Context

Country: Canada
State/Province: Unknown
Period: 1958+
Canada: THIS ARCHIVAL MATERIAL IS THE PRODUCT OF CANADIAN UPPER ATMOSPHERIC RESEARCH. SUCH STUDIES ARE OF PARTICULAR INTEREST IN CANADA BECAUSE OF THIS COUNTRY'S DEPENDENCE ON THE IONOSPHERE TO PROPAGATE RADIO WAVES FOR COMMUNICATIONS, A MATTER OF CONSIDERABLE IMPORTANCE IN A NATION OF CANADA'S SIZE.
Function: ARCHIVAL TAPES CONTAINING DATA ON THE UPPER ATMOSPHERE. THE ELECTROMAGNETIC SIGNALS WERE RECORDED ON TAPE TO BE PLAYED BACK AS SOUND RECORDINGS; SCIENTISTS INTERPRETED THE SIGNALS BY ANALYSING VARIATIONS OF FREQUENCY WITH TIME.
Technical: THESE TAPES ARE EXAMPLES OF DATA OBTAINED THROUGH THE EXPLORATION OF THE IONOSPERE FROM THE GROUND BY MEANS OF RADIO RESEARCH TECHNIQUES. THIS APPROACH WAS SOON SUPERCEDED BY STUDIES CONDUCTED VIA SATELLITES IN EARTH ORBIT (SEE 940006).
Area Notes: Unknown
