Recovery of three-dimensional wind and temperature fields from simulated single-Doppler radar data

This method uses a dynamic model, and attempts to determine the initial conditions of the unobserved flow and thermodynamic fields that have generated the time sequence of observed fields. A cost function is defined to measure the difference between the model solutions of the observed variables and the observations. A set of adjoint equations is constructed to determine the sensitivity of the cost function to initial state errors in those not observed. The initial state variables are then adjusted to minimize those errors. -from Authors
