Title
Development of cloud liquid water database using global cloud-system resolving model for GPM/DPR algorithm.
Abstract
The JAXA-NASA Joint Algorithm Team has developed the Level 2 algorithm for Dual-frequency Precipitation Radar (DPR) onboard the Global Precipitation Measurement (GPM) core observatory, which will be launched in 2014. Correction method for attenuation by cloud liquid water (CLW) is one of future issues in the DPR algorithm. Recently, a 3.5km-mesh global simulation has been performed using a Nonhydrostatic ICosahedral Atmospheric Model (NICAM). The NICAM is a global cloud-system resolving model (GCRM), and explicitly calculates moist convection using a cloud microphysical scheme. In this work, vertical profiles of the CLW are classified with reference to temperatures and intensities of surface rain rate (SRR) using the NICAM data. Overall, the CLW amount tends to increase when the SRR increases. In the Tropics such as 15S-15N, clear peaks are found around 10-15 degrees Centigrade with small SRRs. This can be connected with shallow rainfall. In large SRRs, peaks are around the Freezing Level, which can be related to tall rainfall.
