Studies dynamic changes in Earth's neutral/ionosphere density in the ~140 km - 290 km altitude region. The wide spatial and temporal distribution of the data provided by DAILI over the course of its mission will improve the accuracy of operational models for both the neutral density and the ionosphere, and will help further the study of wave propagation and transport processes in the lower thermosphere.
