Description

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, 1. Total Aerosol Optical Depth at 550nm surface 2. Particulate matter d < 25 um surface Note that system:time_start refers to forecast time.
