Python Hail Retrieval Toolkit (pyhail) ⛈️📡🧊

This toolkit provides a collection of hail retrieval techniques for weather radar data.

Library Dependencies

• Py-ART for ingesting data
• numpy
• netCDF4
• scipy
• scikit-image

Notebook Dependencies

• matplotlib
• cartopy

Hail Retrivals

• *Hail Size Discrimination Algorithm - HSDA (Ortega et al. 2016)
• Hail Differential Reflectivity - HDR (Depue et al. 2007)
• Maximum Expected Size of Hail - MESH witt1998 (Witt et al. 1998)
• Maximum Expected Size of Hail - MESH mh2019_75/mh2019_95 (Murillo and Homeyer 2019)
• Accumulated Hail - hAcc (Wallace et al. 2019)

*Note that the Q confidence vector from Park et al. 2009 has not been implemented and all pixels are assigned a value of q=1.

MESH is implemented for both pyart radar (PPI) and grid (Cartesian) data!
