Aerosol Robotic Network

Project Description
AERONET (AErosol RObotic NETwork) is an optical ground based aerosol
monitoring network and data archive supported by NASA's Earth
Observing System and expanded by federation with many non-NASA
institutions. The network hardware consists of identical automatic
sun-sky scanning spectral radiometers owned by national agencies and
universities. AERONET sites are located around the world. Data is
