Arctic sea ice / Re: 2019 sea ice area and extent data

« on: June 12, 2019, 07:21:01 PM »

Sambucco, and Rich, and anyone else interested in the NSIDC numbers, you can download the spreadsheet and look at the actual data.

I used to download that every day to look at the raw data. It's really easy to add a formula to calculate the daily extent drop, 5-day average drop or whatever.

Thank you, Oren, but I can't have access to this FTP. You still confirm there is only five days average for area ?

Alphabet Hotel, it is indeed really easy to calculate an average from daily data. What is less easy is to find individual daily datas from 5 days average. What I tried to do.
I'm not mathematician, maybe there is a way to calculate it precisely ?

The link has an error.  It should be ftp:// which it shows in the text but the hyperlink has ftp//

Arctic sea ice / Re: The 2018 melting season

10 day forecast. (Max temperature.)

Personally I'd be happier if we kept this thread closer to the observations. I can wait ten days to see what happened, whereas looking forward ten days from now is a total crapshoot (especially with GFS).

Is GFS totally at fault ? I've just scrolled through cci-reanalyzer using the hourly forecast slider and I have seen nothing to match the image posted by Telihod. It all looked very ordinary to me - warmth and cold moving anti-clockwise around and no massive anomalies.

Slightly OT, but the GFS has a hurricane in the Gulf of Mexico in about 12 days...Not sure how the verification scores line up in the Arctic versus globally, but that model has issues.

CMC keeps the low sub 980 for at least the next ten days.  How do the verification scores line up for this model vs the Euro/GFS?
