-===== Emissions for Europe 1998-2006: 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 ([[http://www.eea.europa.eu/publications/EMEPCORINAIR5|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 ([[http://www.emep.int/grid/country_numbers.txt|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.

-===== Global Emissions 1998-2006: 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 2006, 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, RCP 8.5 scenario is taken. INERIS-EMEP emissions are regridded at a resolution of 0.5°, and merged into the global IPCC dataset.
-Data are provided in NetCDF format, where lat/lon of the cell mid-point are given.
-__** VOCs emissions estimation**__
-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 of (each VOC / totalVOCs) in IPCC emissions in 2000, is applied on total NMVOCs given by Ineris-EMEP, over Europe. \\
-Ex.: 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 the followings :\\
- * 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’)\\
