Less Ozone
The amount of ozone in
the atmosphere above
Costa Rica is less than
was earlier thought,
scientist Jessica
Valverde from
Universidad Nacional
(the state National
University) reported.
According to the
researcher, in the
troposphere – from the
surface of the planet 17
kilometers, or slightly
over 10 miles, up –, the
most turbulent part of
the atmosphere and where
weather phenomena take
place, different probes
have confirmed 50 parts
per million, while in
developed countries it
reaches 250 parts per
million.
The scientist said that,
according to their data,
ozone pollution is not a
source of worry in Costa
Rica. She further
explained that there are
two types of ozone, the
one close to the
surface, which is
harmful to plants and
people, and the one
above the troposphere,
the good ozone, that
forms the layer
responsible for
filtering out solar
radiation.
