MODIS Cloud Cover Anomaly

An anomaly occurred in the processing of the MOD35 and MYD35 cloud products, which are used in the creation of MODIS snow and sea ice products, causing data appearing to have more cloud cover than what actually existed. The list below summarizes affected dates. Data for 09-19 July 2003 are being reprocessed and will eventually replace the original products. The MODIS science team is evaluating the science impact of the problem, to determine which other days should be reprocessed.

This page will be continually updated with reprocessing dates for affected data. Please check back soon for updates.
