Tag: Global Sea Ice Extent

I have no idea what is the right data. The NSIDC says:

“The daily sea ice extent images are sporadically displaying erroneous data. NSIDC is investigating with our satellite data providers.”

After they fix the satellite I’ll have to decide whether to snooth the data or leave it as is. Maybe I’ll have a poll!

NSIDC has this message on their website.

UPDATE: NSIDC has this message on their website.

I think somebody is just messing with us.

Another day… more strange jumps in the data. Today it is the Antarctic. I have my doubts about a 2,500,000 sq km jump in one day.

The satellite image seems to have found large areas of imaginary something.

Another day… still more strange jumps in the data. Today it is the Arctic.

Another day… more strange jumps in the data. Today it is the Arctic. I have my doubts about a 1,000,000 sq km jump in one day.

Day 96 saw the NSIDC publish two sets of data for Antarctica. One was a sudden huge jump and the later one was a big drop.

Here is day 97:

UPDATE 2: They updated the data, at 3:22 down to 5.786 (which is a 300,000 sq km drop from the day before. Not likely.

On day 96 the Antarctic sea ice extent took an unlikely jump from 6.082 million sq km to 7.959.

Sometimes they correct it the next day. Sometimes they don’t.

UPDATE: The “stuttering” in the daily Antarctic image. (Thanks AZ1971)
