Expectation maximization and the retrieval of the atmospheric extinction coefficients by inversion of Raman lidar data

Garbarino, Sara Sannino, Alessia Boselli, Antonella

We consider the problem of retrieving the aerosol extinction coefficient from Raman lidar measurements. This is an ill-posed inverse problem that needs regularization, and we propose to use the Expectation-Maximization (EM) algorithm to provide stable solutions. Indeed, EM is an iterative algorithm that imposes a positivity constraint on the...
