  2. Ozone–oxygen cycle - Wikipedia

    en.wikipedia.org/wiki/Ozone–oxygen_cycle

    At steady state these processes are balanced, so the rates of these reactions obey: (rate of reaction 1) = (rate of reaction 4) + (rate of reaction 5). At steady state, ozone creation is also balanced with its removal. so: (rate of reaction 2) = (rate of reaction 3) + (rate of reaction 4). It thus follows that:

  3. Dynamic steady state - Wikipedia

    en.wikipedia.org/wiki/Dynamic_steady_state

    A geomorphological system said to be in dynamic steady state has values that oscillate between maxima and minima around a central mean value.. The flux of sediment from an undisturbed drainage basin changes over the short-term as rainstorms come and go, individual hillslopes fail in mass movements, and riverbanks collapse.

  4. Brewer–Dobson circulation - Wikipedia

    en.wikipedia.org/wiki/Brewer–Dobson_circulation

    Brewer–Dobson circulation directly impacts the distribution and abundance of stratospheric ozone by moving it from the tropics towards the poles. [1] This transport helps to explain why tropical air has less ozone than polar air, even though the tropical stratosphere is where most atmospheric ozone is produced. [1]

    CALINE3 – A steady-state Gaussian dispersion model designed to determine pollution concentrations at receptor locations downwind of highways located in relatively uncomplicated terrain. CAL3QHC and CAL3QHCR – CAL3QHC is a CALINE3 based model with queuing calculations and a traffic model to calculate delays and queues that occur at ...

  6. Very short-lived substances - Wikipedia

    en.wikipedia.org/wiki/Very_short-lived_substances

    A steady decline of about four percent in the total amount of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. Very short-lived substances (VSLS) are ozone-depleting halogen-containing substances found in the stratosphere. These substances have very short ...

  7. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the atmosphere, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation.

  8. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    The ozone layer in the stratosphere blocks harmful UV radiation from reaching the surface of the Earth. A gamma ray burst would deplete the ozone layer, allowing UV radiation through. The mechanism describing the formation of the ozone layer was described by British mathematician and geophysicist Sydney Chapman in 1930, and is known as the ...

  9. Ozone layer - Wikipedia

    en.wikipedia.org/wiki/Ozone_layer

    The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...
