Sequoia Senior Scientist Curtis Mobley has developed several sophisticated numerical models for oceanic radiative transfer calculations. The best known of these is HydroLight, which computes underwater and water-leaving light fields (radiances, irradiances, reflectances, and related quantities) for plane-parallel water bodies. HydroLight is a stand-alone software package intended for use as a research tool. Its emphasis is on generality and accuracy of the solutions, with computer time being secondary. HydroLight must be used if the angular distribution of the radiance is needed.
EcoLight-S(ubroutine) is a software package developed for light computations in coupled physical-biological-optical ocean ecosystem models, for which only photosynthetically available radiation (PAR), in-water irradiances, or nadir-viewing remote-sensing reflectance are required. Because ecosystem models often require light calculations at thousands of grid points and time steps, and inverse models may require thousands of solutions of the radiative transfer equation, EcoLight-S emphasizes extremely fast run times at the expense of a user-selectable level of accuracy.
In addition to the commercial HydroLight and EcoLight-S products, we have a proprietary Backward Monte Carlo model (named BMC3D) that computes underwater radiances and irradiances for three-dimensional geometries such as occur, for example, in shallow waters with sloping bottoms or spatially variable bottom reflectances. We also have a proprietary Monte Carlo code, BSFPSF, which computes beam spread functions and point spread functions, which are the foundation of underwater visibility studies. The BMC3D and BSFPSF codes are not commercial products. However, these codes are available to solve specific problems on a contract basis. Special versions of HydroLight can also be developed for particular user needs on a contract basis.
