Google Earth engine (GEE) -- Copernicus atmosphere monitoring (CAMs) global aerosol AOI near real-time observation data set

​

Copernican atmospheric monitoring service (CAMS) Global near real time observation data set

The Copernicus atmospheric monitoring service provides the ability to continuously monitor the earth's atmospheric composition on a global and regional scale . The main global near real time production system is a data assimilation and prediction suite , Provide aerosols and chemical compounds twice a day for a period of 5 Day forecast , These are all part of the chemical scheme .

stay 2021-07-01 Before , Only two parameters are available ,1. 550 nm Total aerosol optical depth of the surface 2. particulate matter d < 25 um The surface of the Be careful system:time_start Is the forecast time .
