Planetary Ecologist<p>Ozone–oxygen cycle (Biogeochemical cycle 🔄)</p><p>The ozone–oxygen cycle is the process by which ozone is continually regenerated in Earth's stratosphere, converting ultraviolet radiation into heat. In 1930 Sydney Chapman resolved the chemistry involved. The process is commonly called the Chapman cycle by atmospheric scientists.

I found a graphic for carbon dioxide consumption in photosynthesis, the greatest sink for atmospheric carbon dioxide I could think of. </p><p>Like many biological processes substrate concentration determines the extent of reaction during any given amount of time, but there is an upper limit. <br>Also available photosynthetic light increases extent of reaction to an upper limit. </p><p>It seems carbon dioxide concentration and light both play a factor in determining the maximum rate of photosynthesis. </p><p>Does anyone have information on real world calculations of the maximum rate of photosynthesis?</p>

I'm not sure if you've ever tried screen readers, but they go quite fast and the hashtags can be ignored. Hashtagging every word (or 3 or more words in a row) is a bigger issue that a few scattered through a toot.</p><p>Also use CamelCase in hashtags (e.g. <a href="https://atmoschem.org/tags/AtmosphericChemistry" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AtmosphericChemistry</span></a>, <a href="https://atmoschem.org/tags/AirQuality" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AirQuality</span></a>) - that makes it much easier for screen readers.</p><p>(Not a screen reader user myself)</p>
