Marine surface and upper air observations recovered from microfilm copies of cards at NCDC. In the 1960's-1970's NCDC stored images of selected 80-character punched card decks on microfilm (16mm) using a device known as FOSDIC (Film Optical Sensing Device for Input to Computer). FOSDIC was also used to recall the images back to digital records.
