Abstract:

A first-order estimate of the shape of the electron density profile, Nsubeh, is given by the ratio of the profiles total electron content TEC to its peak density Nmax. Applications to transionospheric and hf supported propagation can be aided by models of this quantity, tab and thus the BUAFGL slab thickness model has been developed to describe the mean variations of slab thickness. In this paper addresses the issue of how geomagnetic disturbances affect tab at mid-latitudes, making use of a database of two solar cycles of observations from Hamilton Ma and Wallops Island Va. These results are compared with those deduced from an Italian station pairFlorence and Rome.
