Abstract Correlation between rainfall and short period GPS-TEC (total electron content) variations are investigated by using the precipitation data obtained on ground estimated from satellite observations (JAXA/GSMaP) as a proxy of lower atmospheric wave activity. The at tropical station, PHIM, in Phimai, Thailand, for 2014–2020, mid-latitude NAKG, Tokara Nakanoshima Island, Japan, 2017–2019, e...
A total solar eclipse occurred at the ascending node of Moon's orbit on 2 July 2019, with an magnitude 1.0459. The totality was visible from southern Pacific Ocean east New Zealand to Coquimbo Region (Chile) and Central Argentina sunset, maximum 4 min 32 s Ocean. recent Great American Eclipse, 21 August 2017, clearly showed that ionosphere is strongly affected by totality. In order explore iono...
We describe a method for removing ionospheric effects from single-frequency radio data a posteriori. This method is based on a theoretical climatological model developed by the USAF, which returns ne(~r, t) along the line of sight to the source. Together with a model of B⊕, ionospheric delay and Faraday rotation values ensue. If contemporaneous ionospheric data — GPS TEC observations or ionoson...
Interplanetary shocks can cause violent disturbances in near-earth space. In this paper, we use high time-resolution (1 s) data from ground-based global position system (GPS) receivers to analyze the perturbations of ionosphere total electron content (TEC) when an interplanetary shock impacted Earth’s magnetosphere on March 17, 2015. We found that after arrived at Earth, ...
