Sentinel-5P Level 2

This data set consists of observations from the Sentinel-5 Precursor (Sentinel-5P) satellite of the European Commission’s Copernicus Earth Observation Programme. Sentinel-5P is a polar orbiting satellite that completes 14 orbits of the Earth a day. It carries the TROPOspheric Monitoring Instrument (TROPOMI) which is a spectrometer that senses ultraviolet (UV), visible (VIS), near (NIR) and short wave infrared (SWIR) to monitor ozone, methane, formaldehyde, aerosol, carbon monoxide, nitrogen dioxide and sulphur dioxide in the atmosphere. The satellite was launched in October 2017 and entered routine operational phase in March 2019. Data is available from July 2018 onwards.

本数据集收录了欧洲委员会哥白尼地球观测计划（Copernicus Earth Observation Programme）的哨兵-5前驱卫星（Sentinel-5 Precursor，简称Sentinel-5P）的观测数据。哨兵-5P是一颗极地轨道卫星，每日环绕地球14圈。卫星配备有用于监测大气中臭氧、甲烷、甲醛、气溶胶、一氧化碳、二氧化氮和二氧化硫的TROPOspheric Monitoring Instrument（简称TROPOMI）光谱仪，该仪器能够感知紫外（UV）、可见（VIS）、近红外（NIR）和短波红外（SWIR）波段。哨兵-5P卫星于2017年10月发射升空，并于2019年3月进入常规运行阶段。数据自2018年7月起可供使用。
