Particle Size Retrieval

While the Extinction Retrieval assumes the size distribution parameters, \(r_g\) and \(\sigma_g\), it is possible to retrieve information about these parameters with multi-wavelength measurements. The coupled retrieval largely follows the work by [Rieger et al., 2014], that retrieves the median radius and number density while assuming a fixed lognormal width. These parameters are converted to effective radius and extinction as they are less sensitive to the assumed width.
