Abstract
Aerosol monitoring from space has been performed at mesoscale, for over two decades. Latest satellite aerosol products offer global daily coverage and a typical spatial resolution of 10 km × 10 km. A new synergy algorithm has been recently developed, to retrieve aerosol properties in higher spatial resolution, which may improve the study of aerosols at local scale, increasing the potential of Earth Observation to support local level air quality studies. The algorithm combines both spectral and angular information provided by MERIS and AATSR sensors, respectively. In the present study, the MERIS/AATSR synergy algorithm is validated by comparing the retrieved Aerosol Optical Thickness (AOT) with the respective AOT values observed at AERONET stations located in urban regions globally. AATSR, MERIS and AERONET data for the period August–September 2011 were analyzed. Comparisons with the respective AOT spatial distributions retrieved from MODIS aerosol product were also performed for the broader area of Athens. Results indicate that the retrieved AOT is in good agreement with the corresponding station measurements.
