03 Source citation

ASAŞ 2024 Sustainability Report p84

Akyazı+Karapürçek single ID; extrusion+rolling, no smelting; 4yr history (2021:89988, 2022:82193, 2023:79112, 2024:68618)

04 Satellite cross-check

The TROPOMI flux-divergence catalog of Beirle et al. (2023, ESSD) lists a NOx source within 10.6 km of this plant:

0.146 ± 0.043 kg NOx/s

NOx is an activity proxy independent of operator disclosure. A catalog hit within 15 km means the plant (or its colocated captive power) is bright enough in TROPOMI to register globally. This row is in the data/beirle_match_audit_grade.csv join used by iz-1 v0.1.1+.

05 Hyperspectral coverage

3 EnMAP L2A scenes index this plant (3 with <1% cloud cover). Source: DLR EOC STAC. Following Borger et al. (2025), these scenes can yield direct CO₂ and NO₂ plume retrievals at ~30 m spatial resolution.

Lowest cloud cover scenes (showing top 5):
