The passage of the 100km wide, super-sonic lunar shadow offered the opportunity to examine the changes in electron densities, radio absorption, neutral wind patterns and the possible generation of waves in the layers of the ionosphere. All these for an event for which the cause of the disturbance can be calculated with accuracy. Reported here are the results from the vertical ionosondes located under the path of totality and in the partial eclipse region and dual frequency GPS TEC measurements. The ionosondes showed that even in the partial shadow the peak electron densities of the F & E ionospheric layers decreased by as much as 20–35%. The TEC measurements showed that the vertical equivalent line integrated electron density dropped by 15% at the 97% partial eclipse north of the path of totality. The consequences of these observations are discussed in relation to making model predictions.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 5","pages":"Pages 373-377"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)00016-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80440822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diurnal and seasonal variations of the ionospheric foF2 and M(3000)F2 parameters are represented by a modified version of the regional model ISIRM adjusted to the past measured data. An autoregressive extrapolation of the data from the past month enables the 15-day-ahead forecast of the quiet ionospheric distribution to be performed. In addition, the short-term variations due to geomagnetic activity are defined as a plane surface superimposed on the quiet distribution. This correction is obtained by two plane characteristics as functions of the geomagnetic three-hour Kp index. In this way the 24-hour forecast can be obtain during quiet as well as disturbed ionospheric conditions. The corresponding EIFM software provides a variety of options to perform the short-term forecast depending on availability of the measured ionospheric data and predicted Kp values.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 5","pages":"Pages 347-351"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)00011-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85262795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measuring station has been installed at Tito site on the Southern Apennine chain, one of the most seismic active areas of the Mediterranean region; it combines new technologies for the data acquisition with a robust statistical technique to discriminate anomalous fluctuations from background noise in the recorded signals. The completely automatic station is equipped with sensors able to detect self-potential signals (16 channels, A/D 24 bit, sampling rate of 0.25Hz) and a 1Hz three directional seismometer connected to an acquisition unit having a dynamics of 133 dB. After a preliminary filtering procedure, mainly devoted to remove all the influences due to meteo-climatic parameters and/or cultural electrical noise, a software developed ad hoc to study the possible correlation between anomalous patterns in electrical signals and local microseismic activity was employed. In particular, the instrumental features of the new station allow us to compare the fluctuations of electrical signal, detected at short temporal scales, with seismic events with low magnitude (M<3), that are not revealed by the national seismometric network (National Institute of Geophysics). The analysis of the first results obtained during the 1999 confirms us that the station could be largely used in a geophysical monitoring network operating in seismic active areas.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 10","pages":"Pages 787-791"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)95026-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77052390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using permanent operating GPS ground station networks (e.g. that from IGS) the derived TEC maps may contribute to monitor the actual development of large scale structures in electron content and their dynamics during ionospheric perturbations (e.g.www.kn.nz.dlr.de/ → Ionosphere Impact → Storm). Based on GPS measurements at European IGS ground stations and subsequent TEC estimations and mapping, both individual as well as common features of ionospheric storms shall be discussed for the European ionosphere. The paper demonstrates the power of this new GPS tool to detect and to study the dynamics of large-scale spatial structures (e.g. ionospheric response of solar eclipse on 11 August 1999). Detected TEC-perturbations are closely related to space weather characterizing quantities such as solar radio emission, solar wind and geomagnetic activity indices. Due to close relationships between TEC and space weather parameters a permanent space weather monitoring can help to control the ionospheric impact on operational navigation satellite systems.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 8","pages":"Pages 609-613"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)00056-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72217831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
