这项提议支持国家大气研究中心协助陆军研究实验室(ARL)在高级研究天气(ARW)研究预报模式的社区版本中准备观测-轻推代码数据同化的书面描述。该文档可能会建议对ARW的可用配置进行更改。此外，NCAR将与ARL合作，研究社区ARW中的观测推送和NCAR研究航空实验室开发的4DWX系统中的观测推送的相对性能。结果将是一篇至少写一篇期刊文章。此外，还将编写一份白皮书，介绍在网格间隔小于1.0公里的情况下应用ARW进行模拟的最佳做法。

This proposal supports the National Center for Atmospheric Research to assist the Army Research Laboratory (ARL)in preparing a written description of the observation-nudging code data assimilation in the community version of the Advanced Research Weather (ARW) Research Forecast model. The document might suggest changes to the available configurations of the ARW. In addition, NCAR will collaborate with ARL on a studey of the relative performances of the observation nudging in the community ARW and the observation nudging in the 4DWX system developed by NCAR Research Aviation Laboratory. The result will be a written at least one journal article. Furthermore, a white paper will be produced conveying best practices for applying the ARW for simulations at gride intervals less than 1.0km.
