Shipping emissions
Shipping emissions monitoring screens vessel-related NOx, SOx, and particulate pollution through atmospheric column enhancements, plume patterns, and correlation with maritime activity.[1][2][3]
Sentinel-5P TROPOMI measures atmospheric trace gases including NO2 and SO2 in UV-visible and SWIR bands and supports shipping air-pollution screening.[1]
Shipping-lane NO2 signals can be extracted from TROPOMI data, but robust detection usually relies on filtering, aggregation, and correlation with route patterns rather than single-pixel attribution.[2][3]
Individual-vessel emission attribution is harder than lane or port screening because wind, plume dispersion, background pollution, and revisit timing confound the signal.[2][3]
