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
