Electron Density Comparison Between IRI 2007 and DEMETER Satellite Data in Solar Minimum Year
Solar activity during 2008 2009 was extremely low among several recent solar cycles, raising an interesting question regarding the temporal and spatial distribution of the plasma parameters in ionosphere during this time period. This study analyzes the electron density (Ne) data recorded by the DEMETER satellite at the height of 670 km and compares it with the International Reference Ionosphere...
متن کاملThailand low and equatorial F2-layer peak electron density and comparison with IRI-2007 model
Ionosonde measurements obtained at two Thailand ionospheric stations, namely Chumphon (10.72◦N, 99.37◦E, dip 3.0◦N) and Chiang Mai (18.76◦N, 98.93◦E, dip 12.7◦N) are used to examine the variation of the F2-layer peak electron density (Nm F2) which is derived from the F2-layer critical frequency, fo F2. Measured data from September 2004 to August 2005 (a period of low solar activity) are analyze...
متن کاملComparative study of foF2 measurements with IRI-2007 model predictions during extended solar minimum
The unusually deep and extended solar minimum of cycle 23/24 made it very difficult to predict the solar indices 1 or 2 years into the future. Most of the predictions were proven wrong by the actual observed indices. IRI gets its solar, magnetic, and ionospheric indices from an indices file that is updated twice a year. In recent years, due to the unusual solar minimum, predictions had to be co...
متن کاملElectron density in the F region derived from GPS/MET radio occultation data and comparison with IRI
The inversion of electron density from total electron content (TEC) measurements of GPS radio occultation is investigated by means of simulated data from the International Reference Ionosphere IRI-2001 and observations by the GPS/MET satellite experiment. In both cases a meridional slice of electron density is derived for northern summer solstice June/July 1995 from the midnight to the noon sec...
