CASTREJON-GARCIA, R.; VARELA, J. R.; CASTREJON-PITA, J. R.  y  MORALES, A.. The laser-backscattering equations and their application to the study of the atmospheric structure. Rev. mex. fis. [online]. 2002, vol.48, n.6, pp.513-518. ISSN 0035-001X.

In this work a method for interpreting backscattering signals acquired by a lidar is described. The method is based on the elastic scattering of laser radiation due to gases and particles suspended in the atmosphere (bulk effects). We propose a space-time diagram which helps to evaluate the arguments of the equation that serves to calculate the lidar signal in terms of the backscattering coefficient. We describe how the system detects gradients on this coefficient, along the laser optical path. To illustrate the method, we present some typical lidar results obtained in the neighborhood of Mexico City.
