The formation and evolution of cold diffuse clouds (CDCs), the parent objects of dense molecular clouds, affects both the star formation process and that of larger-scale galactic evolution. We have begun a pilot study of one CDC's dust content, with the goal of quantifying the abundances of different types of dust and relating these to the relative abundance of molecular gas, the cloud's physical properties, and its general stage of development. Using photometry from AKARI and other surveys, we have extracted a sample spectral energy distribution (SED) of the CDC dust thermal emission over the near-infrared to submillimeter range. The extracted SED closely resembles others in the literature, confirming our isolation of the cloud emission from other sources along the sight line. We plan to fit this SED with dust models at each position in the cloud, automating our procedure to map out the structure of this CDC and others.
