The goal of this project is to support the deployment of the newly developed C-band Doppler, polarization radar on the research vessel (R/V) Roger Revelle to support the SPURS-2 cruise, to be conducted in the eastern tropical Pacific intertropical convergence zone (ITCZ) near 10N-125W from mid-October to mid-November 2017. SEA-POL will mark the first deployment of a polarimetric Doppler radar to study tropical convection from a ship platform. The project seeks to gain new insights into tropical deep cloud formations including how these deep clouds (called "convection") respond to sea surface temperature (SST) changes and the modulation of ITCZ convection by Easterly Waves. Soundings launched from the ship will be used to characterize the environmental convective available potential energy (CAPE) and shear to provide important context for the radar measurements. New ideas will be explored on spectral processing of the received radar signals to suppress sea clutter.The most important features of this EAGER project are that: (i) it provides a seaborne polarimetric radar platform (previously tested on land) deployed on an ocean field campaign (SPURS-2), (ii) will provide unprecedented observations of cloud microphysical processes in both tropical convection and stratiform cloud structures, and (iii) the field study will verify stated goals of the previously funded NSF MRI project to develop the SEA-POL radar. This project supports the creation of rain maps to support the science team during the SPURS-2 deployment at sea. Rainfall data will be used in conjunction with other onboard experiments from the same research vessel and to validate satellite estimates of ocean salinity. The results of this field campaign will be of interest to the radar community and, more broadly, to those interested in the microphysical processes of clouds and rainfall at sea ? particularly associated with the ITCZ. This project will also fund the training of one postdoctoral research scientist and a graduate student.

该项目的目标是支持在研究船(R/V)Roger Revelle上部署新开发的C波段多普勒偏振雷达，以支持Ssps-2号巡航，该巡航将于2017年10月中旬至11月中旬在东热带太平洋热带辐合带(ITCZ)10N-125W附近进行。SEA-POL将标志着首次在船舶平台上部署极化多普勒雷达来研究热带对流。该项目试图获得对热带深云形成的新见解，包括这些深云(称为对流)如何响应海表面温度(SST)的变化，以及东风波对ITCZ对流的调制。从船上发射的探测将被用来描述环境对流可用势能和切变，以便为雷达测量提供重要的背景。将探索对接收到的雷达信号进行频谱处理以抑制海杂波的新想法。这一迫切项目最重要的特点是：(I)它提供了一个部署在海洋领域战役(SPRS-2)上的海上极化雷达平台(以前在陆地上进行过测试)，(Ii)将提供对热带对流和层状云结构中的云微物理过程的前所未有的观测，以及(Iii)实地研究将验证先前资助的NSF MRI项目发展海洋POL雷达的既定目标。该项目支持创建雨图，以支持在海上部署Ssps-2期间的科学团队。降雨量数据将与同一研究船的其他船上实验一起使用，并验证卫星对海洋盐度的估计。雷达界和更广泛地说，对海上云和降雨的微物理过程感兴趣的人，将会对这一实地活动的结果感兴趣？特别是与ITCZ有关的问题。该项目还将资助一名博士后研究科学家和一名研究生的培训。
