description: This Envisat SCIAMACHY Level 2 Total column densities and stratospheric profiles v7.1 dataset is generated from the full mission reprocessing campaign completed in 2023 under the _$$ESA FDR4ATMOS project$$ https://atmos.eoc.dlr.de/FDR4ATMOS/ . It provides atmospheric columnar distributions and stratospheric profiles for various trace gases based on the Level 1b version 10 products. This SCIAMACHY Level 2 dataset contains total column densities of O3, NO2, OClO, H2O, SO2, BrO, CO, HCHO, CHOCHO and CH4 retrieved from Nadir measurements. Additionally, cloud parameters (fractional coverage, top height, optical thickness) and an aerosol absorption indicator are enclosed. Stratospheric profiles of O3, NO2, and BrO are derived from limb measurements, along with flagging information for different cloud-types. Tropospheric NO2 and BrO columns are retrieved combining limb and nadir measurements. This SCIAMACHY Level 2 dataset version 7.1 replaces the previous version 6.01. Users are strongly encouraged to make use of the new datasets for optimal results. For limb O3 profiles, a separate product derived from the previous Version 6 processor is provided distinctly -> _$$SCIAMACHY Level 2 - Limb Ozone [SCI_LIMBO3]$$ https://earth.esa.int/eogateway/catalog/envisat-sciamachy-ozone-stratospheric-profiles-sci_limbo3 . This is because the V7.1 limb ozone data is unsuitable for long-term change studies due to its divergent behavior from earlier processor versions, particularly from 2009 onwards. This divergence stems from residual deficiencies in the Level 1, resulting in a vertical oscillating pattern in the drift and bias profiles. In contrast, Version 6 limb ozone data does not exhibit these oscillations in bias and drift. Further details on this issue can be found in the _$$latest README$$ https://earth.esa.int/documents/d/earth-online/rmf_0014_sci_____2p_l2v7-1 file. The new products are conveniently formatted in NetCDF. Free standard tools, such as _$$Panoply$$ https://www.giss.…
