Future work & Objectives

Combined studies with MRR in order to retrieve adapted Z-R relationships and improve rain rate estimations

Comparisons with other radars (POLDIRAD + DOW) and instruments

Link radar observations with humidity field structure and evolution (GPS tomography and airborne measurements)

Detailed study of precipitation events within their meteorological context

Comparison with LaMP microphysical simulations
