This manuscript describes the optimal retrieval process for deriving snowfall from single millimeter-wavelength radar reflectivity observations and represents a derived uncertainty analysis divided into the relevant error sources in the process. The manuscript is logically and well structured, and fluently written. The topic has been walked through by describing the steps nicely and in an informative way, and the manuscript was very nice to read. Although the topic is not necessarily very

... when more recently the tendency has been on describing the multi-frequency retrieval processes or retrievals combining single-frequency with Doppler-velocity information, the way the authors describe the details in the process, and especially, the factors influencing the uncertainty, the manuscript has a significant contribution and is relevant and interesting for the C1
