Reprocessed ASI data from 2002 to Oct 2018: Version 5.4
URL: https://seaice.uni-bremen.de/sea-ice-concentration/
We have just completed reprocessing all ASI ice concentration data based on AMSR-E or AMSR2 data for the complete period, i.e., ◦ 1 June, 2002 to 4 Oct, 2011 (AMSR-E) ◦ July, 2012 to 17 Nov, 2018 (AMSR2).
The reprocessing has been done for the hemispheric maps only. i.e., Arctic/Antarctic (6.25 km grid spacing) and Arctic3125/Antarctic3125 (3.125 km grid spacing).
The tie points of the ASI algorithm were the same (version 5). However, some other details as the version of GMT (generic mapping tools) used for gridding the data and defining land masks and coast lines have changed over the years. The reprocessed data are therefore consistent with respect to all this, and have the version number 5.4. The full version number is also part of all file names ('v5.4'); the new files are stored alongside the files of previous versions 5.2 and 5.3 which just have 'v5' in their file names.
The new data being processed every day have been switched to version 5.4 on Nov. 23, 2018 which implies the mentioned change in the file names ('v5.4' instead of just 'v5')
All details about the ASI ice concentration data can be found in the the new ASI user guide
