NiPR-JAXA sea ice extent tracker based on AMSR2 ice concentration. An interactive version is available on their website.

Sea-ice extent for Northern Hemisphere from the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF, osisaf.met.no).

Ice Time Series plots are from NSIDC

NiPR-JAXA sea ice extent trend for the September minimum. More plots are available from the
National Institute of Polar Research (NIPR) Arctic Data archive System (ADS).

JAXA's composite image product with sea ice concentration, sea surface temperature, and snow depth on land. From AMSR2 data.
More plots are available from the National Institute of Polar Research (NIPR) Arctic Data archive System (ADS)

This is a daily composite of sea ice concentration from S-NPP VIIRS orbits. It is generally 5 days old.
This is a NOAA "enterprise" algorithm; it is not the NOAA operational algorithm distributed through CLASS.
It is produced by the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and NOAA at the
University of Wisconsin-Madison.
Caution: There are sometimes issues with the cloud mask that are seen in the ice concentration plots.

This is NSIDC's Ice extent product.

NSIDC produces MASIE (may-zee) in cooperation with the U.S. National Ice Center (NIC). MASIE relies on data
from the Interactive Multisensor Snow and Ice Mapping System (IMS) that runs at the NIC. The IMS product uses
several satellite data sources including passive microwave, but it is also based on visual analysis and other data
sources and undergoes a form of manual data fusion.

NiPR-JAXA sea ice thickness. More information is available on their website

28-day composite of sea ice thickness based on CryoSat data from the CryoSat Operational Polar Monitoring (CPOM) group
and the European Space Agency (ESA). CPOM's CryoSat sea ice thickness website, with additional information and access to
the data, is http://www.cpom.ucl.ac.uk/csopr/seaice.html. 14-day and 2-day composites are also available.

Sea ice thickness from ESA's Soil Moisture Ocean Salinity (SMOS) satellite.Important: The maximum retrievable ice
thickness with SMOS is about 1 m. Additional information and data are available from the Universität Hamburg.

NiPR-JAXA sea ice age. This product is calculated every day but with a 6-day lag. More information is available
on their website.

NiPR-JAXA sea ice age. This product is calculated every day but with a 6-day lag. More information is available

OSI SAF Ice Drift is the low resolution sea ice drift product from the EUMETSAT Ocean & Sea Ice Satellite Application Facility (OSI SAF).
It is based on SSMIS and ASCAT data.

NiPR-JAXA sea ice drift. More information is available on their website.

This is a daily composite of sea ice surface (skin) temperature (IST) from S-NPP VIIRS orbits. It is generally 5 days
old. This is a NOAA "enterprise" algorithm; it is not the NOAA operational algorithm distributed through CLASS.
It is produced by the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and NOAA at the University
of Wisconsin-Madison. Caution: There are sometimes issues with the cloud mask that are seen in the IST plots.
