Computational Physics, Inc.  was founded to perform advanced scientific research and use its findings to characterize radiation properties of the Earth's upper atmosphere and develop new remote sensing techniques for better understanding the upper atmosphere and ionosphere.   Today, it continues to be active in these areas but has broadened its work-base to also address remote sensing of the middle and lower atmospheres, ionospheric effects on signals, data assimilation techniques for global ionospheric specification, software architectures using object oriented concepts for distributed processing, and electromagnetic phenomenologies for radar cross section determinations.
