国家自然科学基金大气科学学科二级申请代码下设研究方向与关键词解读:D0509大气观测、遥感和探测技术与方法

为顺应新一轮科技发展革命，国家自然科学基金委员会积极开展了以“优化学科布局”为主要任务之一的改革工作，学科申请代码的调整是该任务的重要组成部分和切入点。从2019年到2022年，国家自然科学基金委大气科学学科对二级申请代码进行了调整，将与大气探测相关的研究归并至“D0509大气观测、遥感和探测技术与方法”，并将其定义为“支撑技术”板块，以区别于“分支学科”和“发展领域”。本文对D0509二级代码的修订过程进行了介绍，并从大气观测、遥感和探测技术与方法的重要性、内涵与外延、发展趋势等视角，对相关的研究方向和关键词进行了解读。特别是从学科基础层面和具体应用层面两个维度，对D0509下设的六大研究方向，以及各方向的关键词进行分析，有助于申请人和评审专家根据自己的学术背景准确挑选关键词，以利于申请书的精准评审。本文可以为科研人员在基金申请过程中关键词的选择提供参考。

Research Directions and Keywords under the Secondary Application Codes of the Atmospheric Sciences Discipline of the National Natural Science Foundation of China: D0509 Atmospheric Observation,Remote Sensing and Detection Technology and Methods

The National Natural Science Foundation of China has actively pursued reform work, with “optimizing the layout of disciplines” as one of the primary tasks, and the adjustment of discipline application codes is an important component and entry point of this task. This work is being done in order to adapt to the new round of scientific and technological development. From 2019 to 2022, the Department of Atmospheric Sciences of the National Natural Science Foundation of China reformed the secondary application codes. D0509, “Atmospheric observation, remote sensing, and detection technologies and methods,” incorporated all atmospheric observation research. The D0509 is defined as “supporting technologies” to differentiate it from “sub-disciplines” and “development areas” of science. At present, D0509 has designed six research avenues from two perspectives, based on the basic level of the discipline and the specific application level, with approximately 20 keywords for each direction. This article describes the reforming process of the D0509 code and interprets the research directions and keywords from the perspectives of the importance, connotation, extension, and development trend of atmospheric observation, remote sensing, and detection technologies and methods. It helps applicants and review experts accurately select keywords according to their academic backgrounds and facilitates the accurate matching of proper reviewers to each proposal.
