Abstract
In this paper we discuss the algorithmic tools needed for data assimilation for aerosol dynamics. Continuous and discrete adjoints of the aerosol dynamic equation are considered, as well as sensitivity coefficients with respect to the coagulation kernel, the growth rate, and emission and deposition coefficients. Numerical experiments performed in the twin experiment framework for a single component model problem show that initial distributions and the dynamic parameters can be recovered from time series of observations of particle size distributions.
