The Split Window Difference field (SWD, the 10.3 µm brightness temperature minus the 12.3 µm brightness temperature) can be used to identify regions of moisture and dust in the atmosphere. (Click here for a previous blog post). On 5 June 2018, the SWD showed a strong gradient over the upper Midwest, with... Read More
