Network for the Detection of Atmospheric Composition Change

The international Network for the Detection of Atmospheric Composition Change (NDACC) is composed of more than 70 globally distributed, ground-based, remote-sensing research stations with more than 160 currently active instruments. The repository is intended to, among other objectives, detect changes and trends in atmospheric composition and to understand their impacts on the mesosphere, stratosphere, and troposphere; to provide critical data sets to help fill gaps in satellite observations; and to provide validation and development support for atmospheric models.国际大气成分变化监测网络（International Network for the Detection of Atmospheric Composition Change，简称NDACC）由70余个全球布设的地基遥感观测研究站构成，当前搭载160余台正在运行的观测仪器。该网络的数据存储库旨在兼顾其他相关研究目标的同时，实现以下核心功能：监测大气成分的变化与趋势，解析其对中间层、平流层及对流层的影响；为填补卫星观测的空白提供关键数据集；并为大气模式的验证与研发提供支撑。
