The CEDAR Tomography Facility (COTIF) would thus bring, literally, the third dimension to optical aeronomy over the full altitude domain of mesosphere to thermosphere (80-600 km) defined by such emission features as metallic layers to SAR arcs. The proposed effort is for two years, using a team of researchers experienced in the design, construction and science yield of optical diagnostics. Science Team members from other institutions provide advice and guidance on final design goals, field test issues and full off-site campaign use. Automation, telescience access and super-computer utilization offer extraordinary opportunities for CEDAR post-doctoral and graduate student training in a first of its kind tomographic facility. ***
