Data collected by NASA’s Ozone Monitoring Instrument (OMI) are integral for distinguishing between aerosol types, such as smoke, dust, and sulfates, among other investigations. Explore OMI datasets and learn more about relevant data tools.
Gaps in the OMI data are a result of anomalous levels of incident radiation on the detector charge-coupled device (CCD) at all wavelengths for particular viewing directions. The first appearance of the row anomaly is on June 25, 2007. At that time, it appeared only in rows 53 and 54 (zero-based). From May 11, 2008, cross-track scenes 37-41 (0-based) are affected as well.
In January 2009 the range of rows extended to 27-44, while the original rows 53 and 54 remain affected. Since then the behavior of the row anomaly has remained dynamic. Which rows are affected and to what extent varies with time. Because the row anomaly is caused by anomalous incident radiation on the OMI CCD, it affects the quality of the Level-1B products, and consequently all retrieved quantities of Level-2 and Level-3 data.
