Results of the tests that deserve further investigation

There are a lot of possibile future applications and studies to be performed, such as:

  • Fusion of IASI-EPS-O3 and IASI-FORLI-O3
  • Since the EUMETSTAT products have limited time coverage, consider also IASI-AERIS products and evaluate the differences with the correspondent EUMETSAT products, when available.
  • IASI-FORLI-EUMETSAT: add the study of Sn eigenvalues to discuss the results of CDF(2015) auto-consistency test.
  • For IASI-CO-METOP C the product has been enriched and allows additional tests (https://acsaf.org/docs/pum/Product_User_Manual_IASI-C_CO_Nov_2021.pdf) For example also the total column AK is available and this could be used to study the comparison of CDF applied in profile space and total column space.
  • Consider also OMPS-NOAA-O3 datasets available here

Other Eligible Data Sets

Below is a list of other datasets to consider, grouped by satellite. The list was created by looking for level 2 atmospheric profiles retrieved using optimal estimation techniques in the following data portals:

  • https://evdc.esa.int/search/satellite/
  • https://navigator.eumetsat.int/start
  • https://www.earthdata.nasa.gov/
  • https://www.star.nesdis.noaa.gov/

Both operating and non-operating instruments/satellites have been considered.
