Remote sensing data is complicated, very complicated! It is not only geospatially tricky but also indirect as the sensor measures the interaction of the media with the probing radiation, not the geophysics. However the problem is made tractable by the large number of algorithms available in the Scientific Python community, what is needed is a common data model for active remote sensing data that can act as a layer between highly specialized file formats and the cloud of scientific software in Python. This presentation motivates this work by asking: How big is a rainshaft? What is the natural dimensionality of rainfall patterns and how well is this represented in fine scale atmospheric models. Rather than being specific to the domain of meteorology we will break down how we approach this problem in terms what tools across numerous packages we used to read, correct, map and reduce the data to forms able to answer our science questions. This is a "how" presentation, covering signal processing using linear programming methods, mapping using KD Trees, and image analysis using ndimage and, of course graphics using Matplotlib.
