2021年11月哨兵5p卫星2级甲烷离线产品（L2__CH4___ OFFL）

本数据集为2021年11月哨兵5p卫星2级甲烷离线产品合集；数据来源于欧洲航天局发射的用于温室气体和痕量气体监测的Sentinel-5p卫星的TROPOMI传感器，该卫星可以实现全球每日一次重访。为了方便国内用户的访问，本数据集由国家对地观测科学数据中心团队负责整理和维护，将不同产品按月形成压缩数据集，用于数据分发和服务。

This dataset is a collection of Level 2 off-line methane products from the Sentinel-5P satellite in November 2021. The data is sourced from the TROPOMI sensor aboard the Sentinel-5P satellite, which was launched by the European Space Agency (ESA) for monitoring greenhouse gases and trace gases, and enables global revisit once per day. To facilitate access for domestic users, this dataset is organized and maintained by the team of the National Earth Observation Science Data Center, which packages various products into compressed monthly datasets for data distribution and services.
