Global model comparison with Millstone Hill during September 2005

Comparison of Simultaneous Chatanika and Millstone Hill Observations with Ionospheric Model Predictions

Ionospheric plasma temperatures during 1976 – 2001 over Millstone Hill

Incoherent scatter measurements have been made since the 1960s over Millstone Hill. Zenith antenna data since 1976 and steerable antenna data since 1980 are now available through the WWW-based Madrigal database system. By analyzing this large volume of data in a systematic way, this paper provides an updated climatology of the ionospheric temperature over Millstone Hill, including diurnal varia...

Ionospheric Backscatter Observations at Millstone Hill

Studies of the electron-density, e Iectron and ion temperatures in the F-region were mode by means of ground-based radar observations O? the M; I Istone Hi I I Radar Observato~. A 70-meter parabol i. ontenna directed vertical Iy and o 2. 5-Mw pulse radar operating at 440 Mcps were employed for these measurements which were conducted for periods of 30 hours at approximately weekly intervals thro...

Comparison of model electron densities and temperatures with Millstone Hill observations during undisturbed periods and the geomagnetic storms of 16–23 March and 6–12 April 1990

Measurements of F-region electron density and temperature at Millstone Hill are compared with results from the IZMIRAN time-dependent mathematical model of the Earth’s ionosphere and plasmasphere during the periods 16–23 March and 6–12 April 1990. Each of these two periods included geomagnetically quiet intervals followed by major storms. Satisfactory agreement between the model and the data is...

Long-term temperature trends in the ionosphere above Millstone Hill

[1] Increasing concentrations of greenhouse gases are expected on theoretical grounds to lead to a cooling of the upper atmosphere. Due to the close thermal coupling of the neutral and ionized components of the upper atmosphere the effects of this cooling are also expected to be seen in the ionospheric ion temperature. Long-term satellite observations of neutral density show a trend consistent ...
