A study of Traveling Ionospheric Disturbances and Atmospheric Gravity Waves using EISCAT Svalbard Radar IPY-data
We present a statistical study of Traveling Ionospheric Disturbances (TIDs) as observed by the EISCAT Svalbard Radar (ESR) during the continuous IPY-run (March 2007–February 2008) with field-aligned measurements. We have developed a semi-automatic routine for searching and extracting Atmospheric Gravity Wave (AGW) activity. The collected data shows that AGW-TID signatures are common in the high...
متن کاملEISCAT verification in the development of ionospheric tomography
This paper highlights the important role played by the EISCAT radar for verification in the development of tomographic techniques to produce images of ionospheric electron density. A brief review is given of some of the stages in the application of tomographic reconstruction techniques to the ionosphere. Results are presented to illustrate the effectiveness of the method in imaging ionospheric ...
متن کاملGlobal Assimilative Ionospheric Model
The long-term goal of our research is to develop a reliable and accurate global ionospheric weather monitoring and forecast system which can serve as a prototype for an operational system. To achieve this goal, we are developing and validating advanced data assimilation techniques to analyze diverse sources of ionospheric measurements. The assimilation of ionospheric measurements into mature fi...
متن کاملIranian Permanent GPS Network Receivers Differential Code Biases Estimation Using Global Ionospheric Maps
Measurements of the dual frequency Global Positioning System (GPS) receivers can be used to calculate the electron density and the total electron content (TEC) of the ionosphere layer of the Earth atmosphere. TEC is a key parameter for investigating the ongoing spatial and temporal physical process of the ionosphere. For accurate estimation of TEC from GPS measurements, GPS satellites and GPS r...
متن کاملEISCAT Svalbard radar observations of ionospheric signatures of magnetopause reconnection during a changing IMF BZ polarity
Observations by the EISCAT Svalbard radar are presented that show the response of the spatial structure of the ionosphere in the dayside cusp region to a rotational trend in the IMF clock angle. Over a period of one hour, the clock angle increased from about 45 to some 150, moving the likely location of the magnetopause reconnection site from the high-latitude lobe to near the equatorial plane....
