Atmospheric limb sounding

Retrieves vertical profiles of atmospheric composition (O3, H2O, temperature) from limb or solar/stellar occultation geometry; high vertical resolution makes it suited for stratospheric and upper-tropospheric science.

Profile retrieval via optimal estimation or radiative transfer inversion against solar Fraunhofer lines. Limb geometry provides the vertical resolution that distinguishes this class from nadir column-mapping methods; tangent-height stepping yields profiles rather than integrated columns.
