.. _optproperties: ****************** Optical Properties ****************** Optical property objects provide the absorption, extinction and scattering of individual molecules/particles in the atmosphere. They are created using the :class:`ISKOpticalProperty` class and are used by the radiative transfer engines to calculate scattering, extinction and absorption in the atmosphere. Many optical property classes are solely focused on the properties of a single molecule while a few classes support several species (eg Hitran). The majority of optical properties depend upon atmospheric state, typically local pressure and/or temperature, and this information is provided to the optical property object as a climatology and location (lat, lon, height, utc). ============================================== ====================== ===================================================== Optical Property Extension Description ============================================== ====================== ===================================================== :ref:`optical_basspaurlinear` :ref:`sasktran_core` O3, Bass-Paur Linear :ref:`optical_basspaurquadratic` :ref:`sasktran_core` O3, Bass-Paur Quadratic :ref:`optical_o3dbm` :ref:`sasktran_core` O3, Daumont, Brion and Malicet 1992. :ref:`optical_o3gomeburrows` :ref:`sasktran_core` O3, Burrows with GOME instrumenmt :ref:`optical_o3osirisres` :ref:`sasktran_core` O3, Convolved cross-section used for early OSIRIS analysis :ref:`optical_o3sciabogumilv3` :ref:`sasktran_core` O3, Bugumil for SCIA.
