WCR L2 Up-Down Merged with Vertical Velocity Estimate Improved using Sounding Winds


This dataset contains 24 IOPs (23 Research Flights - IOP 18 had no flights) worth of data obtained from the Wyoming Cloud Radar (WCR) aboard the UWKA Research Aircraft. The data is considered an analysis product rather than the standard WCR data offering due to an additional field (w_corrected) that has been appended to the standard Level 2 (L2) file. This analysis is only being offered with the L2 merged (up-down antennas) product. The w_corrected field employs a sounding correction to produce an estimate of the hydrometeor vertical velocity field from the WCR along level flight legs.  The sounding name/time and w_corr field descriptors have been included as attributes to the .nc (netCDF) files. In general, the IPC Crouch Sounding from the SNOWIE project was employed to correct the w field. This is a single sounding closest to the center flight time for each RF in SNOWIE, at a location closest to the UWKA flight tracks in SNOWIE (Crouch). These data are available as tar.gz files by flight.
