NSIDC has determined that the browse images for this data set contain errors. The science granules are unaffected. We have removed the browse images until the data provider corrects the problem and resends new files. Although we are currently unable to estimate when the reprocessing will be complete, NSIDC will make the new images available as soon as they are delivered.
