All previous work in lightning reconstruction had two primary components: acquiring thunder claps from a calibrated set of locations and analyzing the sound recorded at each location to determine the structure of the lightning that produced the thunder clap. To design the more ambitious system that we and our client envisioned, additional components were necessary for fast and easy visualization of the lightning data, for storage and quick retrieval of lightning data, and for remote control of thunder recording. In addition to this extra functionality, we had to account for the possibility that these modules could run on different computers. Thus, the TREMBLE system evolved to have five major software components: a data acquisition module, a sound analysis module, a visualization module, a storm/data manager, a scheduling manager. We consider all necessary hardware to be in one "module," since the hardware's purpose is to detect the lightning strikes, record the thunder claps, and give our system a set of digitized signals to analyze.
