An inter-comparison study of the aerosol optical thickness (AOT) at 0.55 μm retrieved using different satellite instruments and algorithms based on the analysis of backscattered solar light is presented for a single scene over central Europe on October 13th, 2005. For the first time comparisons have been performed for as many as six instruments on multiple(More)
The Global Imager (GLI) onboard ADEOS-2 is the first medium-resolution Earth observation satellite sensor that is able to combine measurements from the near-UV to the IR wavelength region. This work investigates a newly available channel in the near-UV to retrieve the optical thickness and single-scattering albedo of aerosols. Due to the low reflectivity of(More)
Besides pre-launch and on-board calibration, the method of vicariously calibrating space sensors became a reliable tool for sensor calibration. One possibility of vicarious calibration is to inter-calibrate sensors aboard different satellite platforms directly. This leads to a better understanding of differences in global data sets, which are produced(More)
We evaluate the potential of satellite aerosol data for monitoring national and regional air quality in Austria. This work was performed within the framework of the GSE project PROMOTE, and applies aerosol data derived from MERIS onboard ENVISAT. MERIS aerosol data, which are based on the ESA standard algorithm, are provided with a time delay between data(More)
