NCEP/NCAR Reanalysis Project

The NCEP/NCAR Reanalysis Project is a joint project between the National Centers for Environmental Prediction (NCEP, formerly "NMC") and the National Center for Atmospheric Research (NCAR). The goal of this joint effort is to produce new atmospheric analyses using historical data (1948 onwards) and as well to produce analyses of the current atmospheric state (Climate Data Assimilation System, CDAS).

国家环境预测中心（NCEP，原名NMC）与国家大气研究中心（NCAR）联合发起的NCEP/NCAR再分析项目旨在利用历史数据（自1948年起）生成新的大气分析，并进一步对当前大气状态进行分析（气候数据同化系统，CDAS）。
