Striping in some Terra MODIS L2 Surface Reflectance Granules

October 24, 2010

The MODIS Science team informed us that they have recently identified certain Terra MODIS L2 land surface reflectance granules that contain severe striping in high reflectance values, which are retrieved in alternate scans of 10 Kms. This effect is traceable to the striping present in band-3 of the L1B (MOD02IKM) product, which is used to retrieve the aerosol optical thickness in the surface reflectance. Additional information, including some examples, is available from the following URL: http://landweb.nascom.nasa.gov/cgi-bin/QA_WWW/displayCase.cgi?esdt=MOD09&caseNum=SD_MOD09_10284&caseLocation=cases_data

The MODIS Science team is investigating this issue, and we will provide an update on this subject as more information is available.
