Abstract

Monthly median maps of ionospheric foF2 parameter show considerable discrepancies between the actual measurements and the values detected from the maps. Different instantaneous mapping techniques applied to randomly sparsed measurements give better agreement than monthly median maps. The objective of this paper is to present the PLES instantaneous mapping model for foF2 and M(3000)F2 that has been recommended as the best achievement of the COST 251 European Action. The method combines monthly median maps of ionospheric characteristic and a set of screen points consisting of measurements for a single moment of time as well as single station long-term models.

    For the purpose of the present study, the source GIM-TEC maps are converted to geomagnetic coordinates binned in −87.5° N to 87.5° N in steps of 2.5° in geomagnetic latitudes, and 0° E to 360° E in steps of 5° in geomagnetic longitude using the International Geomagnetic Reference Field (IGRF) model. The second set of foF2 maps is obtained using the PRIME251 mapping procedure (PRIME-foF2) provided by Space Research Center of Poland (Stanislawska et al., 1996, 2000). These maps are produced with Kriging technique by assimilation of the ionosonde foF2 data into IRI model adjusted to the ITU-R (CCIR, 1983) median foF2 from 1999 to 2006.

    This causes significant errors in the positioning and navigation system (Bagiya et al., 2009). Many empirical models have been developed to predict the variability of the ionosphere with great efficiency in various regions throughout the world, such as the Bent model (Bent et al., 1975), Global Ionospheric Maps (GIMs) (Stanislawska et al., 2000; Wielgosz et al., 2003) and the Klobuchar model (Klobuchar, 1996). Furthermore, many alternative techniques to traditional methods have been developed for the purpose of ionospheric predictions, such as the Autoregressive Moving Average (ARMA) method and auto-covariance, which have been used to model the TEC time series over different European stations.

    Fig. 2a and b represent foF2 maps over Australia before the earthquake at 09 h UT and 10 h UT after EQ, respectively. W-index maps for the same hours are provided in Fig. 2c and d. Data of 12 ionosondes listed in lines 3 to 14 of Table 1 (Fig. 2a–d, crosses) are assimilated by the instantaneous foF2 mapping procedure (Stanislawska et al., 2000) for the day of earthquake and 27 preceding days. The quiet reference median foF2 map is derived from the instant maps for −27 preceding days to serve for W-index map production (Gulyaeva et al., 2008).

    One method is the KG algorithm that is a widely used interpolation originally developed for geology (Krige, 1951; Matheron, 1963). Recently, various studies (Stanislawska et al., 1996, 2000; Wielgosz et al., 2003; Wang et al., 2006; Sayin et al., 2008; Liu et al., 2008) used the KG algorithm to reconstruct maps of ionospheric parameters. The KG algorithm behaves more accurately when larger numbers of recorded data are utilized.

    The data sets have been checked for their consistency with model adopted, otherwise in a case of controversial F region peak records and TECgps input these data have been rejected from the analysis. Partially missed observations by ionosonde during the storm time due to ionospheric absorbtion, sporadic E layer appearance, spread-F phenomena and other physical or technical reasons have been restored with mapping technique (Stanislawska et al., 2000). Selection of the ionospheric quiet days (Q), positively (D+) and negatively (D−) disturbed days has been made with ranking bias (observed minus monthly average) for the daily mean, daily maximum, and daily rate of change of the hourly values of peak electron density NmF2 (Gulyaeva and Makarova, 1998).
