Steps below were extracted from the paper that introduces this protocol — Riming-dependent snowfall rate and ice water content retrievals for W-band cloud radar (2025), Atmospheric Measurement Techniques. Implementations in other papers (listed below) may differ.

1. Apply viewing angle correction to radar data
   A viewing angle correction of 2.29 ± 0.39 dB was applied to correct slanted 40° radar observations to equivalent 90° vertical observations. This correction accounts for snow particle orientation effects, where falling ice and snow particles typically orient themselves horizontally in the atmosphere, resulting in lower radar reflectivity for slanted observations compared to vertical observations.
   Quantities: 2.29 dB offset correction, ±0.39 dB standard deviationDuration: Applied to all 40° observationsConditions: For comparison with vertical radar data from other sites
   Equipment: Statistical analysis of Ze distributions
