Resumo
The Planetary Boundary Layer Height (PBLH) is one of the most important variables for studies related
to pollutant dispersion, serving as an input parameter for weather forecast models and prediction
of pollutant concentration and/or air quality indices. However, obtaining such a parameter is not an
easy task and itis restricted to regions that have radiosoundings and/or remote sensing equipment,
e.g. elastic or Doppler lidars, which, due to their high cost and the need for specialist operators, have
low availability in several countries, such as Brazil, for example. Based on this scenario, the present
work presents a comparison between the PBLH estimated using Constellation Observing System for
Meteorology Ionosphere and Climate – 2 (COSMIC-2 satellite data and MSP-1 (an elastic lidar located
at Center for Lasers and Applications – CELAP for the city of São Paulo. The results demonstrate that
in situations where the PBLH is well developed and there is not low clouds, both instruments present
very similar results. Based on this result, it is possible to replicate the methodology presented in this
work for other regions, so that it is possible, even with a low temporal resolution, to estimate the PBLH
for regions that do not have measuring instruments.
