Understanding urban to regional emissions of N2O and CH4 within the Netherlands

Understanding and reducing the emissions of N2O and CH4 are crucial for mitigating climate change. The bottom-up and top-down estimates of N2O and CH4 do not agree on multi-spatial scales and are very uncertain due to temporospatial variations in the emissions. This thesis investigates the Dutch emissions of N2O and CH4 from urban to regional scales. First, an aircraft-based AirCore system is developed and employed for high-precision atmospheric measurements of N2O and CH4 over the three urban areas of Groningen, Utrecht, and Rotterdam. The N2O emissions estimated by a mass balance approach ar... Mehr ...
