atmospheric correction, scene generation and signature prediction simulations.
