This data results from radio sounding of the ionosphere by the Alouette I satellite. Data were collected from May 1, 1963 to December 31, 1963.
These datasets have been converted from their legacy file structures and encoding schemes so they can be used by contemporary computers that are based upon the ASCII character-encoding scheme. Each dataset will require specialized software such as a statistical tool, to interpret and analyze the content in each file. The attached codebook describes the file’s structure and defines the variables contained in each field. Each code book is a compilation of the summary description of the dataset as provided by the creating department. As such, it is available in English only.
