Extremely Low Frequency (ELF) and Very Low Frequency (VLF) emissions are one of them and are believed to have origin in the ionosphere-magnetosphere coupled system and may be due to plasma instabilities or in-situ electromagnetic radiation from high-energy particles. The propagation of these emissions in the ionized regions (ionosphere and magnetosphere) provides invaluable information regarding the physical structure and characteristics of these regions. In this paper we have presented the observed hiss with periodic structures at Indian Base Station ?MAITRI?, Antarctica during the XXIV Indian Antarctic Expedition. The unique location of MAITRI Indian Research Base Station at Antarctica near auroral latitudes makes it important for monitoring Extremely Low Frequency (ELF) - Very Low Frequency (VLF) wave phenomena. It is well known that the auroral oval is a region of closed magnetic field lines mapping through the plasma sheet. In characterizing the generation of ELF-VLF waves and their subsequent energization of auroral ions, a larger scale energy transfer process may be observed due to the energetic auroral electrons, emit intense emissions. Such a link in the auroral plasma environment would fill an important gap in the understanding of how ionospheric ions are transported into the magnetosphere. The wave and wave particle interactions occurring in the magnetosphere generates wide variety of emissions in the ELF-VLF range. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. Shailendra Saini climatologyMeteorologyAtmosphere 20.0 140.0 -90.0 30.0 2004-01-01 2005-12-31 Earth Science-Atmosphere Theme Maitri Antarctic Place Study of ELF-VLF Emission and Tweek Atmospherics Observed at Maitri Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncpor.res.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF786254639&userType=user&freeTextValue=Study+of+ELF-VLF+Emission+and+Tweek+Atmospherics+Observed+at+%3FMaitri%3F.
