This dataset contains several additional figures and data for the "Nine Martian Years of polar caps observations by SPICAM-IR". Data and additional figures play special role in this publication, since we use a lot of different representations (seasonal, spatial and cap edges) of sparse dataset in our work. It also includes processed SPICAM-IR CO2 ice equivalent width and water index for orbits without artifacts or distortions and with normal signal-to-noise ratio (>20). Data Set S1 This Data Set (spicam_obs.csv) contains CO2 ice equivalent width and water index for orbits without artifacts or distortions and with normal signal-to-noise ratio (>20) and all required observational geometry in a form of csv table. In this file there are 13 following columns: orbit: name of orbit as in PSA 1B files spec_num: number of spectrum in this file starting from zero lat: center latitude of field of view lon: center longitude of field of view ls: solar longitude of observation local_time: local time of observation incidence: incidence angle alt_spc: altitude of observation, which determines FOV size co2ice_index: equivalent width of CO ice 1.43 m band h2oice_index: index of 1.5 m water ice band albedo: albedo at 1.37 m, out of major absorption bands snr: signal-to-noise ratio measure around 1.37 m, out of major absorption bands martian_year: Martian Year Using this dataset one can plot all of the figures in the original paper, except for spectra. Data Set S2 This Data Set (figure4.txt) contains data from Figure 4 in the original paper. Description of the figure: Diversity of ice spectra on south pole. (Blue on picture): Slab ice in winter, Ls: 144.15, latitude: -58.7, longitude: 257.58, orbit: 10902A01, 1.43 µm band width: 30.5 nm; (Orange on picture): Bright CO2 ice, Ls: 253.08, latitude: -86.23, longitude: 315.70, orbit: 1943A01, 1.43 µm band width: 16.4 nm; (Green on picture): Cryptic region with almost no CO2 ice, Ls: 213.12, latitude: -82.52, longitude: 122.06, orbit: 4169A01, 1.43 µm band width: 1.4 nm; (Red on ...
