Introduction:

Due to the limited spatial coverage of ozonesonde measurements, Satellite techniques play an important role in deriving global tropospheric ozone. The various satellite retrieval methods, however, vary significantly in their derived values of tropospheric column ozone. We evaluate the correspondence between various satellite derivation techniques and model calculations of tropospheric ozone and also evaluate this correspondence in both the spatial and temporal morphology of ozone.
