چکیده انگلیسی
Of unique relevance to IRI is that these extended observations have enabled the ionospheric morphology to be distinguished between quiet and disturbed geomagnetic conditions. During the IPY year, 1 March 2007 - 29 February 2008, about 50 solar wind Corotating Interaction Regions (CIRs) impacted geospace. Each CIR has a two to five day geomagnetic disturbance that is observed in the ESR and PFISR observations. Hence, this data set also enables the quiet-background ionospheric climatology to be established as a function of season and local time. These two separate climatologies for the ion temperature at an altitude of 300Â km are presented and compared with IRI ion temperatures. The IRI ion temperatures are about 200-300Â K hotter than the observed values. However, the MSIS neutral temperature at 300Â km compares favorably with the quiet-background in temperature, both in magnitude and climatology.
