POMME Kalman analysis of physical variables: datasets and gridded fields

the programme ocean multidisciplinaire meso echelle (pomme) was designed to describe and quantify the role of mesoscale processes in the subduction of mode waters in the northeast atlantic. intensive situ measurements were maintained during 1 year (september 2000 - october 2001), over a 8 degrees square area centered on 18 degrees w, 42 degrees n. in order to synthesized the in-situ physical observations, and merge them with satellite altimetry and surface fluxes datasets, a simplified kalman filter has been designed. daily fields of temperature, salinity, and stream function were produced on a regular grid over a full seasonal cycle. we propose here the gridded fields (ka_ files) and the in-situ datasets used by the analysis (data_ files).

本程序海洋多学科中尺度（Pomme）旨在描述并量化中尺度过程在东北大西洋模式水下沉没作用中的角色。在2000年9月至2001年10月的一年时间里，对8度平方区域内以18度西经、42度北纬为中心的区域进行了密集的现场测量。为了综合现场物理观测数据，并将其与卫星测高数据和表面通量数据集相结合，设计了一种简化的卡尔曼滤波器。在全年季节周期内，以规则网格生成了温度、盐度和流函数的每日场。在此，我们提出网格化场（ka_文件）和用于分析中的现场数据集（data_文件）。
