EC-TOOC umbrella proposal - EarthCARE, Tropical Oceans & Organized Convection

EC-TOOC使命（“EarthCARE，Tropical Oceans and Organized Convection”发音“easy to see”）旨在了解对流和中尺度过程的组织如何影响热带辐合带的结构和动态及其大尺度环境。EC-TOOC将把联合收割机被动和主动云遥感与投下式探空仪的密集现场探测相结合，研究其汇合形成ITCZ的气团的变化。通过与EarthCARE卫星立交桥协调空中采样，EC-TOOC将把其测量结果与新一代卫星遥感联系起来。即将发射的EarthCARE卫星将成为一个空间云观测站，使我们能够将地方研究扩大到全球范围。为了建立对EarthCARE产品的信心并告知其最智能的使用，我们将集中使用HALO underflights进行验证。EC-TOOC将把之前的任务（NARVAL-South、NARVAL-II和EUREC 4A）案例扩展到缺失的对流和气溶胶系统，并通过关注ITCZ附近和ITCZ的深对流，为更广泛地了解热带海洋上空的云环流耦合做出贡献。HALO飞机将于2024年夏季分别在巴巴多斯和佛得角停留三周，对整个北大西洋热带地区的对流和气溶胶状况进行采样。该活动将在2024年10月活动结束前通过Oberpfaffenhofen的中纬度EarthCARE验证航班进行补充。EC-TOOC的HALO部署同样得到了马克斯普朗克气象研究所、德国航空航天中心（DLR）和德国科学基金会（DFG）的支持。它吸引了广泛的国际关注，并可能成为其他活动的核心，例如计划中的BOWTIE船运动或法国在佛得角的SAFIRE-ATR 42飞机的设想贡献。

The EC-TOOC mission (“EarthCARE, Tropical Oceans and Organized Convection” pronounced ”easy to see”) seeks to understand how organization of convection and meso-scale processes, influence the structure and dynamics of the inter-tropical convergence zone (ITZC) and its large scale environment. EC-TOOC will combine passive and active cloud remote sensing with intensive in-situ soundings by dropsondes to study the transformation of air masses whose confluence forms the ITCZ. By coordinating the airborne sampling with EarthCARE satellite overpasses, EC-TOOC will link its measurements to a new generation of satellite remote sensing. The upcoming EarthCARE satellite will become a spaceborne cloud observatory and will enable us to extend local studies to global scale. To establish confidence in EarthCARE products and inform their most intelligent use, we will intensively use HALO underflights for validation purposes. EC-TOOC will extend the previous missions (NARVAL-South, NARVAL-II and EUREC4A) cases to missing convective and aerosol regimes and contribute to a broader view of cloud-circulation coupling over the tropical oceans by focusing deep convection close to and at the ITCZ. The HALO aircraft will be stationed at Barbados and Cap Verde for three weeks in summer 2024, respectively, to sample convection and aerosol regimes over the entire tropical North Atlantic. The campaign will be complemented by further mid-latitude EarthCARE validation flights out of Oberpfaffenhofen by the end of the campaign in October 2024. The HALO deployment for EC-TOOC is equally supported by the Max Planck Institute for Meteorology, by the German Aerospace Center (DLR) and by the German Science foundation (DFG). It attracts broad international attention and likely will be a nucleus for additional activities, like e.g. the planned BOWTIE ship campaign or an envisioned contribution of the French the SAFIRE-ATR42 aircraft at Cape Verde.
