Incoherent Scatter Measurements of F-region Density, Temperatures, and Vertical Velocity at Millstone Hill

A statistical study of ionospheric profile parameters derived from Millstone Hill incoherent scatter radar measurements

[1] Diurnal, seasonal, and solar activity variations of the bottomside electron density profile parameters B0 and B1, 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...

Variations of electron density based on long-term incoherent scatter radar and ionosonde measurements over Millstone Hill

[1] Measurements from the incoherent scatter radar (ISR) and ionosonde over Millstone Hill (42.6 N, 288.5 E) are analyzed to explore ionospheric temporal variations. The F2 layer peak density NmF2, peak height hmF2, and scale height H are derived from a Chapman a layer fitting to observed ISR electron density profiles. Diurnal, seasonal, and solar activity variations of the ionospheric characte...

Solar EUV flux, exospheric temperature and thermospheric wind inferred from incoherent scatter measurements of the electron density profile at Millstone Hill and Shigaraki

[1] We explore a method for inferring solar EUV flux, atmospheric composition and wind using ionospheric electron density Ne profile measurements. Incoherent scatter radar data from Millstone Hill and Shigaraki measured on October 5, 1989 are assimilated into a theoretical model whose driving forces, solar EUV flux, exosphere temperature Tex, and meridional wind, are adjustable. Adjustments are...
