Thailand 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 کاملVariability of F2-layer peak characteristics at low latitude in Argentina for high and low solar activity and comparison with the IRI-2016 model
This work presents the study of the variability of foF2 and hmF2 at a low latitude station in South America (Tucumán, 26.9°S, 294.6°E; magnetic latitude 15.5°S, Argentina). Ground based ionosonde measurements obtained during different seasonal and solar activity conditions (a year of low solar activity, 2009 and one of high solar activity, 2016) are considered in order to compare the ionospheri...
متن کاملValidation of the IRI-2012 model with GPS-based ground observation over a low-latitude Singapore station
The ionospheric total electron content (TEC) in the low-latitude Singapore region (geographic latitude 01.37° N, longitude, 103.67° E, geomagnetic latitude 8.5° S) for 2010 to 2011 was retrieved using the data from global positioning system (GPS)-based measurements. The observed TEC from GPS is compared with those derived from the latest International Reference Ionosphere (IRI)-2012 model with ...
متن کاملComparison of COSMIC measurements with the IRI-2007 model over the eastern Mediterranean region
This paper presents a comparison of the International Reference Ionosphere (IRI-2007) model over the eastern Mediterranean region with peak ionospheric characteristics (foF2-hmF2) and electron density profiles measured by FORMOSAT-3/COSMIC satellites in terms of GPS radio occultation technique and the Cyprus digisonde. In the absence of systematic ionosonde measurements over this area, COSMIC m...
متن کاملIri Task Force Activity at Ictp: Proposed Ments for the Iri Region below the F Peak Improve-
The Aeronomy and Radiopropagation Laboratory of the International Center for Theoretical Physics (ICTP) in Trieste, Italy has hosted special IRI Task Force Activities (‘IFAs) annually since 1994. This article reviews the format and results of the 1994, 1995, and 1996 TFAs. The prime focus of these TFAs has been the Fl region and the bottomside F2 region. Each meeting has tackled a specific subs...
