WebLee et al. (2011b) recommend weighting the OMI values with the inverse area of the swath pixel to give a higher weight to the near-nadir data, this was not done in the current work. OMI has suf-fered from a partial blockage of its ﬁeld of view leading to row anomalies. In order to have a consistent record, we limit the WebNO2 columns over the Mediterranean, sea grid-boxes only, vided. Comparing the emission totals we find that at least seasonal mean, JJA 2006: (a) as retrieved from the OMI satellite, 20% of the emissions in the Mediterranean account for the original resolution, (b) satellite data interpolated on the model grid domestic traffic. timer in mit app inventor
