State-of-the-art contrails detection in MTI magazine

Aviation's environmental footprint extends beyond just CO2. Non-CO2 effects like nitrogen oxide emissions and contrails also significantly influence climate change. Although contrails may seem minor, their cumulative warming effect could notably contribute to global warming by 2050. Understanding and mitigating this impact is essential for a more sustainable aviation future. Collaborative Efforts to Reduce Contrail Impact Several airlines are testing flight rerouting strategies to
