Global distribution of ozone vertical profiles retrieved from NOMAD-UVIS/TGO, presented in Piccialli et al. 2023

This dataset is presented in "Ozone observed by TGO/NOMAD-UVIS solar occultation: an inter-comparison of three retrieval methods" by A. Piccialli, A.C. Vandaele, et al. 2023.: https://doi.org/10.1029/2022EA002429)

Each file name indicates the retrieval method:

  • FOEM: Full occultation Optimal Estimation Method
  • OP: Onion Peeling
  • DOP: Direct Onion Peeling

Files are in the HDF5 format. Each file contains:

Geometry:

  • LST = local solar time [hrs]
  • Ls = solar longitude [degree]
  • lat = latitude [degree]
  • lon = longitude [degree]
  • orbit = file name of each occultation
  • day = day of observation
  • month = month of observation
  • year = year of observation

Science

  • For each entry: [number of columns = number of occultations analyzed, number of rows = 600 (altitude grid)]
  • Nd_O3 = ozone number density [cm-3]
  • Nd_O3_Err = error on ozone number density [cm-3]
  • z = altitude above aeroid [km]

Filtering (present only if relevant to the method):

  • DoF = Degree of Freedom
  • DL = detection limit [cm-3]
  • chi2_O3 = chi2 of the retrieval including ozone
  • chi2_no_O3 = chi2 of the retrieval without ozone

The filtering criteria Delta_chi2 described in our paper is derived as:

  • Delta_chi2 = chi2_no_O3/chi2_O3
