EAGER: Deploying the Colorado State University (CSU) SEA-POL Radar to SPURS-2

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SPURS-2巡航，该巡航将于2017年10月中旬至11月中旬在10 N-125 W附近的东热带太平洋热带辐合区（ITCZ）进行。SEA-POL将标志着首次部署偏振多普勒雷达，从船舶平台研究热带对流。该项目旨在获得对热带深云形成的新见解，包括这些深云（称为“对流”）如何响应海面温度（SST）变化以及东风波对ITCZ对流的调制。 从船上发射的探测将用于表征环境对流可用势能（CAPE）和切变，为雷达测量提供重要的背景。研究人员将探讨新的构思，对接收到的雷达信号进行频谱处理，以抑制海杂波。这项EAGER计划最重要的特点是：（i）提供海上极化雷达平台（以前在陆地上测试过）部署在海洋实地活动（SPURS-2），（ii）将提供前所未有的热带对流和层状云结构中云微物理过程的观测，和（iii）现场研究将验证先前资助的NSF MRI项目开发SEA-POL雷达的既定目标。 该项目支持创建雨图，以支持科学团队在海上部署SPURS-2。 降雨数据将与同一研究船上的其他船上实验结合使用，以验证卫星对海洋盐度的估计。 这场实地活动的结果将是感兴趣的雷达社区，更广泛地说，那些有兴趣在海上云和降雨的微物理过程？特别是与ITCZ有关的。 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。

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.
