Emissions for CityZen

Last updated: August 18, 2010

Emissions for Europe 1998-2007: Description

Emissions for Europe have been provided by Bertrand Bessagnet (INERIS) and Guillaume Siour (LISA/INERIS/ADEME) for different years. The emissions are given on a lon/lat coordinate system. The emission inventory has been directly elaborated from the 0.5°x0.5° EMEP emissions available at http://www.emep.int

Emissions within each 0.5°x0.5° EMEP grid cell are regridded to a 0.1°x0.1° lon/lat grid using a fine scale global land cover database at a about 300 m resolution called GlobCover. More information about GlobCover can be found at http://ionia1.esrin.esa.int/

'Crops' and 'grass' land covers are used to reallocate agricultural emissions

'Articial areas' land cover is used to reallocate the other anthropogenic sectors

Maritime emissions (sector 8) are processed separately

One file per pollutant and per year was generated. Within each file, emissions are given as an annual total per grid cell and per SNAP sector (information about SNAP). Emission units are Mg/cell. NOx are given in equivalent NO2.

All files are organized as follows:

1st column	Country/Area code (EMEP codes)
2nd column	Latitude (mid-point)
3rd column	Longitude (mid-point)
4th column	Emission Sector 1
...	...
14th column	Emission Sector 11

Caution: the codes for maritime zones can have 2 or 3 digits. Choose either 2 or 3 digits for these codes, do not sum all. In doing so, you would double-count the emissions!

Sector 11: Only SOx emissions have non-zero values. Particulate matter: 1998 and 1999 PM annual totals are the same.

The creators of the data set also acknowledge Jean-Louis Monge and Marc Stefanon (INERIS) for helping with the regridding procedure.

Note 28JAN2010:

Some emissions files were amended in January 2010 to account for an inconsistency in the way PM emissions were reported:

There are no PM (2.5 and coarse) emissions in North Africa (country code 63) before 2007. These emissions start in 2007. This is an issue for the reconstruction of a trend so we decided to switch off PM emissions in North Africa in 2007

There are no PM (2.5 and coarse) emissions over the sea areas (country code 30, 31, 32, 33, 34 for this year) in 1999. We thus decided to copy over-sea PM emissions from year 2000 to 1999

There are no PM (2.5 and coarse) emissions in 1998. We thus decided to copy PM emissions from year 1999 to 1998. This is the same as for the previous version of the emissions, except that 1999 PM emissions have changed

Global Emissions 1998-2005: Description

Global anthropogenic emissions have been provided by Aude Mieville and Claire Granier (CNRS/LATMOS) for CO, NOx (as NO), total NMVOCs, SO2, NH3, BC, OC and 13 VOCs. They are provided from 1998 to 2005 at a 0.5°x0.5° resolution.

Emissions are constructed from two datasets: a new global historical inventory in decadal increments developped for use in the next IPCC AR5 simulations (called IPCC hereafter), and the INERIS-EMEP inventory for Europe at 0.1° resolution.
Global emissions are derived on an annual basis by interpolating the IPCC emissions in 1990, 2000, 2005, and 2010. For years 2005 and 2010, the RCP 8.5 scenario is taken. INERIS-EMEP emissions are regridded at a resolution of 0.5°, and merged into the global IPCC dataset.

FORMAT: Data are provided in netCDF format, where lat/lon of the cell mid-point are given.
VOC emissions estimation

The INERIS-EMEP inventory only provides total NMVOCs emissions. The speciated VOCs emissions are estimated from 2000 IPCC emissions of VOCs and total NMVOCs. The sectors spatial distribution is assumed to be the same, and the gridded ratio VOC/totalVOC in the IPCC emissions in 2000 is applied on the total NMVOCs of INERIS-EMEP over Europe.

Example: For each year, and each grid point (i,j), emissions for C2H4 are derived as:
Em_C2H4(i,j) = Em_totNMVOCs(i,j) *
( Em_IPCC2000_C2H4(i,j) / Em_IPCC2000_totNMVOCs(i,j) )
The VOCs provided are:
* C2H4, C2H6, C3H6, C3H8
* Butane and higher alkanes (as ‘BIGALK’)
* Butene and higher alcenes (as ‘BIGENE’)
* CH3OH
* C2H5OH + higher alcohols (as ‘C2H5OH’)
* CH2O
* CH3CHO + higher aldehydes (as ‘CH3CHO’)
* Acetone (as ‘CH3COCH3’)
* Other ketones (as ‘MEK’)
* Aromatics (as ‘TOLUENE’)

Emission ratios for selected CityZen regions 2030: Description

Emission rations have been provided by IIASA for year 2030 in an EXCEL table, based on five scenarios:

1) 2030 UNEP_IEA09_REF
2) 2030 UNEP_IEA09_REF lowGWP
3) 2030 UNEP_IEA09_REF MFR
4) 2030 UNEP_IEA09_450
5) 2030 UNEP_IEA09_450 lowGWP

The scenarios refer to the IEA world energy outlook 2009 activity projections as they are implemented into GAINS. 'REF' is the baseline pathway and '450' is the 450 ppm CO2-eq stabilization scenario.

These are further devided into subscenarios with different measures implemented. The lowGWP introduces a set of measures that reduce efficiently the net Global Warming Potential. MFR is the maximum feasible reduction potential.

For five main pollutants and 11 SNAP sectors, the Excel table gives ratios in the four selected regions in CityZen, and globally.

Example 1:
In order to obtain SO2 emissions in SNAP 8 in the Po Valley in 2030 according to the baseline scenario UNEP_IEA09_REF, you have to multiply your 2005 emissions for SO2 by 0.236 (see grid cell C50 on SO2 sheet).

Example 2:
In order to obtain NOx emissions in SNAP 3 in BeNeLux in 2030 according to the 'UNEP_IEA09_450 lowGWP' scenario, you have to multiply your 2005 emissions for NOx by 0.755*0.960 (see C6 and I6 on NOx sheet).
