The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is pleased to announce the release of the Polar Stereographic Valid Ice Masks Derived from National Ice Center Monthly Sea Ice Climatologies data set. These valid ice masks provide a way to remove spurious ice caused by residual weather effects and land spillover in passive microwave data, and are derived from the National Ice Center Arctic Sea Ice Charts and Climatologies data.
