New Climatology of Martian Water Vapor Column Abundance Derived from NOMAD LNO Nadir Observations Over Martian Years 34-38

Repository of the data sets presented in the manuscript entitled "New Climatology of Martian Water Vapor Column Abundance Derived from NOMAD LNO Nadir Observations Over Martian Years 34-38" by F. Hendrick et al. This manuscript has been submitted to JGR: Planets in December 2025. The following data files (ascii column format) are made available (see also the headers of the files for a description of their content): + Full data set of H2O vertical column densities retrieved from LNO diffraction orders 167 and 169. This data set has been used to prepare Figure 7 of the manuscript (inter-annual variability over Martian Years 34 to 38). + Data set of H2O vertical column densities retrieved from LNO diffraction orders 167 and 169 where data corresponding to the Martian Year 34 global dust storm period (Ls=195°-230°) are removed. This data set has been used to prepare Figure 8 (mean seasonal variation over Martian Years 34 to 38) and Figure 9 (mean geographical variation over Martian Years 34 to 38, without and with scaling for topography) of the manuscript. + Data set corresponding to Figure 5 of the manuscript: comparison between LNO orders 167 and 169 H2O data from this work and from Crismani et al., JGR, 2021 + Data set corresponding to Figure 6 of the manuscript: comparison between LNO order 168 H2O data from this work and from Crismani et al., JGR, 2021 + Data set corresponding to Figure 10 of the manuscript: comparison between LNO orders 167 and 169 H2O data and co-located MGS/TES data + Data set corresponding to Figure 11 of the manuscript: comparison between LNO orders 167 and 169 H2O data and co-located EMM/EMIRS data + Data set corresponding to Figure 12 of the manuscript: comparison between LNO orders 167 and 169 H2O data and co-located GEM-Mars model data + New AOTF function data (Figure S4 of the Supporting Information).
