RAL's mission is to conduct directed research that contributes to the fundamental understanding of the atmosphere and related physical, biological, and social systems; to support, enhance, and extend the capabilities of the scientific community, and to develop and transfer knowledge and technology for the betterment of life on Earth. This collection contains a selection of digitized films and born-digital presentations from RAL projects, with a focus on transportation safety. Support for this collection was provided by a grant from the Center for History of Physics, American Institute of Physics.
