In support of the TOGA COARE objectives, this project is a study of the surface radiative processes in the western Pacific warm pool region. The objective of the program is to provide analyses of: sea-surface "skin" temperature, precipitable water, cloud properties, and components of the surface longwave and shortwave radiative fluxes, with spatial resolution of 30 km and temporal resolution of 3 hours for the entire TOGA COARE primary domain. The data for the analyses will be obtained principally by satellite remote sensing, with the ISCCP data set and algorithms playing a substantial role. Available surface and aircraft data will be utilized to validate the remote sensing algorithms and will also be blended with the satellite retrievals for the final analysis products. An aircraft sub-program is proposed specifically to investigate cloud-radiative properties, and to validate the satellite-derived surface fluxes. The proposed research will be accomplished in three stages: i) remote sensing pilot study to develop and compare satellite algorithms; ii) validation of remote sensing algorithms using TOGA COARE IOP surface and aircraft observations and preparation of high-resolution analyses for the IOP; and iii) diagnostic and modelling studies utilizing the analyzed fields. Diagnostic studies of the modulation of the analyzed surface radiative fluxes by synoptic and mesoscale atmospheric forcing will be conducted. The temporal response of the ocean mixed layer to fluctuations in the surface radiative fluxes will be examined using an ocean mixed- layer model. The ocean mixed-layer model will be coupled to an atmospheric radiative-convective model to assess the radiative and cloud feedbacks occurring between the atmospheric and oceanic boundary layers. This research is important because it serves as one of the principal TOGA/COARE studies of the processes responsible for the coupling of the ocean-atmosphere in an especially climate sensitive region of the world, the western Pacific Ocean, the field site of TOGA/COARE.

为了支持Toga Coare目标，该项目是对西太平洋暖池区域的表面辐射过程的研究。 该程序的目的是提供：海面“皮肤”温度，令人降低的水，云特性以及表面长波和短波辐射通量的组件，空间分辨率为30 km，整个Toga Coare主要领域的时间分辨率为3个小时。 分析的数据将主要通过卫星遥感来获得，ISCCP数据集和算法发挥了重要作用。 可用的表面和飞机数据将用于验证遥感算法，并将与最终分析产品的卫星检索混合。 提出了一项飞机子程序，专门研究云辐射特性，并验证卫星衍生的表面通量。 拟议的研究将分为三个阶段：i）开发和比较卫星算法的遥感试验研究； ii）使用toga coare IOP表面和飞机观测以及对IOP的高分辨率分析的准备验证遥感算法； iii）利用分析领域的诊断和建模研究。 将对通过概要和中尺度大气强迫调节的调节表面辐射通量调节的诊断研究。 海洋混合层对表面辐射通量波动的时间响应将使用海洋混合层模型检查。 海洋混合层模型将耦合到大气辐射感染模型，以评估大气和海洋边界层之间发生的辐射和云反馈。 这项研究很重要，因为它是负责在世界上特别敏感地区，西太平洋（toga/coare的现场地点）中，对海洋大气耦合的过程的主要toga/coare研究之一。
