        | Zusammenfassung |  
        | We review the main factors driving the calculation of the tangent height of spaceborne limb
  measurements: the ray-tracing method, the refractive index model and the assumed atmosphere. We
  find that commonly used ray tracing and refraction models are very accurate, at least in the
  mid-infrared. The factor with largest effect in the tangent height calculation is the assumed
  atmosphere. Using a climatological model in place of the real atmosphere may cause tangent height
  errors up to ± 200 m. Depending on the adopted retrieval scheme, these errors may have
  a significant impact on the derived profiles. |
