Based on a successful multidisciplinary and international (Fr-US) CONCORDIASI campaign, an evaluation of high resolution weather simulations using AMPS (Antarctic Mesoscale Prediction System) code will be made by comparing modeled and observed data. The extensive CONCORDIASI observation set will allow unprecedented comparison of the regional performance of the model outputs over Antarctica and the Southern Ocean. Approximately 640 dropsondes were deployed from some 13 balloon flights during a 7 week period in 2010. The dropsondes yield in-situ profiles of wind, temperature, pressure and humidity through the Antarctic atmosphere. In turn the performance of the model may serve as diagnostic for a number of key meteorological phenomena in the Antarctic, including atmospheric circulation and dynamics, and the ability to determine momentum balance, moisture and radiation over the continent during austral summertime. Educational goals include graduate student training and involvement, and potentially enhanced operational skill of forecast models such as AMPS, used operationally in the USAP program

基于一个成功的多学科和国际（法国-美国）CONCORDIASI活动，使用AMPS（南极中尺度预报系统）代码的高分辨率天气模拟的评价将通过比较模拟和观测数据。广泛的CONCORDIASI观测集将允许对南极洲和南大洋上空模式输出的区域性能进行前所未有的比较。 在2010年7周的时间里，从大约13次气球飞行中部署了大约640个下投式探空仪。投下式探空仪产生南极大气中风、温度、压力和湿度的现场剖面图。反过来，该模型的性能可以作为诊断的一些关键的气象现象在南极，包括大气环流和动力学，并有能力确定动量平衡，湿度和辐射在南极洲的夏季。教育目标包括研究生培训和参与，以及潜在的增强预测模型（如在USAP计划中操作使用的AMPS）的操作技能
