  • Co-ordinated observations of VHF scintillations in India during February-March 1993 
    Kumar, Sushil; Gwal, A.K.; Rao, P.V.S. Rama; Jaychandran, P.T.; Prasad, D.S.V.V.D.; Singh, R.P.; Singh, U.P.; Dasgupta, A.; Basu, K.; Sethuraman, R.; Pathan, B.M.; Rao, D.R.K.; Banola, S.; Kesava Rao, P.S.; Naidu, Appala; Tyagi, T.R.; Vijaykumar, P.N.; Chandra, H.; Vyas, G.D.; Singh, Birbal; Chauhan, Pawan; Iyer, K.N.; Pathak, K.N.; Shalgaonkar, C.S.; Vyas, B.M.; Rastogi, R.G. (2000)
    The VHF scintillation observations made at a chain of stations in India during February-March 1993 under AICPITS (third campaign), using the 244 MHz radio beacon from FLEETSAT, and analysed jointly by all participating ...
  • Equatorial spread F: Statistical comparison between ionosonde and scintillation observations and longitude dependence 
    Iyer, K.N.; Jivani, M.N.; Pathan, B.M.; Sharma, S.; Chandra, H.; Abdu, M.A. (2003)
    Spread F on ionograms and scintillations of trans-ionospheric signals arise from unstable structure of the ionospheric F-region occurring predominantly by night. The two techniques were applied to two pairs of sites in ...
  • Low-latitude ionospheric-thermospheric response to storm time electrodynamical coupling between high and low latitudes 
    Bagiya, Mala S.; Iyer, K.N.; Joshi, H.P.; Thampi, Smitha V.; Tsugawa, Takuya; Ravindran, Sudha; Sridharan, R.; Pathan, B.M. (2011)
    Using multi-instrumental and multistation data, we present low-latitude ionospheric-thermospheric behavior during the geomagnetic storm of 15 May 2005. The diurnal pattern of total electron content (TEC) at a chain of ...
  • A model of equatorial and low latitude VHF scintillation in India 
    Iyer, K.N.; Souza, J.R.; Pathan, B.M.; Jivani, M.N.; Joshi, H.P.; Abdu, M.A. (2006)
    Using the observed VHF scintillations at equatorial and anomaly crest stations in India during the years 1987-1989, an empirical model is developed. The model employs the cubic spline technique to reproduce the variation ...
  • Some features of plasma bubble induced scintillations during the AICPITS campaigns of 1991 
    Vijayakumar, P.N.; Tyagi, T.R.; Singh, Lakha; Chandra, H.; Vyas, G.D.; Rao, D.R.K.; Pathan, B.M.; Iyer, A.; Ramsekaran, B.; Naidu, A.; Sadique, S.M.; Iyer, K.N.; Pathak, K.N.; Gwal, A.K.; Kumar, Sushil; Singh, R.P.; Singh, U.P.; Singh, Birbal; Kumar, Pawan; Navneeth, G.N.; Koparkar, P.V.S.; Ramarao, P.V.S.; Jaychandran, P.T.; Sriram, P.; Sethuraman, R.; Dasgupta, A.; Basu, K.; Rastogi, R.G. (2007)
    The VHF scintillations were recorded at a chain of low-latitude stations in India as part of the All India Coordinated Programme of Ionospheric and Thermospheric Studies (AICPITS), using the 244 MHz radio beacon from the ...
  • Study Of Mass Distribution Of Near Surface Aerosols At Maitri, Antarctica 
    Ranjan, Ritweej Rajeev; Ghadai, Narayan Chandra; Iyer, K.N.; Joshi, H.P.; Dhar, Ajay; Rawat, Rahul; Pathan, B.M. (International Journal of Scientific Research and Engineering Studies, V. 2, no. 6, 2015, 2015-06)
  • TEC variations during low solar activity period (2005–2007) near the Equatorial Ionospheric Anomaly Crest region in India 
    Bagiya, Mala S.; Joshi, H.P.; Iyer, K.N.; Aggarwal, Malini; Ravindran, S.; Pathan, B.M. (2009)
    The dual frequency signals from the GPS satellites recorded at Rajkot (22.29° N, 70.74° E, Geographic, 14.03° N Geomagnetic) near the Equatorial ionization anomaly crest in India have been analyzed to study the ionospheric ...
