EPIC (Eastern Pacific Investigation of Climate processes in the coupled ocean-atmosphere system) is an activity of the US CLIVAR Program. EPIC 2001 consists of four components focussing on (i) intertropical convergence zone/warm pool phenomena; (ii) cross-equatorial inflow into the intertropical convergence zone; (iii) upper ocean structure and mixing and (iv) an exploratory study of boundary layer cloud properties in the southeasterly tradewind regime. The field phase of EPIC 2001 is scheduled for a 6-week period during the interval Sept 1 to Oct 15, 2001. In addition to the eight awards made by ATM, this collaborative research has awards made by NSF/OCE and NOAA/OGP.During the field phase, the PIs will collect atmospheric observations at flight levels and from GPS dropsondes, and upper ocean observations from expendable profilers. Flights will be carried out at different phases of atmospheric synoptic-scale disturbances. These data sets will be combined with observations from the TAO moorings and satellite remote sensing to describe concurrent large-scale meridional-vertical structures of the atmospheric temperature, humidity, winds, oceanic temperature, salinity, currents and air-sea fluxes in the cold tongue ITCZ complex. These data will provide a large-scale perspective for other EPIC 2001 measurements that provide micro and meso-scale structure of the ocean and atmosphere in the eastern tropical Pacific. The work is important because it will improve understanding and modeling of climate variability over the eastern tropical Pacific.

东太平洋海洋-大气耦合系统气候过程调查（EPIC）是美国CLIVAR计划的一项活动。EPIC 2001由四个部分组成，重点关注(i)热带辐合带/暖池现象；（ii）热带辐合带的跨赤道流入；（iii）上层海洋结构和混合；（iv）东南信风区边界层云性质的探索性研究。EPIC 2001的实地阶段计划在2001年9月1日至10月15日期间进行为期6周的研究。除了获得ATM的8个奖项外，该合作研究还获得了NSF/OCE和NOAA/OGP的奖项。在实地阶段，pi将收集飞行水平的大气观测数据和来自GPS下投探空仪的观测数据，以及来自消耗性剖面仪的上层海洋观测数据。飞行将在大气天气尺度扰动的不同阶段进行。这些数据集将与TAO系泊观测和卫星遥感相结合，描述冷舌ITCZ复合体的大气温度、湿度、风、海洋温度、盐度、海流和海气通量的同步大尺度经向垂直结构。这些数据将为EPIC 2001的其他测量提供一个大尺度的视角，这些测量将提供热带东部太平洋海洋和大气的微观和中尺度结构。这项工作很重要，因为它将提高对热带太平洋东部气候变化的理解和建模。
