Investigation of satellite vertical sensitivity on long-term retrieved lower tropospheric ozone trends

<p>Regional time-series (monthly mean) of lower tropospheric column ozone (LTCO3; 0-6 km or surface to 450 hPa) between 2008 and 2017 from three satellite products and an Earth System Model (UKESM1.0 - https://ukesm.ac.uk/). The regions of focus are North America, Europe and East Asia based on the HTAP-2 land mask (https://htap.org/). The three satellite products are from the Ozone Monitoring Instrument (OMI) (RAL Space - https://www.ralspace.stfc.ac.uk/Pages/Remote-Sensing.aspx), the Infrared Atmospheric Sounding Interferometer (IASI) FORLI (Fast Optimal Retrievals on Layers for IASI) scheme (https://iasi.aeris-data.fr/cos_iasi_b_arch/) and the IASI SOFRID (SOftware for Fast Retrievals of IASI Data) scheme (https://iasi-sofrid.sedoo.fr/). These data have been used to investigate long-term trends and investigation of satellite long-term discrepancies in retrieved LTCO3.
