IBBAC: Impact of Biogenic Emissions on Beijing Air Quality and Climate

>> Tasks

WP1 : Biogenic emission estimates over northeastern China (BIRA, VITO, IAP)

1.1 : Derivation of a historical (1970-2010) biogenic emission record for northeastern China based on the MEGAN emission model and ECMWF meteorological fields, following Muller et al., 2008. The use of this long-term record will serve to determine a year with exceptionally hot summer, which will be considered as a reference for a “climate change” case. (BIRA)

1.2 : Improved representation in the IMAGESv2 model of biogenic and anthropogenic VOCs of importance for northeastern China, based on recent speciation data for anthropogenic VOCs and developments in the atmospheric degradation of isoprene (Stavrakou et al., 2010). An estimation of the secondary organic aerosols (SOA) formed through the oxidation of biogenic VOCs will be undertaken based on a state-of-art model for aerosol formation (Ceulemans et al., 2010).  (BIRA)

1.3 : Derivation of improved emission estimates for anthropogenic and biogenic reactive VOCs using IMAGESv2 in an inversion setup constrained by HCHO columns from the GOME-2 instrument (De Smedt et al., 2008, 2010, Stavrakou et al., 2009). Implementation of the top-down biogenic emissions in the AURORA/VITO model (BIRA, VITO).

1.4 : Generation of emissions on the AURORA grid, based on local emission inventories, and, whenever necessary, by using downscaling techniques (Maes et al. 2009), that spatially disaggregate coarse emissions to a fine grid (e.g. 1 km2). These techniques employ proxy data such as population density, positions of major roads, etc. Regarding biogenic emissions, VITO will perform downscaling of BIRA's top-down emissions, through the use of proxy data such as land cover. Updated emissions will be made available for use in the NAPQMS model of IAP. (VITO, IAP)

 

WP2 : Model/data intercomparisons  - Present and climate change model simulations (VITO, BIRA, IAP)

2.1 : Measurements of VOCs, NO2, SO2, O3 and HCHO with MAXDOAS, LP-DOAS, and Cimel sunphotometers at Beijing, Xianghe, and Xinglong stations. The past and current data series of measurements will be made available for comparisons with the AURORA/VITO and IMAGESv2/BIRA models. (IAP)

2.2 : VITO's and IAP's regional-to-urban models will use IMAGESv2 output concentration fields at the lateral boundaries, so as to account for long-range pollutant transport. IAP and VITO will closely work together in a intercomparison exercise between the AURORA/VITO (De Ridder et al., 2008) and NAPQMS/IAP model using the same high-resolution emission inventories (BIRA, VITO, IAP)

2.3 :Base case simulations will be run with AURORA for the agglomeration of Beijing at a resolution of one to a few kilometers and for a few summer seasons, as well as with the IMAGESv2 model at a coarser resolution. They will serve as a reference for evaluating the impact of biogenic emissions. Simulated concentrations will be compared to observed values provided by IAP measurements.  (IAP, VITO, BIRA)

2.4 : The reference year determined in Task 1.1 will be used as a proxy for a “climate change” case to evaluate the impact of biogenic emission changes on air quality, ozone and secondary organic aerosol formation in the Beijing region. This task can be carried out by using the AURORA/VITO model and IMAGESv2. (VITO, BIRA)
