Performance assessment of drone-based photogrammetry coupled with machine-learning for the estimation of hail size distributions on the ground

Hail-producing convective thunderstorms are a major threat to agriculture and infrastructure causing large financial losses. Remote sensing techniques such as dual-polarimetric weather radar can provide hail observations over large areas, but do not necessary reflect the situation on the ground. Cur...
