Most people think of the Sahara Desert when they think of dust storms, but the high latitudes experience dust events too. Scientists have limited understanding of dust storms in the high latitudes because on-the-ground observations are really sparse. Your photographs of dust storms in high latitudes are incredibly needed. High latitude is defined as 50-90 degrees North and 40-90 degrees South. With limited ways to gather data, your photographs could fill a critical data gap for scientists.
