Publikováno v: Remote Sensing, Vol 15, Iss 24, p 5762 (2023)

Geomagnetic storms are one of the leading causes of ionospheric irregularities, depending on their intensity. The 6–10 September 2017 geomagnetic storm, the most severe geomagnetic event of the year, resulted from an X9 solar flare and a subsequent

Prediction of Ionospheric Irregularities using a Combination of Machine Learning Algorithms

Autor: Alireza Atabati, Iraj Jazireeyan, Mahdi Alizadeh, Jakob Flury, Mahmood Pirooznia, Harald Schuh

Ionospheric irregularities can be caused by from sun activity variations, which may cause irregularities in electron density within the ionospheric layer and, subsequently, plasma perturbations. Typical examples of these irregularities are ionospheri

Autor: Mohammad Akbarinasab, Mohammad Akbarnejad Baie, Mahmood Pirooznia

Publikováno v: Journal of Ocean University of China. 19:1255-1264

Internal waves are one of the various phenomena that occur at sea, and they affect acoustic equipment and sea density measurement equipment. In this study, internal waves are simulated using computational fluid dynamics method in the presence of a su

Point wise Determination of Vertical Deformation at southern Coastal Areas of Caspian Sea by Combination of Satellite Altimetry and Tide Gauge Observations

Autor: Mehdi Raoofian Naeeni, Mahmood Pirooznia, Taghi Yousefzadeh

Publikováno v: Annals of Geophysics. 63

In this paper, a combination of satellite altimetry (SA) and tide-gauge (TG) observations is used to determine the pattern of vertical deformation at southern coasts of Caspian Sea. Satellite altimetry measures the variations of sea water surface wit
