Hi,

I get this weird error when I try to load a sea ice concentration file from NSIDC: Error: band does not contain integer pixels

I am using the Climate Data Record product for ice concentration, data set G02202 https://nsidc.org/data/g02202

They recently created a new Version 4. I only get this error when using Version 4. Version 3 worked fine. There is nothing obvious in the headers of the file. IDL, Panoply, etc. can read it fine...

For example file: ftp://sidads.colorado.edu/pub/DATASETS/ ... _v04r00.nc

This happens in SeaDAS 8 as well as SeaDAS 7.5 and gpt. NSIDC doesn't know either why it wouldn't load.

Thanks!

Thanks for reporting the bug.

The new version of the NSIDC sea ice file has 3D arrays, but one dimension is unity. It seems that we need a new reader for it.

We'll work on it.

The version 3 format data are still available as well as v4.

Thanks for looking into it!

Version 3 only goes through 2020...

OK we are using the NRT data and get the version 3 here:

https://n5eil01u.ecs.nsidc.org/PM/NSIDC ... _nrt_s.bin

I am the user representative for this data set at NSIDC. I just wanted to add that version 3 of the NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration data set will soon no longer be available. Public access to version 3 will no longer be available after 18 February 2022. There are a lot of differences between version 3 and version 4, so in general we recommend using the latest version of the data, version 4: https://nsidc.org/data/g02202/versions/4.
