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...
متن کاملSimilarities and Improvements of GPM Dual-Frequency Precipitation Radar (DPR) upon TRMM Precipitation Radar (PR) in Global Precipitation Rate Estimation, Type Classification and Vertical Profiling
Spaceborne precipitation radars are powerful tools used to acquire adequate and highquality precipitation estimates with high spatial resolution for a variety of applications in hydrological research. The Global Precipitation Measurement (GPM) mission, which deployed the first spaceborne Kaand Ku-dual frequency radar (DPR), was launched in February 2014 as the upgraded successor of the Tropical...
متن کاملSimulation of Space-borne Radar Observations of Precipitation at Ku and Ka Band
Global Precipitation Measurement (GPM) is poised to be the next generation precipitation observations from space after the TRMM mission. The GPM will carry a dual-frequency precipitation radar (DPR), operating at Ku and Ka band frequencies. Since space-borne precipitation observations have never been done in Ka band before, extensive research work on dualfrequency radar, including electromagnet...
متن کاملMicrowave radar signatures of precipitation from S band to Ka band: application to GPM mission
Radars at different frequencies have been used over five decades for observing precipitation. S and C bands have been employed for long range coverage observations. Dual-polarization X-band radars have been shown to be useful for networked applications. Space borne precipitation radars have been at Ku band, or higher frequencies such as Ka, as in the GPM mission. This paper presents a comprehen...
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...
