Abstract : From 3 to 20 June 1972 the airborne ionospheric laboratory was stationed in RAF Mildenhall, England, for the purpose of obtaining realistic ionization cross-sections suitable for assessing HF propagation conditions in the Arctic. A number of quasi-instantaneous cross-sections for various hours during local night of five different days were produced, however limited to low magnetic activity, except for one PCA event, and limited to the area north of England. The results provide a three dimensional representation of the ionosphere along a 7 degree wide azimuth range. (Author)
