Antarctic Sea Ice Extent July 24 2014 – Smashes Daily Record By 240,000 sq km

Antarctic Sea Ice Extent is 1,102,000 sq km above the 1981-2010 mean

That smashes the previous daily record by 240,000 sq km. And is also the 126th daily record for the year.

Antarctic Sea Ice Extent For This Day Up 1.4 million sq km from 2002

There is some claims that possibly/maybe a “sensor error” caused a small overestimation of sea ice extent in the Antarctic since 1991.

From what I understand the paper is atrocious. More importantly, this is what the sea ice extent for this day looks like:

Sea Ice Update July 14 2014 – Antarctica Sensor/Processing Error

UPDATE: A new set of data has been published. But there is still a value in the missing column. 0.01597 million sq km.

The updated graph:

2014_July_14_Antarctica_Sensor_Error_2

I have been a bit worried about the deep deep dive in Antarctica Sea Ice Extent.

It appears to be a processing or sensor error. As of today the NSIDC data confirms it.

The table of data on the right of this image is the last 5 days. The data does have a value in the Missing column – 1.97873 million sq km.

The Missing column is usually empty. Sometimes it takes NSIDC a couple of days to sort things out.
