The report provides a user-oriented introduction to the archive structure and contents. The archive includes both documentation and data. A data set documentation report is prepared for each archived data set. The entries in the documentation are as follows: data set fact summary, a narrative description of experiment and data, special information, references, a description of archive data files, contacts (names, addresses, and phone numbers) and standard experiment summary tables. The archived data are contained within a well-defined structure called data map. Standard words are used for mapping variables and their units within the various data sets. This feature allows global scanning of data sets for specific variables. The data structure is designed so that selected portions may be loaded into the user's data base system or it may be accessed using a custom computer program. An example of a computer code for accessing the data is given.
