Correction for Stratospheric aerosols

Stratospheric aerosol are generated mostly by large volcanic eruptions. The corresponding optical thickness is, a few months after the eruption, well mixed over latitudinal bands. Ground based as well as satellite limb measurements yield the a stratospheric aerosol optical thickness. POLDER processing algorithm are designed to make use of such estimates for a correction of the stratospheric aerosol scattering. The correction is based on an a-priori stratospheric aerosol model.
