This dataset contains all Radiative Transfer (RT) results made for the paper: > Coutelier et al. 2021 - Icarus. > Distribution and intensity of water ice signature in South Xanadu and Tui Regio > doi: 10.1016/j.icarus.2021.114464 The data are stored in 4 zipped-folders named with the VIMS cube id and the tested model (when available): - C1481624349_1_FM_diff_FH.zip - C1481624349_1_FM_eq_FH.zip - C1590648776_1.zip - C1809727868_1.zip In these folders, each VIMS pixel is stored in 2 csv-files, with the following patterns: 1. <CUBE_ID>_<PIXEL_SAMPLE>-<PIXEL_LINE>[_<TESTED_MODEL>]_spectra.csv 2. <CUBE_ID>_<PIXEL_SAMPLE>-<PIXEL_LINE>[_<TESTED_MODEL>]_albedo.csv The first one, starts with a commented header describing the radiative transfer model inputs and outputs: - CUBE_ID: the VIMS cube id (`C1234567890_1` format) - SAMPLE: the pixel sample number. - LINE: the pixel line number. - NKS: the number of correlated-k values used in the RT model. - MAX_VAL_NLEGP: the maximum number Legendre polynomial coefficient in the phase function. - SURFACE: the surface reflection type (Lambert in our case). - SOLARFLUX: the incident flux (adjusted from the incident angle). - ALT_MAX_M: the max altitude of the model grid (in meter). - RADIUS_MONO: The aerosols monomer radius (in meter). - N_MONO: the number of monomers. - DF: the aerosols fractal dimension. - FH: the haze scaling factor. - FM: the mist scaling factor. - HAZE_ALT_TRANS: the altitude of transition between mist and haze (in meter). - X2: the quadratic error between the data and the output. - PHASE: the surface phase angle (in degree). - EMI: the surface emergent angle (in degree). - INC: the surface incident angle (in degree). - SOLAR_MU: Opposite of the cosine of the incident angle (SHDOMPP). Cosine of the incident angle (SPSDISORT) - MU_OUT: the cosine of emergent angle. - PHI_OUT: the azimuth of the emergent angle (in degrees). Then, it contains the original and the retrieved spectra: - Column 1: the VIMS band channel number. - Column 2: the VIMS channel central wavelength (in meter). - Column 3: the original VIMS pixel I/F. - Column 4: the RT model retrieved I/F. The second file, contains only the surface albedo retrieved with the RT model with its associated error: - Column 1: the VIMS channel central wavelength (in meter). - Column 2: the original surface albedo retrieved (negative values were set at 0). - Column 3: the adjusted surface albedo retrieved with wider atmospheric windows. [*] - Column 4: the upper error value of the surface albedo retrieved in the model. - Column 5: the lower error value of the surface albedo retrieved in the model. [*]: In order to keep a record of edge effects. All null values were replaced with NaN but the negative values are kept. Notes ----- For the VIMS cube `C1481624349_1`, we performed two different tests: 1. with different haze and mist parameters FH == FM (default). 2. with the same haze and mist parameters FH != FM. The radiative transfer retrievals were performed with `SHDOMPP` solver except on the VIMS cube `C1809727868_1` where we used `SPSDISORT` solver (suffixed with `_SPS` in the filename). Finally, we also provide a Jupyter Notebook (`Display_cubes.ipynb`) to help visualize the data. This file can be open locally or with Jupyter Notebook Viewer at: https://nbviewer.jupyter.org We provide as well the three calibrated VIMS-IR cube files ('C<CUBE_ID>_ir.cub') we worked with.
