Findings from the EU-funded ALP-AIR project indicate that current assessments of nitrogen oxide pollution from traffic are underestimated, by up to a factor of four.
Researchers from the EU-funded ALP-AIR project recently published findings from their continuous monitoring of trace gases concentrations in air. The team used the atmospheric measurement method called ‘eddy-covariance’ which applies statistical analyses to source data, inferring emissions within a radius of about one kilometre of the measurement location.
