Between 1931 and 1961 Canadian forest fire researchers gathered a vast quantity of data on weather, fuel moisture and test fire behavior. The original purpose of the data was primarily for the development of forest fire danger tables. The data was gathered at 11 field stations across Canada. Each station had several sites which were considered representative of the major timber types in the area. Some stations were kept active for several years, while others operated for only one or two seasons. During this period, more than a million observations of various types were recorded. Over the years, much of the information has been analyzed in conjunction with specific projects which centered primarily around fire danger rating. On the other hand, much of the information has never been rigorously scrutinized, due to the sheer enormity of the amount of data. In addition, there is a considerable amount of information available which is usable in present and anticipated fire research studies. With the advent of machine processing, it became possible to handle large quantities of information with much greater ease. For this reason, a project was started in 1960 under the direction of D. G. Fraser to transfer the pertinent information from field notes to punched cards. This has recently been completed, and the result is approximately 200,000 cards of weather, fuel moisture and fire behavior information. Because of the complexity of the data, a 3-card format was used. There was a separate card for weather, fire behavior, and fuel moisture information. Each card was coded with reference information so that all observations made at the same place and time could be matched...In all, ten major and several smaller programs were written for this project, totalllng about 3,060 lines of instructions. Total computer time required for production runs was about 3 and 1/2 hours exclusive of spooling operations which required an additional 8 and 1/2 hours. To simply list all these programs without explanatory notes would require an additional 75 pages. Since these programs are very specialized, interest in them is expected to be very limited. Therefore, anyone requiring information on the individual programs for developing alternate formats and merge operations can obtain it from the Forest Fire Research Institute. The major program titles and a flow chart for the proiect is shown in appendix IV.
