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.

Sea Ice Update July 8 2014 -Antarctica 2014 Has Most Daily Records Ever!

A quick update for sea ice extent for day 188 of 2014

  • Global Sea Ice Extent is 33,000 sq km above the 1981-2010 mean. That is ranked 16 for the day.

This is a chart of the number of daily records and 2nd,3rd etc.  2014 now has more daily records (First) than any other year.

2014 is in 3rd place for top 5 … but it is only July 8. 180 days to go in the year.

There are no daily records from before 2007!
