Ionosphere Definition and 20 Threads

Hello everyone! I'm currently an Aerospace major student entering my third year of college, studying in northern Mexico. After enrolling in a summer school by Mexico's national space weather lab, I have been offered an opportunity to participate in the development of an ionosonde antenna in my...

Hi, what causes the production of electrons in the ionosphere? The electron density results for photon ionization. How is there a depletion in electron density and why is it characterized by the following recombination reaction: O^+ + N_2 -> NO^+ +N ?

Hello all It's been a while ,as I read the almost daily news on climate change , some question come up to my mind , dose the ionosphere has any effect on climate change , as we all know now the Earth magnetic field is weakening ,and the temperature is rising ,dose this two variables related to...

Hi guys, Disclaimer: not a physicist (I wish I was that brainy) Quick question regarding a speculative architecture project I am undertaking; In the completely hypothetical event of a huge, otherworldly solar flare super-charging the Earth's ionosphere beyond anything we have ever recorded...

The region of the ionosphere with highest electron density is where molecules and atoms are being ionized by photons radiated directly from the Sun. Is the rest of the ionosphere staying ionized mainly due to interactions with the free electrons and recombination photons that spread out from...

What is the reason for this? Is it because of the Earth's rotation?

Is there an instrument or has there been an instrument that measures electron density in the ionosphere (50km - 450km)?

I'm studying Modelling of Low Latitude Ionospheric Irregularities by A. K. Singh et al., at a research level. I really need help on the explanation of this paper as several messages to the authors has left no replies. Link to the paper...

In 'Introduction to Mechanics' by Kleppner and Kolenkow...motion of ionospheric electron under non-uniform acceleration is x = (a0/w)t - (a0/w^2)sin wt...my question is when there is non-uniform acceleration, it makes sense to have sinusoidal part in the motion...but how come there is uniform...

Hi all, I am trying to understand about collision frequency that happened in ionosphere layer. In D region, below 90 km [Wait and Spies 1964] the ionospheric electron-neutral collision frequency given as v(h) = 1.816x10e11 exp(-0.15h) I just wondering, to who ever really expert in...

Hi, Reading through an Introductory Mechanics Textbook, I don't understand a part of an example on Nonuniform Acceleration - The effect of a Radio Wave on an Ionosphere Electron. I've attached the link. Can someone please explain how: a0 = (-eE0/m)sinωt By my reasoning, since...

Homework Statement I have these equations: ga = exp(-σ^{R}Δt/ε_{0}*ε^{R}_{r}) Homework Equations σ^{R}=(ε_{0}*ω^{2}_{p}*v)/(ω^{2}+v^{2}) The Attempt at a Solution %ionospheric profile for earth-ionosphere waveguide as coefficients e = 1.602e-19; % electron charge...

I have no way to test an idea that I have been thinking about, but would like some one to test it. To keep it simple all you would need to do is take a piece of nickle and shock it with electricity. This would need to be done in a place that has a way to test if there is an Ionosphere. This...

What is about the minimum wavelength that can bounce off of the ionosphere?

I've read that ionosphere mirrors the short radio waves (25-30 MHz). So 2 questions: Why this happens? There is material on the internet, but it's rather complicated for me so far, I've just started to study physics. So I'd appreciate if someone explains this in more or less simple way. Why...

So as what i understand of this piece of our sky is that it is a bunch of ions collected together that does what? I know that we bounce radio signals off of it for HAM radios and other types of communications. I don't understand the ionosphere very much and would like to learn. What happens if...

Is it possible and/or practical to shoot a beam of full spectrum (or limited spectrum) light into the ionosphere and have it diffuse across the sky the way we do with radio waves? I'm wondering if it's possible to make psuedo-daylight (or something akin to it) at night.

The tunguska event has no precedent in recent human history.If it did have one we would have heard in folklore of tidal waves,forests being flattened,towns,cities etc.There would even be craters in the ground formed recently.Did humans do something that enabled tunguska to happen.I have heard...

A smooth surface aborbs less sunlight than a rough one because more light is reflected. It takes relatively little energy to disturb a smooth surface.If the sea becomes more turbulent because of a changing wind direction or wind speed does the sea heat up more by absorbing more sunlight.And...

Hi, why the reflection in ionosphere isn't direct?,
