AB: The standard nitrogen dioxide (NO₂) data product, produced from measurements by the Ozone Monitoring Instrument (OMI), are publicly available online from the NASA GES-DISC facility. Important data fields include total and tropospheric column densities, as well as collocated data for cloud fraction and cloud top height, surface albedo and snow/ice coverage, at the resolution of the OMI instrument (12 km × 26 km, at nadir). The retrieved NO₂ data have been validated, principally under clear-sky conditions. The first public-release version has been available since September 2006. An improved version of the data product, which includes a number of new data fields, and improved estimates of the retrieval uncertainties will be released by the end of 2007. This talk will describe the standard NO₂ data product, including details that are essential for the use of the data for air quality studies. We will also describe the principal improvements with the new version of the data product.
