Dual 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...

The 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...

Using Satellite Error Modeling to Improve GPM-Level 3 Rainfall Estimates over the Central Amazon Region

This study aims to assess the characteristics and uncertainty of Integrated Multisatellite Retrievals for Global Precipitation Measurement (GPM) (IMERG) Level 3 rainfall estimates and to improve those estimates using an error model over the central Amazon region. The S-band Amazon Protection National System (SIPAM) radar is used as reference and the Precipitation Uncertainties for Satellite Hyd...
