I tested the code on my system (Mac). For example,
>> ls /private/var/folders/jq/wx1hzy713dj_408tpm5fck040000gn/T/cosmic2013/001/cosmic2013/scnLv1/2013.001/

(and more)
I did not test it on Windows (I am not sure I have a functioning Windows MATLAB installed at the moment.)

It's been a 20 minutes that Matlab is busy to only extract two day 1 and 2. The folder 1 is still empty. How could it be possible to not work in Windows? I have to extract 365 days.

Dear Walter,
It works. For folder 1 completely downloaded all data. Thank you very much. Only problem is very slow and gets busy for ~25min for one file. Is there any way to improve it?

You are mostly being limited by the speed of your internet connection.
If you change the assignment
td = tempdir();
you could change the download directory to an SSD if you have one. That could potentially make the untar step faster.

Oh, I see! Yes the internet connection is not very good.
SSD means external memory? Would it be possible to download it all files in it instead of C? I do not know how to change it. Wouldyou please let me know how to change the path to the current folder or specifically in the external memory?
