Talk:Earth's atmosphere

This article was ported here from Wikipedia

I have taken it apart and rebuilt with major reformatting, major deletions, majors additions, new tables and a new image. It is now a full-fledged CZ article. Milton Beychok 18:48, 18 August 2009 (UTC)

My first venture outside my field of expertise

This is my first venture outside my field of expertise. CZ needed this article, so I ported it here from WP and re-did it (see just above).

I would very much appreciate it if someone with atmospheric science expertise would offer comments and/or edits. Milton Beychok 18:59, 18 August 2009 (UTC)

Some initial thoughts, which may or may not fit.

Let's be sure to have some redlinks for radio propagation, which isn't restricted to the ionosphere (e.g., troposcatter). I'll try to fill them in.

I'm not sure if it's worth mentioning the issue of microclimatology vs. climatology/meteorology, and how terrain features can have surprising effects. This is something I learned to appreciate when working on the Vietnam-era "People Sniffer" (an ammonia detector), and also in chemical warfare.

Will spend some more time later -- I am getting some notes out of an overdue book I need to return to the library before it closes.Howard C. Berkowitz 19:29, 18 August 2009 (UTC)

Milton, in reply to your post on my talk, I think the article is excellent. As a general rule I'm against ex-wikipedia content appearing on CZ, not out of any dislike for WP (I'm a member of both) but just because I want to see CZ stand on its own feet. But putting that aside this time, I think it's excellent. CZ needs more like you. My knowledge is more extra-terrestrial, but I'll see if there's anything I can add at some point.

Milton, it looks good to me, very readable (except for "lapse rate"). I have the following very minor comments: Maybe you should explicitly mention that the inversion layer is not shown in the figures? I was looking for it. Further you write 101,325 Pascals. I'm somewhat pedantic about this, but the accepted (counterintuitive) rule is: if name of person is in full then lowercase, if abbreviated then uppercase, e.g., 1 N = 1 newton. And one should not use plural, hence 101,325 Pascals ---> 101,325 pascal or 101,325 Pa. (Also 26,437 Pascals -->26,437 pascal). As I said, I don't know what a "lapse rate" is and its link is red. Equation 2 is the Boltzmann distribution, known from thermodynamics; maybe it is useful to mention this name? The table below --> the table on the right (or is this my browser?). That's it, cheerio, --Paul Wormer 07:05, 19 August 2009 (UTC)

(no indent) Paul, thanks for the comments:

• I will change the Pascals to pascals.
• As for lapse rate, I am currently gathering information in preparation for that being the next article I plan to write. Lapse rates are covered in my book about air pollution dispersion modeling ... so writng an article about lapse rates will give me a chance to cite my book.
• I'll try to work in mention of inversion layers ... although they are not always present, only under certain conditions. So I didn't consider them to be a bona fide atmospheric layer.
• Nothing wrong with your browser. The table was below at first. When I moved it to the right, I forgot to change the text ... which I will do now.
• I haven't the faintest notion what the Boltzmann distribtion is. Did you mean that Equation 2 "is" the Boltzmann distribution or did you mean Equation 2 can be derived from it? Can you (I hope) provide some wording that could be used in mentioning it? The two equations were obtained from the U.S. Standard Atmosphere, 1976 cited as a reference in the article.Milton Beychok 08:13, 19 August 2009 (UTC)
