Understanding emissions where urbanisation is happening
This exciting new projected started in 2015 and is a collaboration of the LSCE and CPRH, the air quality agency of Pernambuco, Brazil. The city of Recife has been active to better understand their Greenhouse Gas emissions and this project has been established to bring together international and local scientists and engineers to facilitate this. Quantifying emissions from a large urban area (ca. 3.7 Mio inhabitants) in South America is both scientifically interesting as well as policy relevant.
We have successfully installed two continuous measurements stations and can clearly follow the daily variations of carbon dioxide, methane and carbon monoxide concentrations in Recife. To derive emission estimates from these measurements we have built an inversion framework. Firstly we had to develop an spatialised emission inventory i.e. a map of the emission in Recife, which was much harder than in many other cities as less data was available - but it worked. Now we have just finished the modelling of atmospheric CO2 concentrations and we can start to investigate the difference between the measured and model predicted CO2 concentrations in Recife... more to come...
