dc.description.abstractWe review the standard nitrogen dioxide ( NO₂ ) data product (Version 1.0.), which is based on measurements made in the spectral region 415–465 nm by the Ozone Monitoring Instrument (OMI) on the NASA Earth Observing System-Aura satellite. A number of ground- and aircraft-based measurements have been used to validate the data product's three principal quantities: stratospheric, tropospheric, and total NO₂ column densities under nearly or completely cloud-free conditions. The validation of OMI NO₂ is complicated by a number of factors, the greatest of which is that the OMI observations effectively average the NO₂ over its field of view (minimum 340 km ²), while a ground-based instrument samples at a single point. The tropospheric NO₂ field is often very inhomogeneous, varying significantly over tens to hundreds of meters, and ranges from <10 ¹⁵ cm ⁻² over remote, rural areas to >10 ¹⁶ cm ⁻² over urban and industrial areas. Because of OMI's areal averaging, when validation measurements are made near NO₂ sources the OMI measurements are expected to underestimate the ground-based, and this is indeed seen. Further, we use several different instruments, both new and mature, which might give inconsistent NO₂ amounts; the correlations between nearby instruments is 0.8–0.9. Finally, many of the validation data sets are quite small and span a very short length of time; this limits the statistical conclusions that can be drawn from them. Despite these factors, good agreement is generally seen between the OMI and ground-based measurements, with OMI stratospheric NO₂ underestimated by about 14% and total and tropospheric columns underestimated by 15–30%. Typical correlations between OMI NO₂ and ground-based measurements are generally >0.6.en_US
