Selected hydrometeor field feature (cluster) statistics from the kasacrppihydfeat data product are projected onto a corresponding kasacrppihydmask spatial mask for the COMBLE KASACR PPI scan at 0.5 degrees elevation on March 13, 2020, at 17:45 Coordinated Universal Time. This panel provides morphological feature properties: area in square kilometers (numbers on feature centers), fitted ellipses (transparent pink shapes), and semi-major axes of fitted ellipses (red lines). Black dashed lines designate the KASACR effective field-of-view boundaries. This panel was generated using the PPIHYD demo Jupyter Notebook and provided by Israel Silber, Pacific Northwest National Laboratory.

Hydrometeor Field Spatial Statistics Derived From Radar Scans

An initial set of Plan Position Indicator (PPI) Hydrometeor Field Statistics (PPIHYD) evaluation data is now available for the 2019–2020 Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE).
