Earth and Planetary Radiative Transfer | About

The applications for atmospheric radiative transfer models are wide-ranging, including forward modeling of remote sensors, accurate retrieval of remotely-sensed information, calculation of parameters for atmospheric correction of remotely-sensed imagery, and support of synthetic scene generation.  CPI has domain expertise in all of these areas and has developed mature models and software tools used by NASA, university and national labs, and private industry.


Dr. Jennifer Tate

jennifer_tateScene Generation Lead

Dr. Jennifer Tate maintains CPI's atmospheric radiative transfer codes, synthetic scene generation models, and atmospheric correction tools.  She has served as Co-Investigator on two Missile Defense Agency Phase II SBIR projects for the development of large-scale physics-based models for synthetic scene generation: the GAIA™ model for generating terrain and cloud imagery, and the OCEANUS™ model for generating background ocean scenes.

In support of these models Dr. Tate has also been involved in the development of the AETHER™ atmospheric radiative transfer model, which supplies inputs for both GAIA™ and OCEANUS™.  Dr. Tate received her Ph.D. in physics from The Ohio State University in 2004.

 


Mr. Scott Evans

Chief Technology Officer

Mr. Evans is an expert in UV spectroscopy, energetic particle transport, photon transport, optical backgrounds and optical remote sensing. He has over 25 years of experience in numerical methods applied to linear transport theory and has developed and maintained many of CPI's state-of-the-art theoretical models, including the Atmospheric Ultraviolet Radiance Integrated Code (AURIC), Boltzmann 3 Constituent (B3C) code, and the Line-of-Sight Integrator in 3D (LOSI_3D).

Mr. Evans has applied CPI's models towards an improved understanding of photon and electron characteristics in the upper atmospheres and ionospheres of Earth, Titan, Pluto, and Mars. As a member of the MAVEN science team, Mr. Evans has extended the AURIC and B3C models to the FUV-MUV dayglow from the Martian atmosphere. The Mars version of AURIC is being used to perform operational temperature and neutral and ion density retrievals from IUVS observations at Mars. Mr. Evans is also a Co-I for the Global-scale Observations of the Limb and Disk (GOLD) mission and oversees the use of CPI models and associated algorithms in the GOLD Level 2 data processing pipeline.
