An incredible turn of events in Arctic Ice extent reporting in the last five days.\u00a0 As the chart above shows, it is not unusual in August to have sharp downturns in ice extents.\u00a0 However, the 2023 drop is unprecedented and looks suspiciously like an adjustment to bring MASIE in line with SII.\u00a0 Note that for 25 days, MASIE showed much more ice than SII, ranging as much as +622k km2 on August 1 and +572k km2 on day 222. Moreover, those two days were in surplus to MASIE 17 year average:\u00a0 +46K km2, and + 265k km2 respectively.<\/p>\n\n\n\n

Then on day 223 MASIE dropped 466k km2, unprecendented for a single day.\u00a0 \u00a0And further declines resulted a five day total loss exceeding 1 Wadham, 1.05M km2.\u00a0 In just five days, a surplus of\u00a0 +265k turned into a deficit of -448k.\u00a0 And MASIE is now 170k lower than SII.\u00a0<\/p>\n\n\n\n

I have asked for an explanation and am awaiting a reply from NSIDC.<\/p>\n\n\n\n

The table for day 227 shows a distribution of ice extent across the Arctic regions, in comparison to 17 year average and 2007.  2023 was 448k km2 below average, or 8% of total extent.<\/p>\n\n\n\n
