Supporting Information for "Nine Martian Years of polar caps observations by SPICAM-IR"

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 (&gt;20).<br> <strong>Data Set S1 </strong><br> 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 (&gt;20) and all required observational geometry in a form of csv table.
