• Significant optimisations to the model since the last release, primarily through LoopVectorization.jl and other SIMD operations.
• Also supports better surface optical properties, deriving reflectivity and emissivity from empirical single-scattering data.
• Tests and now more rigorous and comprehensive
• Minor bugfixes
