The possible impact of deep convective overshooting over land has been explored by six simultaneous soundings of water vapour, particles and ozone in the lower stratosphere next to Mesoscale Convectiv...
Improved rainfall estimates in convective storms using polarisation diversity radar
polarisation radar rainfall calibration
