Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Impact of Crosstalk on Reflectivity and Doppler Measurements for the WIVERN Polarization Diversity Doppler Radar (2023), IEEE Transactions on Geoscience and Remote Sensing. Implementations in other papers (listed below) may differ.

1. Generate synthetic WIVERN profiles
   Create realistic WIVERN radar profiles using CloudSat observations as input, incorporating 94-GHz reflectivity observations, ECMWF winds, and climatological LDR values. Apply noise levels appropriate to WIVERN system specifications with single-pulse sensitivity of -15 dBZ at 5-km integration.
   Quantities: One year (2007) of CloudSat data processed into WIVERN-equivalent profilesDuration: One year dataset spanning 2007Conditions: Various atmospheric conditions including ice clouds, precipitation, and clear regions
   Equipment: CloudSat 94-GHz radar observations, ECMWF wind data, Climatological LDR database
2. Simulate PDPP radar measurements
