NPP Data Affected By Solar/Lunar Eclipses

The VIIRS products generated at IDPS and Land PEATE using the sensor data acquired during the Solar eclipses may have quality related problems. Since there is no automated process implemented at IDPS or at Land PEATE to identify the VIIRS overpass intersecting the Solar eclipse, the affected L1B SDR granules could not be removed from the daily processing of VIIRS data. The anomaly in the TOA irradiance and reflectance is propagated to the downstream VIIRS EDRs and IPs. Users are advised to refer to the following table for possible data anomaly in the product due to eclipse. This listing contains eclipse days highly visible in the global browse images of daily Surface Reflectance IP. The affected area appears dark in the global browse. Other eclipses may have had more subtle effects. The location of the data most strongly affected by each eclipse is noted for each one. Click on the link to see the global browse of the surface reflectance for the day and also the high resolution browse of the affected spatial subset. The exact trajectory of each of these eclipses can be found at the NASA ECLIPSE WEB SITE.
