Scientific paper

A partial reflection radiowave system (2.2 MHz) has been used at Saskatoon, Canada to obtain electron densities (65-85 km) by the differential absorption experiment, and winds (52-118 km) by the spaced antenna drifts experiment. These data have been compared during the winter (December-March) of 1974/75, 11 selected days during January and February of 1976, and during 10 days in each of the four seasons of 1976. There is consistent evidence for a correspondence between increasing ionization and decreasing northward or increasing southward winds, during winter months. This is consistent with the hypothesis that nitric oxide, created during magnetic storms by the associated auroral activity, contributes to electron density variability by way of circulation changes and atmospheric waves. It has not been possible to distinguish between a latitude gradient of NO or isolated accumulations of this minor constituent.
