Microphysical Retrieval from Dual-frequency Gpm P7.1 Observations
Following the success of the Tropical Rainfall Measuring Mission (TRMM), considerable effort has been directed at the next generation of space-based precipitation radar (PR) to be launched aboard the Global Precipitation Measuring (GPM) core satellite. The GPM mission concept is centered on the deployment of a core observatory satellite with an active dual-frequency precipitation radar (DPR), o...
متن کاملVariable pulse repetition frequency for the GPM dual-frequency radar
In space missions, the delay of a receiving signal to a transmission signal generally spans a few thousands microseconds due to long range observation. An efficient sampling can be achieved by transmitting pulses successively, as schematically shown in Fig. 1. For the later consideration, a catching integer n is to be introduced. In Fig. 1, the catching integer n is set at 11, for which a pulse...
متن کاملMultiple 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...
متن کاملDrop size ambiguities in the retrieval of precipitation profiles from dual-frequency radar measurements
The threat of flooding from landfalling tropical cyclones is a function of the local variation in rain rate and rain accumulation. To date, these have been inferred from single-frequency radar reflec-tivity measurements. However, the Tropical Rainfall Measuring Mission experience has confirmed that one of the main difficulties in retrieving rain profiles using a single-frequency radar is the un...
متن کاملThe NASA Dual-Frequency Dual-Polarized Doppler Radar (D3R) System For GPM Ground Validation
Following on the successful introduction of single-frequency (Ku-Band) weather radar onboard the Tropical Rain Measuring Mission (TRMM) satellite in 1997, the Global Precipitation Measurement (GPM) mission attempts to advance further the goal of making global scale precipitation observations by deploying the next generation of satellite-borne weather radars. The GPM satellite will carry a Ka-Ku...
