Characteristics of ionospheric scintillation climatology over Indian low-latitude region during the 24th solar maximum period

Systematic study of ionospheric scintillation over the indian low-latitudes during low solar activity conditions

“…During the equinoctial months, the ROTI values for all the satellites of both the constellations varied between 0.5 to 1 for most of the days. The seasonal and solar activity dependence of the scintillation occurrence as observed using NavIC over these regions is in agreement with that of previous studies (Sousasantos et al, 2018;Sahithi et al, 2019;Zou and Wang, 2009;Liu et al, 2015a).…”

Climatology of Ionospheric Amplitude Scintillation on GNSS Signals at South American Sector During Solar Cycle 24

“…The presence of post-midnight scintillations is also important and reflects the presence of post-midnight EPBs that are of 2 kinds: (i) long-living EPBs generated at post-sunset hours and migrating in the field of view of the receiver and (ii) freshly generated EPBs. The results presented here agree with results from previous investigations, such asSpogli et al (2013a),Spogli et al (2013b), andBougard et al (2013) over SA,Tilahun (2020) over Africa,Sahithi et al (2019) over Indian sub-continent, andLi et al (2020) over Southern China.…”

“…Over the Indian sub-continent, Goswami et al (2017) found intense scintillations at the northern anomaly crest region of Calcutta during the equinoxes and Joshi et al (2019) found that scintillation variability in the autumnal equinox was highly correlated with the periodic geomagnetic activity. Sahithi et al (2019) investigated the climatology of scintillations over India at stations located around the crest and trough regions of the EIA, identifying that the probability of scintillations is higher during March equinox and December solstice, and lowest during June solstice, maximizing in the post-sunset hours.…”
