Hi François，

I am using Polymer to process MODIS.

Firstly, I am using Seadas l2gen to convert MODIS Level 1A to Level 1C, after that generating Level 2 with polymer. The resolution of level 2 Polymer is 1000m.

Could I generate 250m resolution for level 2 with Polymer for all wavelengths?

Thank you very much.

Hello,

It should be possible to generate 250m L1C products, and then process these with Polymer. I have not tried myself though.
I suggest you pass the option "resolution=250" to l2gen in the make_L1C.py script (in the make_L1C function), and try to process the resulting L1C with Polymer. Please let me know if you encounter any issues.
Kind regards,
François

Dear François,

I tested and it worked well. I converted Level 1A to Level 1C (resolution=250) and processed L1C with polymer to obtain Level 2 - 250m.

Thank you very much for your software and supports.
