Medidas de Ozônio a Bordo do Avião Bandeirantes do INPE

Abstract


Ozone concentration measurements on board of an aircraft indicated a relatively sharp variation between Curitiba and São Paulo, at a height of 700 mb (3 km), with the relative ozone concentration decreasing by a factor of 2. A possible explanation for our observations is purely chemical, on the basis of the high pollution emissions in the vicinity of São Paulo. Simultaneous meteorological data obtained by radio soundings lead to two different alternative interpretations. The first of these assumes that the sampled air in São Paulo is of marine origin being thus less rich in ozone. The second points out that over Curitiba, the mixing layer had a higher upper limit, with the aircraft exiting the planetary mixing layer just after Curitiba.
