Ozone layer depletion is not a joke; it is a serious environmental
issue besetting this present world: it got nations to agree to cut the
use of gases responsible for it by replacing them with non-harmful ones.
Ozone depletion allows harmful ultra violet (UV) rays to pass; this, on
increased exposure, can cause skin cancer, cataract and immune system
suppression in humans.
The ozone layer is expected to be repaired naturally by mid-century
when most Ozone Depleting Substances (ODSs) there will fizzle out and
lost ozone molecules will be replenished in reactions. This time is far
away even as evolving environmental issues from the upper atmosphere are
getting complicated with new studies and current emission prodigality. A
research work on geoengineering ozone layer suggests a procedure to
repair the ozone layer aside the sole option of natural repair to come
This research mimics the normal process for protection from harmful
UV rays occurring at the ozone layer. While avoiding assumptions, the
research submits a workable procedure that will give desired results
when used. The research presents that oxygen is conveyed from Planet
Earth and discharged as gas to depleted parts of the ozone layer.
Discharged oxygen should join the number of natural existing oxygen
molecules in the ozone layer and continue in reactions likewise.
Oxygen is preferred because of its involvement in reactions in the
ozone layer and because it is more chemically stable than ozone. Oxygen
use for this research is similar to that used with rocket engines where
it is stored as liquid and passed to a combustion chamber to vaporize
and mix with other fuels to power rockets. A tank of liquid oxygen will
be conveyed from planet earth using an airship or an unmanned aircraft;
it will fly to depleted parts of the ozone layer where it will
discharge oxygen under high pressure as gas, while hovering in that part
Point of discharge is low stratospheric altitude (around 20km above
sea level) where wind and turbulence is bearable. This research is in
three phases for review. First is the choice of conveyer and the volume
of liquid oxygen tank. Second is the point of discharge in the
stratosphere where depletion is observed and ODSs or Green House Gases
(GHGs) will not affect the objective of incoming molecules to close
ozone depleted parts (or the ozone hole). The third phase of this
research is measurements that will show activities of discharged oxygen
and its extent of repair.
These phases are not beyond familiar practice in today's space and
climatic science. Some of the usual measurements of ozone from ground
(by brewers or ballonsondes) or from space (by satellites) can tell to
some extent activities of oxygen in the ozone layer. These, too, can
help with information on freshly injected gas. The choice of conveyer is
dissected in details here but airships seem to be the best pick.
Experimentation of this research is posited for the future, giving more
time to develop this work and increase observation on conditions aligned
with or against phases in this procedure. Countries around the Polar
regions may do well to pick this research for review.
Canada, Denmark, New Zealand and South Africa, may put to study this
work that doesn’t cost so much, to gradually affirm as an experiment
that will desirably repair depleted parts of the ozone layer. Ozone
Layer Geoengineering (OLG) should not have the risks generally feared
for geoengineering because gas will be infixed at a measure that does
not exceed total ozone amounts for that part. This safe range will not
harm our delicate climate system and will not lead to withdrawal of the
process due to an unwanted shift.
We need to begin to prepare and as OLG
presents a starting point; a review report describes how this research
should come but should move from there to studies on each part of the
procedure for adjustments. The Montreal Protocol
has, to some extent, settled ozone depletion but growing deviations in
the upper atmosphere and from the ground threaten projected repair.
Geoengineering the ozone layer is not being talked about widely yet, but
is an answer to the ozone depletion encumbrance.
