Graphical illustration and exploration of atmospheric data, like those from the 2006 ASA Data Exposition, is challenging. We chose to employ a two-step process, which consisted of exploring the presented data (1) from a ‘global’ view by simultaneously displaying the spatial and temporal components of individual variables in the data set using a geographic grid of polar coordinate plots or circular histograms that incorporated elevation as a background color, and (2) from a ‘local’ view by displaying the relationships between multiple variables at specific geographic locations and/or time points/periods (selected via step 1) using scatterplot matrices.
