Venus atmospheric profiles - From SPICAV-SOIR on board VEx version w24.00

Vertical profiles of density of species in the upper atmosphere of Venus at the terminator. Data retrieved from calibrated spectra obtained with the SPICAV-SOIR instrument on board the Venus Express spacecraft.
This dataset also contains upper limits of other species as well as pressure and temperature.

The retrieval method and the derived data is presented and analysed in several papers. See:

CO2, CO, H2O, HDO, H35Cl, H37Cl, HF: Mahieux et al. (2023a - https://doi.org/10.1016/j.icarus.2023.115713)
SO2, detection of OCS, CS, CS2, and SO3, and upper limits of H2S and HOCl: Maheix et al. (2023b - https://doi.org/10.1016/j.icarus.2023.115556)
H2CO, O3, NH3, HCN, N2O, NO2, NO, and HO2 upper limits of detection: Mahieux et al. (2024 - https://doi.org/10.1016/j.icarus.2023.115862)

This dataset was presented in https://doi.org/10.1016/j.pss.2017.04.022 for description of the dataset on the Vespa portal and an update was provided in the addendum https://doi.org/10.1016/j.pss.2024.105842

VOtables (.xml files) for each molecule detected by SOIR and for each orbit where SOIR was operating.
The density "n_", logarithm of the density "log_n_" and volume mixing ratio "vmr_" are provided for different smoothing by a moving average with windows varying from +/-0.1 to +/- 1 scale height (by step of 0.1).
For species with only upper limits (H2S, HOCl, H2CO, O3, NH3, HCN, N2O, NO2, NO, HO2): the files contains three fields: altitude, upper limit and error.
The corresponding uncertainties on the vertical profiles are the variables starting with "err_"

The files also contains the vertical profile of pressure "p" and temperature "t". The data concerning the geometry of the measurements: solar longitude, and local time, latitude, longitude, and Julian date corresponding to the profile are also provided in the same files.

For aerosols, see the older version w23.00.
