to ease the interpretation by the end users. In addition, the rainfall relations in DROPS1.0 are derived based on simulated drop size distribution (DSD) data ( Cifelli et al. 2011 ), which may not be sufficient to represent real rainfall microphysical properties. This paper aims to improve DROPS1.0 for more accurate and robust rainfall estimation, especially in an operational environment. Compared with DROPS1.0, the improved dual-polarization radar rainfall algorithm (hereafter refer to as DROPS2

platform for comparison with the DPR because of its similar operational frequency and the ability to be deployed for targeted, long-term observation of meteorological events. The D3R provides high-temporal-resolution and high-spatial-resolution observations for a more detailed understanding of precipitation that will ultimately be used to refine algorithms for retrieval of microphysical properties ( Vega et al. 2014 ). The D3R is equipped with a solid-state transmitter system and coaligned, beam

sensors, databases, computational clusters, and a variety of complex models in order to address research questions in near–real time. However, site-specific limitations may prevent the implementation of solutions that are otherwise readily available. In IFloodS, campaign participants faced the challenge of deploying six scanning weather radars, 20 optical disdrometers, about 100 tipping-bucket rain gauges, 25 soil moisture stations, and 100 stream gauges alongside a few other specialized instruments
