MASIE - Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH)
NOTICE: The input data for MASIE that comes from the IMS Daily Northern Hemisphere Snow and Ice Analysis product created at the National Ice Center (NIC) contains corrupted data for 13 July 2016. NIC is working to reprocess the bad data, but they will not have this done immediately. In the meantime, the bad day of data has been removed from the MASIE time series. The IMS product is a near-real-time operational data set, and as is the rule with operational centers, gaps in production can occur without warning. For a complete list of all gaps in the MASIE time series see the file masie-missing-files-list.txt. Normal forward processing should resume tomorrow. Contact NSIDC User Services with any questions.
