We provide monthly data for sea ice production (m/month) and occurrence rates of thin ice and active frazil for all sea ice-covered oceans in the Northern Hemisphere during the winters (September-May) of 2002/2003 to 2010/2011. The sea ice data are mapped onto the National Snow and Ice Data Center (NSIDC) polar stereographic projection with a grid spacing of 6.25 km. For information on how to access the geolocation data, please see the website of NSIDC (https://nsidc.org/data/user-resources/help-center/guide-nsidcs-polar-stereographic-projection). The monthly occurrence rates of thin ice and active frazil are calculated by using daily thin ice type retrieved from AMSR-E microwave data. The estimation of ice production is based on a heat flux calculation that uses ERA5 reanalysis product and AMSR-E ice thickness improved by taking account of the ice type. The calculation period of the occurrence rates includes the sea ice melt season, in which the accuracy of thin ice detection is considerably reduced. When thin ice is detected in the melt season, pixels with a positive net heat flux are excluded from the judgment of thin ice and active frazil because they are not considered to be newly formed ice.
