Correction of the Observatoire Haute Provence electrochemical concentration cell (ECC) ozonesonde long-term data record over the 2002–2007 period

Data sets

O3 profiles data using 2025-corrected ECC ozonesonde measurements at OHP Gérard Ancellet and Sophie Godin-Beekmann https://doi.org/10.25326/855

LS/Aura Level 2 Ozone (O3) Mixing Ratio V005 M. Schwartz et al. https://doi.org/10.5067/Aura/MLS/DATA2516

Tropospheric O3 profiles data using ECC ozonesonde measurements at the OHP Gérard Ancellet https://doi.org/10.25326/293

Stratospheric ozone data profiles using LIDAR (DIAL) measurements at OHP S. Godin-Beekmann https://doi.org/10.25326/292

Short summary

The ozone sounding data from the electrochemical concentration cell (ECC) at the Haute Provence Observatory (OHP) for the period 1991–2020 were homogenized in 2022 using the recommendations of the ECC data quality assessment committee. Comparisons with lidar and satellite observations show that the ECC pump temperature measurements for the period 2002–2007 need to be corrected in addition to the 2022 homogenization. This correction improves the consistency of the ECC ozone dataset at the OHP.
