Distinct mineralogy and age of individual lava flows in Atla Regio, Venus derived from Magellan radar emissivity

This repository contains the supplementary material associated with Brossier et al. (under review for JGR Planets), and includes:<br><i>Atla_sar.tif </i>and <i>Atla_emis.tif</i>: High resolution SAR image (75 m.px^-1, and left-looking) and emissivity map (4.6 km.px^-1), respectively, centered on Atla Regio. Links to the USGS websites are available below. <br><br><i>Sapas_units.dbf, .prj, .shp, .shx</i> ... (same with Maat and Ozza): Shapefiles and auxiliary files for each volcano with their lava flow units mapped in this work. <br><br><i>Sapas.txt, Ozza.txt, Maat.txt</i>: Text files containing Magellan altitude, emissivity, derived permittivity and also coordinates values for each pixels within lava flow units mapped per volcano. Altitude is given as planetary radius in km, while the permittivity is calculated after Campbell (1995) using the smooth criterion (see details in main text).<br><i>modeled_excursions.xlsx</i>: Excel table with altitude and permittivity values used to reproduce the excursions after using a ferroelectric model from Shepard et al. (1994) (see details in main text).<br>
