The phrase "analysis of the topside" is correct and usable in written English.
It can be used in contexts related to engineering, geology, or any field where the term "topside" refers to the upper part of a structure or surface that is being analyzed.
Example: "The analysis of the topside revealed several structural weaknesses that need to be addressed before proceeding with the project."
Alternatives: "examination of the upper section" or "assessment of the surface area".
First results from the analysis of the topside plasma scale height's temporal and spatial variations are also provided.
Later, Zakharenkova and Astafyeva (2015) proposed an "additional" use of the precise orbit determination (POD) GPS measurements onboard a single LEO satellite, CHAMP, for multi-instrumental analysis of the topside ionospheric irregularities.
Fig. 4 Linear regression analysis of the topside vertical ion drift velocities between 1800 and 1900 LT with the ESF irregularity occurrence rates measured by the ROCSAT-1 satellite.
This analysis suggests that at least part of the topside of the normal sodium layer originates in a source that also gives rise to sporadic layers, which would occur when the source itself becomes layered.
The present paper focuses on the comparative analysis of the plasma density irregularities detected in the topside ionosphere by two independent techniques GPS and Langmuir probe (LP) measurements.
Results from the analysis show that load directions and structural configuration play a prominent role in the response of the topside.
The objective of this paper was to introduce more advanced and practical procedures for fire load application methods considering the effects of Passive fire protection (PFP) with the motivation to nonlinear structural consequence analysis of FPSO topsides structures under fire load.
Our analysis focused on topics that had not previously been addressed using these profiles, namely the effects of a dust storm on the topside ionosphere, the morphology of the topside ionosphere, the behavior of the M1 layer, and possible meteoric layers.
A new empirical model of the topside ionospheric density was developed to describe the measured topside profile accurately.
Mariner 9 observations of the topside ionosphere differ from comparable Mars Express observations.
In particular, the nonlinearity combined with an inverse response behavior makes the control of the topside pressure more difficult.
