Hi,
Thanks for your time on my query.
Yes, It is Aura (OMI L2) files. Initially, the files were in .he5 but I converted them into .nc using the NCL converter. The main issue is coming from the dimension size. Each file has different dimension sizes and that’s why I can not merge/concatenate all the files into one file. I tried with NCO. It can merge the files with NCO, but it is possible only if the initial file has a lower/or lowest dimension size compared to the other files. But doing this also changed the grid position.
the dimension such as
nTimes_Aerosol_NearUV_Swath = 607 ;
varies with files. So, I guess, either I need to fix these dimensions sizes first OR I need to make all the files into a rectangular grid projection then I can easily work on it.
Regarding L4, I don’t find L4 data. Also, as you know, L2 is considered of good quality with higher resolution data. So I guess, I have to be strict on L2 data only.
Thanks
