Variability of Ionosphere Over Indian Longitudes to a Variety of Space Weather Events During December 2006
Published 2023-11-01“…On the next day, a stream of fast solar wind hits the magnetosphere, causing a HILDCAA (High Intensity Long Duration Continuous Auroral Activity) preceded by moderate geomagnetic storm. The origin and characteristics of a positive ionospheric storm which occurred over Tirunelveli (TIR, geomagnetic latitude: −0.18°N) in the recovery phase of storm due to simultaneous presence of enhanced O/N2 and WEJ or weakened EEJ during the HILDCAA (7th and 8th of December) is investigated. …”

Verification of the cell azimuth based on clustering of sampling point and division of switching quadrant
Published 2017-05-01“…Engineering data mainly depends on manual maintenance,and the poor accuracy restricts the development of network planning optimization.Aiming at the cell azimuth in engineering data,the simulated azimuth of the cor-responding cell was calculated by using the sampling point clustering algorithm and the switching quadrant partition-ing algorithm by collecting the measurement report data and the switching statistical data of the network management system.By comparing the simulated azimuth angle and the actual azimuth angle,the existing problems were found,which could be used to guide the data updating and engineering rectification.Through the actual verification of the current network,the research method has achieved good application effect.Similarly,the study can be applied to the latitude and longitude of engineering data,which has a strong reference value.…”
