The Copernicus Atmosphere Monitoring Service provides the capacity to continuously monitor the composition of the Earth’s atmosphere at global and regional scales. The main global near-real-time production system is a data assimilation and forecasting suite providing two 5-day forecasts per day for aerosols and chemical compounds that are part of the chemical scheme.
Currently only two parameters are available,
- Total Aerosol Optical Depth at 550nm surface
- Particulate matter d < 25 um surface Note that system:time_start refers to forecast time.
哥白尼大气监测服务提供了在全球和区域范围内连续监测地球大气成分的能力。主要的全球近实时生产系统是一个数据同化和预测套件,每天提供两个为期5天的气溶胶和属于化学计划的化合物的预测。
目前只有两个参数可用。
550纳米表面的总气溶胶光学深度颗粒物d<25um表面 注意,system:time_start指的是预报时间。
