Abstract
IN connexion with the International Polar Year 1932-33, a series of wireless observations has been made at Tromsô (lat. 690 39.8′ N.; long. 180 56.9′ E.) in Norway. The fundamental aim of the work may be briefly stated to be the investigation of ionospheric conditions in high latitudes and of the relation between these conditions and magnetic and auroral disturbance. The observations may be regarded as an extension of the work previously conducted on similar lines in south-east England by British workers under the auspices of the Radio Research Board of the Department of Scientific and Industrial Research. The expedition to Norway for the thirteen months of the International Polar Year has been sent out by that Department and contributions towards the total cost have been made by the British National Committee for the Second Polar Year and by the Council of the Institution of Electrical Engineers. Special facilities and privileges have been accorded to the expedition by the Norwegian Government and by the Norwegian Committee for Cosmic Physics, while the latter body invited us to make our principal receiving station at the Auroral Observatory, Tromsô, where laboratory and living accommodation has been provided. The sending station was erected at Simavik, about 20 km. north of Tromsô, on the island of Ringvassôy. The choice of these sites and many other helpful arrangements were made for us by Mr. R. A. Watson Watt, who visited Tromsô in March, 1932. It has proved a great advantage to have the receiving site at the Observatory at Tromsô, where the magnetic records have been immediately available and where Director Harang and Mr. E. Tônsberg have given us every other possible assistance. A member of our party, Mr. W. C. Brown, has been in charge of the sending station at Simavik during the whole period of the observations.
