The midnight temperature maximum from Arecibo incoherent scatter radar ion temperature measurements
The midnight temperature maximum (MTM) is studied using ion temperature data from the incoherent scatter radar at the Arecibo Observatory (18.31N, 66.21W). The MTM is characterized by fitting the radar data with a function that takes into account diurnal, semidiurnal and terdiurnal components. Under the hypothesis that the MTM is related to the amplification of the terdiurnal wave, a Gaussian a...
متن کاملVariations 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...
متن کاملIonospheric climatology and variability from long-term and multiple incoherent scatter radar observations: variability
Long-term incoherent scatter radar (ISR) observations are used to study ionospheric variability for two midlatitude sites, Millstone Hill and St. Santin. This work is based on our prior efforts which resulted in an empirical model system, ISR Ionospheric Model (ISRIM), of climatology (and now variability) of the ionosphere. We assume that the variability can be expressed in three terms, the bac...
متن کاملHigh latitude convection based on long-term incoherent scatter radar observations in North America
High latitude ionospheric convection patterns and models are obtained based on a composite analysis of incoherent scatter radar (ISR) observations in the North America sector at Millstone Hill and Sondrestrom (MHS). These observations span a combined latitude range of 55 pLp82 over time periods starting from 1978 for Millstone Hill and from 1995 for Sondrestrom. These models, regional to the Am...
متن کاملEmpirically modeling ionospheric electron density variations using F107, E107 and MgII indices based on long-term incoherent scatter radar observations over Millstone Hill
Each of three solar flux indices, F107, E107, and MgII core-to-wing, has been tested as a solar activity proxy to model empirically electron density Ne measurements made by an incoherent scatter radar during the period of 1976-2001 over the height span of 1501000km at Millstone Hill. It is found that deviations of model values given by the three indices to the data are practically the same, reg...
