Spatial extent of dust storm boundaries in the Mars Dust Activity Database


The Mars Dust Activity Database (MDAD) v1.1 is expanded to include all dust storm instance boundaries in MDAD v1.0 from the Mars Color Imager years (Mars Years 28–32). Dust storm boundaries are provided in two formats to ease adoption by the community: as netCDF masks and in comma separated value files. We demonstrate the utility of dust storm boundaries by showing how the frequency of dust storms evolves with season across the surface. The highest dust storm frequencies occur in the southern hemisphere around L_s = 0° and L_s = 270° and in the northern hemisphere around L_s = 180° and L_s = 300°.
