SII v.4<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NSDIC acknowledged my query regarding the SII (Sea Ice Index) dataset. While awaiting an explanation I investigated further. My last download of the SII Daily Arctic Ice Extents was on July 30, meaning that the most recent data in that file was day 210, July 29. The header on that file was Sea_Ice_Index_Daily_Extent_G02135_v3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then on August 1, the downloaded file had the heading Sea_Ice_Index_Daily_Extent_G02135_v4. So it appears that these are now the values from a new version of SII. As I wrote in my query, since March 14 all of the values for Arctic Ice Extents are lower in this new record. The graph above shows the implications for August as an example of estimates from SIIv.4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the past, SIIv.3 tracked MASIE with slightly lower values.&nbsp; But with v.4, larger monthly average deficits to MASIE were reported in July 2025 ( -282k km2) and in August (-440k km2).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The change started in January 2025 and will be the basis for future reporting.&nbsp; The logic for this is presented in this document:&nbsp;<a href=\"https:\/\/nsidc.org\/sites\/default\/files\/documents\/technical-reference\/nsidc-special-report-28.pdf\"><strong>Sea Ice Index Version 4 Analysis<\/strong><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>In June 2025, NSIDC was informed that access to data from the Special Sensor Microwave<\/em><br><em>Imager\/Sounder (SSMIS) onboard the Defense Meteorological Satellite Program (DMSP)<\/em><br><em>satellites would end on July 31 (NSIDC, 2025).
