Abstract

Tropospheric NO₂ columns derived from the data products of the Global Ozone Monitoring Experiment (GOME), deployed on the ESA ERS-2 satellite, have been compared with model calculations from two global three-dimensional chemistry transport models, IMAGES and MOZART. The main objectives of the study are an analysis of the tropospheric NO₂ data derived from satellite measurements, an interpretation of it and evaluation of its quality using global models, and an estimation the role of NO₂ in radiative forcing. The measured and modeled NO₂ columns show similar spatial and seasonal patterns, with large tropospheric column amounts over industrialized areas and small column amounts over remote areas. The comparison of the absolute values of the measured and modeled tropospheric column amounts are particularly dependent upon uncertainties in the derivation of the tropospheric NO₂ columns from GOME and the difficulty of modeling the boundary layer in global models, both of which are discussed below. The measured tropospheric column amounts derived from GOME data are of the same order as those calculated by the MOZART model over the industrialized areas of the United States and Europe, but a factor of 2-3 larger for Asia. The modeled tropospheric NO₂ columns from MOZART as well as the column amounts measured by GOME are in good agreement with NO₂ columns derived from observed NO₂ mixing ratios in the boundary layer in eastern North America. The comparison of the models to the GOME data illustrates the degree to which present models reproduce the hot spots seen in the GOME data. The radiative forcing of NO₂ has been estimated from the calculated tropospheric NO₂ columns. The local maxima in the radiative forcing of tropospheric NO₂ for cloud-free conditions over the eastern United States and western Europe represent 0.1-0.15 W m^-2, while values of 0.04-0.1 W m^- are estimated on a continental scale in these regions, of the same order of magnitude as the forcing of N₂O and somewhat smaller than the regional forcing of tropospheric ozone. The globally averaged radiative forcing of tropospheric NO₂ is negligible, ∼0.005 W m^-2.
