A couple notes that may help sort out problems with l2gen:
The benchmark script is useful as a reference and uses a small data set that is easy for others to obtain.
If you get a netcdf output file, it should include lots of detail including the l2gen command line. This has been useful when debugging batch processing scripts, etc.

Here is an example of using L1A files as a list --
1) multilevel_processor-forum-L1A.par looks like that
[main]
ifile=/Users/USERNAME/Scenes/MODIS_AQUA/forum/ifile_forum_11_02_23.txt
use_ancillary=1
overwrite=1
[l2gen]
aer_opt=-3
2) ifile_forum_11_02_23.txt looks like this --
/Users/USERNAME/Scenes/MODIS_AQUA/forum/A2023278044500.L1A_LAC
/Users/USERNAME/Scenes/MODIS_AQUA/forum/A2023287060500.L1A_LAC
/Users/USERNAME/Scenes/MODIS_AQUA/forum/A2023289005500.L1A_LAC
3)
Code: Select all
multilevel_processor par=multilevel_processor-forum-L1A.par

Here is an example of using L1B files as a list --
1) multilevel_processor-forum-L1B.par looks like this --
[main]
ifile=/Users/USERNAME/Scenes/MODIS_AQUA/forum/ifile_L1B_forum_11_02_23.txt

2) ifile_L1B_forum_11_02_23.txt looks like this

/Users/USERNAME/Scenes/MODIS_AQUA/forum/AQUA_MODIS.20231014T060500.L1B.hdf
3) Make sure the following files exsit
