Resumo
This work deals with the analysis of the electronic subsystem of
a multiwavelength elastic scanning lidar. Several calibration tests are
applied to the Cubatão scanning lidar placed at the industrial area of
Cubatão in the State of São Paulo (Brazil), in order to improve the
knowledge of its performing itself and to design protocols for correcting
lidar signal for undesirable instrumental effects. In particular, the trigger
delay is assessed by means of zero-bin and bin-shift tests for analog (AN)
and photo-counting (PC) signals, respectively. Dark current test is also
performed to detect potential range-dependency that could affect lidar
products. All tests were performed at different spatial resolutions. These
instrumental corrections were applied to a case study of data acquired for
characterizing the optical and microphysical properties of particles in an
industrial flare. To that aim, a graphical method based on the space defined
by the extinction-related Angström exponent versus its spectral curvature is
used to derive the contribution of fine aerosol to extinction and the size of
the fine aerosols in the industrial flare, therefore revealing features of the
processes occurring inside the flame. Our study demonstrates the potential
of this new technique for the study and measurement of industrial
emissions.
