This study demonstrated preliminary results in diagnosis of the numerical model with reference to the TRMM/PR, examples of the GPM/DPR synthetic data, and application of the synthetic data to the algorithm development in the nonuniform beamfilling correction method. These were performed using a satellite radar simulation algorithm by the National Institute of Information and Communications Technology...
To derive the sub-footprint scale sigma0 from TRMM/PR observation datasets, a new formulation to calculate the sub-footprint sigma0 is devised. The sub-footprint scale sigma0 would be useful to, (1) relieve the underestimate of the path integrated attenuation (PIA) at off-nadir angle observations over land, and (2) examine the nonuniformity of rainfall. The PIA estimated from sigma0 of the standard...
After the great success of the Tropical Rainfall Measuring Mission (TRMM), Global Precipitation Measurement (GPM) started as an international mission and follow-on mission of the TRMM project to obtain more accurate and frequent observations of precipitation. The accurate measurement of precipitation will be achieved by the DPR installed on the GPM core satellite. In order to estimate accurate precipitation...
