You sceptic you. https://wattsupwiththat.com/2016/09/...-days-earlier/ Thanks Lawrence! I asked as many knowledgeable people as I knew who had an interest in sea ice to look at this data and see if I was going mad or just picking up the wrong data, but apart from Alistair no one replied. I sent that link in desperation, and although he never replied personally he published it. A mention on his site can certainly bring a massive increase in the stats for your blogs, but all I want to know is just what's going on! |

By the way Bruce is this that change in DATA reflected on the Northern Hemisphere Sea Ice Anomaly data http://arctic.atmos.uiuc.edu/cryosph...aly.arctic.png Or have I got hold of the wrong end of the stick |

Isn't the explanation there in black and white on the NSIDC site, ie:
'NSIDC produces the daily extent image and graph using a five-day trailing mean. Please note, the values provided are the individual daily values, not the five-day average values that NSIDC displays for its daily extent image and graph' All you have to do is to click the 'About the data' link. |

So I'm reading the cart correctly its just now if its some artefact. a simple data mistake. |

The data is correct. The statement about it may be a mistake or it hasn't been made clear that they quote the rolling mean. Either way it would be nice to see a cooling trend for a change, especially after last December's apology of a winter month!

Thanks John that explains the difference between the news articles and the raw daily values! And using a trailing mean rather than a centred mean would explain why it occurred 3 days later. But why use a five day moving average to ascertain when the minimum extent has been reached when you have daily values? I am fairly certain this change to using a five day moving average has come in quite recently, perhaps since they started using v2 in June. |

So I'm reading the chart correctly its just now if its some artefact. a simple data mistake. An anomaly? How many of those can the University of Illinois Mean? And how do you thermomalise a million square kms? One more question: How many wet sheep do you know that have the answer for this (and b.) why didn't you ask it? Having said that I have been pondering the question of scale with this chart: Immediately preceding the earthquake or so called superquake in Japan on the 11 march 2011 http://www.woksat.info/etctcasxx/asxx11030918.html we had a three adjacent simultaneous lows in the Norwegian Sea -indicators of volcanic activity as well as of earthquakes obviously. How did they know that the three eyes was certain data? Was it an anomaly due to magic computer numbers or did they have a little man bobbing between them just checking? And did he have an hole in his arse? Or was it full of ****? |
