Diurnal, seasonal, and solar activity variations of the bottomside electron density profile parameters B 0 and B 1, representing the F2 layer thickness and shape, are studied using a large incoherent scatter radar dataset for Millstone Hill covering the period 1976–2002. These results are compared with the latest IRI model. Our statistical study is characterized by morning and afternoon falls in the diurnal variation of B 0 for seasons other than summer and a ∼15% change in B 1 over a solar cycle, features not fully well represented by the standard IRI model. The standard IRI B 1, however, is very close to observations in terms of the diurnal variation.
