September daily extents are now fully reported and the 2022 September monthly results can be compared with those of the previous 15 years. MASIE showed 2022 at 5.1M km2 and SII was close behind, reaching 4.9M for the month. Analysis below shows that the 2022 Minimum was ~ 300k km2 higher than the 15 year average, and 1.2 Wadhams (1 M km2) more than 2007. The 16 yr. trendlines are virtually flat and matching the averages for the period.
In June, 4.6M km2 was the median estimate for the September monthly average extent from the SIPN (Sea Ice Prediction Network) who use the reports from SII (Sea Ice Index), the NASA team satellite product from passive microwave sensors. The SII actual ice extent was 300k km2 higher than estimated.
The graph below shows September comparisons through day 273 (Sept. 30).
Note that MASIE was higher than average throughout September, with…
