Holben, 2010: Multiangle Imaging SpectroRadiometer global aerosol product assessment by comparison with the Aerosol Robotic Network
A powerful understanding of aerosol properties was made possible by the introduction of a globally acceptable ground based instrument known as Aerosol Robotic Network
Puerto Rico has a wide network of observational instruments, including ground weather stations, soil moisture sensors, a Next Generation Weather Radar (NEXRAD), twice-daily radiosonde launches, and Aerosol Robotic Network
In addition, a large Newtonian telescope optimized to 1064 nm and various optical and electronic elements have been donated through the efforts and willingness of David Whiteman from GSFC, who also supported the initiative and consolidation of a NASA Aerosol Robotic Network
(AERONET) sun photometer site in Colombia.
