Distribution of molecules throughout the atmosphere

Click For Summary

Discussion Overview

The discussion revolves around the distribution of molecules, particularly greenhouse gases (CO2, H2O, CH4, N2O), throughout the various layers of the atmosphere. Participants explore the vertical structure of the atmosphere and seek specific data on the abundance and ratios of these gases across different altitudes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant assumes that most molecules are more abundant in the troposphere and decrease in concentration through to the mesosphere.
  • Another participant suggests searching for terms like "homosphere," "heterosphere," and "turbopause," indicating that gases are evenly mixed up to about 100 km, with exceptions for certain gases like H2O.
  • There is a mention of the turbopause marking a transition in atmospheric behavior, with a note that water vapor is a significant greenhouse gas due to its abundance.
  • Some participants provide links to resources that may contain relevant information but acknowledge that these resources do not specifically address the distribution levels of greenhouse gases.
  • One participant clarifies the difference between "latitude" and "altitude" in the context of atmospheric studies.
  • Another participant expresses dissatisfaction with the provided resources, stating they do not contain the specific graphs or data needed for greenhouse gas distribution.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific distribution of greenhouse gases throughout the atmosphere, and multiple competing views and uncertainties remain regarding the details of atmospheric composition.

Contextual Notes

Participants note limitations in the available resources, including a lack of specific data on greenhouse gas ratios and the need for further refinement of search terms to find relevant information.

Hi I was wondering if anyone knows about how molecules are distributed throughout various layers of the atmosphere.

My assumption is that most molecules would be more abundant in the troposphere and decrease throughout until the mesosphere.

does anyone know a little more about this or any links I can't seem to find what I'm looking for on the net.

Im interested in the greenhouse gas molecules (CO2, H2O, CH4, N2O) how are they distributed throughout the various layers?

I know water vapour is more abundant near water obviously but I'm more concerned with longitudinal ratios etc.

again any links would be great because I have to reference it, and ratios between each layer would be good thanks.

... sort of thing you are looking for.

Its something that has had a lot of research eg HIPPO:

... so you are pretty much spoiled for choice.

Thanks a bunch Simon.

Not really what I am looking for actually it does not have any distrubution levels of GHG's throughout the atmosphere all I could find was a temp v. latitude graph (interesting) but I am more needing a (CO2 vs latitude) graph or even better one for all GHG's.

Thank's anyway
 
That's right - I was presenting it as an example of the sort of thing you need to look for and how to phrase your searches. It is not the end of your search. You can use the information in the pdf to help you understand your querie and so refine your search-terms... do not expect to find all the info you want in one place or in a form that is just right for what you want. The pdf includes a "further reading" example as well.

Note - there is a difference between "latitude" and altitude".
 
Search for homosphere, heterosphere, turbopause. From my reading, it's all pretty evenly mixed up to 100km (H2O excepted, I'm sure).

Ok thanks.

Yep. The turbopause marks the altitude at which the atmosphere transitions from behaving like a classical gas to behaving like a bunch of weakly-interacting free particles with very large mean free paths.

H2O excepted, of course. Note that due to its abundance compared to other greenhouse gases, water is the most potent greenhouse gas of all. Another exception is O3, which is also a greenhouse gas. Ozone exists primarily in the stratosphere due to sunlight and near the Earth's surface largely due to human pollution.
