Short summary
This study presents our advanced methods to qualitatively detect ship-related nitrogen dioxide (NO2) signals in TROPOMI satellite data. By applying filtering techniques, we identify numerous global shipping routes, including previously undetected ones, as well as emissions from offshore platforms. Additionally, we compare the filtered satellite data with high-pass-filtered CAMS global model data to estimate the differences between observed and modeled NO2 emissions.
