Atmospheric ammonia (NH3) has great environmental implications due to its important role in ecosystem and global nitrogen cycle, as well as contribution to secondary particle formation. Here, we report long-term continuous measurements of NH3 at different locations (i.e. urban, industrial and rural) in Shanghai, China, which provide an unprecedented(More)
Observed correlations between atmospheric concentrations of CO¡ and CO represent potentially powerful information for improving CO¡ surface flux estimates through coupled CO¡-CO inverse analyses. We explore the value of these correlations in improving estimates of regional CO¡ fluxes in East Asia by using aircraft observations of CO¡ and CO from the TRACE-P(More)
