MASIE Arctic Ice Extent as of 2014-194

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.
