The product uncertainty mainly comes from the limited coverage of the measurement network and from errors in atmospheric transport modelling. (climate.copernicus.eu)
And because the comb measurements can be averaged over the entire path length rather than relying on a few spot measurements, the comb method is better matched to the scale of atmospheric transport models. (sciencedaily.com)
Here we assess the capability of ground - based observations and a high - resolution (1.3 km) mesoscale atmospheric transport model to determine a change in greenhouse gas emissions over time from a metropolitan region. (aer.com)
