Duplicating previous announced material. Thought it may be interesting to know NSIDC is working to keep us happy.
It's offical now.
Received a new E-Mail "alert" from NSIDC User Services: nsidc( a- t )kryos.colorado.edu
Announcing a NEW Daily Extent Archive in .CSV format, can be used in a SpreadSheet,
which Neven had already placed on Daily Graphs Page at
https://sites.google.com/site/arcticseaicegraphs/
After following links at http://nsidc.org/data/seaice_index/ eventually get to
ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/north/daily/data/NH_seaice_extent_nrt.csv

Sea Ice Index Update Tue, Aug 14, 2012 4:02 pm
From NSIDC User Services: nsidc( a-t )kryos.colorado.edu
To
Dear colleague,
NSIDC is pleased to announce that the Sea Ice Index data archive now has daily
as well as monthly sea ice extent values for the Northern and Southern
Hemispheres. The product documentation has also been updated to include an
explanation of how these are derived and to give a clearer and complete
description of all Sea Ice Index products. The documentation now includes the
following:
-Flow charts to facilitate understanding of the data processing steps.
-Explanation on how the median edge position is determined and why it is used.
The median edge is the pink line on the monthly extent images and the orange
line on the daily extent images.
-Clearer explanation of coverage and resolution.
-More information on data accuracy.
-Explanation on how to use the Browse Image Spreadsheet Tool (BIST) to quickly
compare images from past years.
-A short section on how the product has evolved, from 2002 to 2012.
To access the data and the new documentation, see the Sea Ice Index Web site at:
http://nsidc.org/data/seaice_index/
If you have questions, please contact NSIDC's User Services Office at

I'm going to give this data set more of the attention it deserves next year. I'm so used to manually updating IJIS SIE and CT SIA that I couldn't fit this one in.
It's great that NSIDC has made daily data available. Anthony Watts complained about it many times, but doesn't seem to have the time yet to announce this to his audience and thank the NSIDC publicly.

79 Fjords Glacier,
Just studied some up2date radar images from Joekelbugt, and it looks like 79 got a calving potential of + 100 km2?

Neven, pre 2011 values are also available at:
ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/north/daily/data/NH_seaice_extent_final.csv

It is the best if you just remove file name and use directory. There are 3 files in there:
- Current data (nrt.csv) file
- Climatology data (climatology_1979-2000.csv)
- Historical data (final.csv)

Thank you Jack and Neven for making this info public. In the interests of sparing the hosting Organization some spam, perhaps you could slightly 'transmogrify' the -at- symbol within the email addy above, just to throw off the spambots
please feel free to delete this comment as well!
Cheers,
Lodger

Lodger,
Transmorgified the e-mail addy's above. Needed to know how to EDIT a post, first time and it worked. Kind of been useless for the blog lately - used to try to do some animations, but now Neven is always a step ahead of me, maybe someday I will find something positive that's not a duplication.
Because the link(s) were not activated properly, it's doubtful any "spambots" picked the addy out, because 99% of them are coded to pick up on the mailto: scheme of the HTML Anchor Tag surrounding
mailto:[email protected]
Delete this most - no way - it's what a group or team is about - you're relevant, enjoyable, and useful for me read your comments.
Cheers,
JackT
