Welcome to the NERSC Arctic Sea Ice Observation System.
NERSC has processed daily passive microwave remote sensing data of sea ice from the Arctic since they first became available in 1978 using the NERSC developed NORSEX algorithm.
Due to funding restrictions in US, support for this data from NSIDC is reduced to BASIC, se info here.
Some missing data may occur in periods, showing strange results - see here
