The most fascinating and very useful tool they have is ‘data synergy tool’. It is really amazing for quick research and great visualization of various aerosol properties from AERONET, satellites, models, LIDARs, ozone, back trajectory, and even weather charts over any particular AERONET station.
Here is link to the synergy tool
and link to the main AERONET page
So, take some time and admire the AERONET facilities available for atmospheric aerosol research community.
Personally, I really thank the AERONET team and congrats them for their great work and services.
