EcoLight-S(ubroutine) is an extremely fast RTE (radiative transfer equation) solver developed for use as the optical component of coupled physical-biological-optical ocean ecosystem models, or as the radiative transfer forward-model core of implicit inverse models.

After Curtis Mobley, the developer of EcoLight-S, retired from Sequoia in December 2016, EcoLight-S became a product of Numerical Optics, Ltd. and is managed by Dr. John Hedley.  For further information, licensing, and user support please contact Numerical Optics at https://www.numopt.com/
