The TROPOMI surface DLER V2.0 product is the directionally dependent Lambertian-equivalent reflectivity (LER) of the Earth's surface as observed by TROPOMI.

The DLER product provided by S5P-PAL is the same product as available on the TEMIS website, but using a different filename.

The DLER product is based on the per-orbit scene LER products that have been generated with the SCNLER v2.1.0 processor within S5P-PAL. The scene LER products are generated based on the full timeline (5 years) of collection-3 S5P L1 data. Within S5P-PAL only the DLER product is provided to the public.

Note that scene LER products are also used as input to the AOT products as provided by S5P-PAL.

The SCNLER and DLER processors are developed and maintained by KNMI.
