Paper Abstract
In this presentation we will discuss the performance of classification and retrieval algorithms for spaceborne cloud and
precipitation radars such as the Global Precipitation Measurement mission [1] Dual-frequency Precipitation Radar
(GPM/DPR) [2], and notional radar for the Aerosol/Clouds/Ecosystem (ACE) [1] mission and related concepts.
Spaceborne radar measurements are simulated either from Airborne Precipitation Radar 2nd Generation (APR-2, [3]) observations, or from atmospheric model outputs via instrument simulators contained in the NASA Earth Observing
Systems Simulators Suite (NEOS3). Both methods account for the three dimensional nature of the scattering field at resolutions smaller than that of the spaceborne radar under consideration. We will focus on the impact of nonhomogeneities of the field of hydrometeors within the beam. We will discuss also the performance of methods to identify
and mitigate such conditions, and the resulting improvements in retrieval accuracy. The classification and retrieval
algorithms analyzed in this study are those derived from APR-2’s Suite of Processing and Retrieval Algorithms
(ASPRA); here generalized to operate on an arbitrary set of radar configuration parameters to study the expected
performance of spaceborne cloud and precipitation radars. The presentation will highlight which findings extend to other
algorithm families and which ones do not.
