GPM Satellite Radar Observations of Precipitation Mechanisms in Atmospheric Rivers

Multiple scattering in observations of the GPM dual‐frequency precipitation radar: Evidence and impact on retrievals

This paper illustrates how multiple scattering signatures affect Global Precipitation Measuring (GPM) Mission Dual-Frequency Precipitation Radar (DPR) Ku and Ka band reflectivity measurements and how they are consistent with prelaunch assessments based on theoretical considerations and confirmed by airborne observations. In particular, in the presence of deep convection, certain characteristics...

Global Precipitation Mission (GPM) and Dual-Wavelength Radar (DPR)

Global precipitation measurement is essential not only for the research of the global change but also for the water resources management. Currently, satellite precipitation measurement is not sufficient for the detailed study of the precipitation and is far from enough for the water resources management which requires very high spatial and temporal resolution. To fill the gap at least partly, t...

Cloud radar observations of precipitation

An innovative method for the observation of vertical air motion and raindrop size distribution in precipitation using a 94-GHz Doppler radar is demonstrated in this paper. The method is particularly appealing since it is based on fundamental physics, the scattering of microwave radiation by large particles (Mie scattering). Observations from stratiform rain are presented to illustrate the poten...

Precipitation estimation over radar gap areas based on satellite and adjacent radar observations

Continuous rainfall measurements from groundbased radars are crucial for monitoring and forecasting heavy rainfall-related events such as floods and landslides. However, complete coverage by ground-based radars is often hampered by terrain blockage and beam-related errors. In this study, we presented a method to fill the radar gap using surrounding radar-estimated precipitation and observations...
