8 Figure 17. AIDJEX surface pressure analysis for 1200 GMT, 30 Jan. 1976. Input data locations are denoted by symbols. Each pressure contour is labeled with the last two digits of its value in millibars. 189
FINAL DISPOSITION OF AIDJEX DATA BANK FILES Murray Stateman AIDJEX The termination of the AIDJEX project also signals the end of the AIDJEX data bank. All validated source data have been submitted to iational data banks for permanent retention, together with pertinent documentation. Copies will be distributed from those facilities upon the request of interested scientists. The following information may be useful to them. The data acquired during the AIDJEX main experimenthave been validated, for the most part, by the principal investigators and analysts. Copies of finished data sets had been supplied to the data bank in several forms, such as unformatted binary using Fortran or Extended Fortran and in formatted SCOPE Internal Display code. Each set is in the format preferred by the analysts that created it. The units of common variables also vary with the analysts' preference--for example, time in minutes of the day, dates as year-days or AIDJEX days (starting 1 January 1975), latitude and longitude in decimal degrees, and position in rectangular coordinates originating at the North Pole. Data presented to national data banks whose computer centers are not compatible with the CDC 6400 have been prepared in fixed block record size, external BCD, or even parity. Documentation is included as part of the headers and data records. Narrative descriptions of the data may be included as part of the header. Appendix 1 is a description of the data sets developed and used by the AIDJEX analysts. It had been published in preliminary form in AIDJEX Bulletin No. 36 (May 1977) , pp. 203-210. Appendix 2 is a computerized list of the data transferred to the Environmental Data Service, which maintains the data banks at the National Oceanographic Data Center in Washington, D.C., and the National Climatic Center in Ashevil'le, North Carolina. 190
