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.

Prior to 2021-07-01 only two parameters were available, 1. Total Aerosol Optical Depth at 550 nm surface 2. Particulate matter d < 25 um surface Note that system:time_start refers to forecast time.
