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 کاملDual Wavelength, Dual Polarized Radar System for Gpm Ground Validation Experiments
Precipitation affects the daily lives and economic wealth of the citizens of United States and elsewhere. Obtaining quantitative measurements of precipitation on a global scale has been identified by NASA, the USWRP and other government organizations as essential to improving our ability to forecast and understand weather events [1]. Launched in 1997, the Precipitation Radar (PR) aboard the Tro...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولUse of the sea surface as reference for GPM dual-frequency radar algorithms
In airborne and spaceborne radar remote sensing of clouds and precipitation, measurements of the sea surface normalized radar cross section σ are widely used to constrain and condition algorithms for the retrieval of atmospheric parameters. In the Tropical Rainfall Measuring Mission, the Path Integrated Attenuation (PIA) of the Ku-band Preciptitation Radar (PR) are estimated by comparing the su...
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...
