The Atmospheric Ultraviolet Radiance Integrated Code (AURIC) is a software package developed by Computational Physics, Inc. (CPI) for the Air Force Phillips Laboratory (currently the Air Force Research Laboratory [AFRL]) for upper atmospheric radiance modeling from the far ultraviolet to the near infrared. It effectively extends the MODTRAN® code for calculating atmospheric transmittance and radiance (infrared and Rayleigh plus aerosol scattering of sunlight) to altitudes above 100 km and wavelengths down to 80 nm.
Many enhancements have been made to AURIC since its inception, including a more comprehensive chemistry model (for neutral and ionospheric species), new radiative transfer capabilities, the option of performing photoelectron energy degradation with or without transport, updates to electron impact cross sections (Majeed and Strickland, 1997; Strickland et al., 1997), and the addition of new emission features. AURIC is currently in use by a number of organizations: AFRL, NRL, and JHU/APL. A summary of AURIC's modeling capabilities can be found in the AURIC brochure.Examples of applications papers using AURIC are listed in the references below.
