This work was performed in the framework of the PEFYKA project within the KRIPIS Action of the General Secretariat for Research and Technology. The project is funded by Greece and the European Regional Development Fund of the European Union under the NSRF and the O.P. Competitiveness and Entrepreneurship (Ref: 10575-20/09/2013 ). Anton Beloconi is grateful to the MathMods (Mathematical Modeling in Engineering) program for partially funding this work through a scholarship sponsored by the EACEA under the project No. 2008-0100. Yiannis Kamarianakis was partially supported by the National Science Foundation under Award DMS-1419593 . The authors are grateful to three anonymous reviewers for their constructive comments, to the European Space Agency for providing MERIS and AATSR data based on the Category-1 project (ID: 12018) and to the London Air Quality Monitoring Network for providing the PM10 and PM2.5 measurements.

N2 - This study evaluates alternative spatio-temporal approaches for quantitative estimation of daily mean Particulate Matter (PM) concentrations. Both fine (PM2.5) and coarse (PM10) concentrations were estimated over the area of London (UK) for the 2002-2012 time period, using Aerosol Optical Thickness (AOT) derived from MERIS (Medium Resolution Imaging Spectrometer)/AATSR (Advanced Along-Track Scanning Radiometer) synergistic observations at 1. km. ×. 1 km resolution. Relative humidity, temperature and the K-Index obtained from MODIS (Moderate Resolution Imaging Spectroradiometer) sensor were used as additional predictors. High-resolution (100. m. ×. 100. m) local urban land cover and morphology datasets were incorporated in the analysis in order to capture the effects of local scale emissions and sequestration. Spatial (2-D) and spatio-temporal (3-D) kriging were applied to in situ urban PM measurements to investigate their association with satellite-derived AOT while accounting for differences in spatial support. Linear mixed-effects models with day-specific and site-specific random intercepts and slopes were estimated to associate satellite-derived products with kriged PM concentration and their predictive performance was evaluated.
