Much better user experience--and in these examples the users could be high school students or teachers, college students, grad students, PIs, public policymakers, etc--users can do complex searching, filtering, previewing data images & plots, and selecting data over a wide variety of spatial and temporal bounds. They can also either directly download the data in a self-describing format (with metadata), or they can describe various kinds of post-processing that is done efficiently and quickly.
