Megacity and local contributions to regional air pollution: an aircraft case study over London

Kirsti Ashworth et al.

Data sets

Airborne atmospheric measurements from core and non-core instruments on board the BAE-146 aircraft Centre for Environmental Data Analysis, CEDA https://catalogue.ceda.ac.uk/uuid/09d7fd5586bd446aab8947274b15168f

Short summary

In July 2017 we flew three research flights around London during European Facility for Airborne Research (EUFAR) training. We made continuous measurements of concentrations of key pollutants (ozone, NO_x, aerosol particles, CO, CO₂ and methane) and meteorology, and we collected periodic samples of air to analyse for volatile organic compounds. We saw evidence that plumes of pollution from the city, strong local emissions and pollution from distant sources all contribute to regional pollution.
