Study on the Venusian Atmospheric Thermal Structure: A Comparative Analysis between VEX/Akatsuki and Venus-GRAM/VCD
Soumyaneal Banerjee, R. K. Choudhary, Keshav R. Tripathi +5
We investigate the thermal structure of the Venusian middle atmosphere between 45 and 80 km using radio occultation (RO) measurements from Venus Express and Akatsuki spanning 2006-…
A study on the contribution of the interplanetary medium in radio occultation experiments
Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +4
Irregularities in electron density within the interplanetary medium (IPM) can cause fluctuations in the Doppler frequency of spacecraft radio signals. The amplitude of these fluctu…
A generalized method for estimating solar wind speeds and densities using spectral broadening for a Kolmogorov turbulence spectrum
Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +3
We present a unified method to derive both solar wind velocities and coronal electron densities in the near-Sun corona using Doppler spectral broadening of spacecraft radio signals…
A turbulence index independent framework for deriving solar wind speed and coronal electron density from radio spectral broadening
Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +3
We present a turbulence index independent framework for simultaneously deriving solar wind velocity and coronal electron density in the near-Sun region using the spectral broadenin…
On the estimation of Sulfuric Acid Vapor concentrations below the Venus cloud deck using the Akatsuki Radio Science Experiment
S. Banerjee, R. K. Choudhary, K. R. Tripathi +2
We report new constraints on the vertical distribution of sulfuric acid vapor in the Venusian atmosphere, derived from a refined analysis of radio occultation (RO) data. The method…
On the estimation of solar wind velocity under varying solar activity conditions using Akatsuki measurements
Keshav Aggarwal, R. K. Choudhary, Abhirup Datta +1
We present an analysis of solar wind dynamics based on Doppler spectral width measurements of X-band radio signals from the Japanese Akatsuki spacecraft. The dataset includes two s…
