The HTAP_v3 mosaic has been developed in the context of the UNECE Air Convention (UNECE Convention on Long-range Transboundary Air Pollution, link: https://unece.org/page404/env-lrtap) as a community effort to improve the scientific knowledge of the intercontinental transport of air pollution over the Northern Hemisphere (http://htap.org/). It consists of a global mosaic of monthly air pollutant (SO2, NOx, CO, NMVOCs, NH3, PM10, PM2.5, BC, OC) emission gridmaps at 0.1x0.1 degree resolution covering the time series 2000-2018 and all anthropogenic emission sectors, with the exception of Land Use, Land Use Change and Forestry. Emission gridmaps have been collected from officially reported data, and specifically from EMEP for Europe (CAMS-REG-v5.1), from the US Environmental Protection Agency (US EPA), Environment and Climate Change Canada (ECCC), REAS for most of the Asian domain, from Japan and CAPPS-KU for Korea. All remaining countries in the world have been covered using EDGARv6.1 air pollutant emission gridmaps. Furthermore, the EDGAR data have been used to complement the officially reported data as gapfilling source in case of missing data for certain sectors, pollutants and years.
Compared to the previous HTAP mosaics (HTAPv1, HTAPv2.2), HTAP_v3 aims at extending the temporal coverage of the air pollutant emissions, their sectoral breakdown and the geographical coverage of the official data. The overall purpose is to provide the scientific inventory and modelling communities a comprehensive tool to develop trend analysis, study the transboundary transport of air pollutants, and help policy makers in addressing and mitigating emissions for relevant sectors.
HTAP_v3 covers the following emission sectors:
|HTAP_v3 main sectors||HTAP_v3 detailed sectors|
|HTAP_1: International Shipping||HTAP_1: International Shipping|
|HTAP_2: Aviation||HTAP_2.1: Domestic Aviation|
|HTAP_2.2: International Aviation|
|HTAP_3: Energy||HTAP_3: Energy|
|HTAP_4: Industry||HTAP_4.1: Industry|
|HTAP_5: Ground Transport||HTAP_5.1: Road Transport|
|HTAP_5.2: Brake and Tyre wear|
|HTAP_5.3: Domestic shipping|
|HTAP_5.4: Other ground transport|
|HTAP_6: Residential||HTAP_6: Residential|
|HTAP_7: Waste||HTAP_7: Waste|
|HTAP_8: Agriculture||HTAP_8.1: Agricultural waste burning|
Annual and monthly time series (2000-2018)
Time series (2000-2018) of monthly and annual emissions by sector and country as .xls files.
Notes: Monthly (or Annual) emissions by country and sector are expressed in Mg/month (or Mg/year).
Annual and monthly gridmaps (2000-2018)
- Monthly emission (in Mg/month) gridmaps at 0.1x0.1degree resolution: one .NetCDF file per year and substance is produce including for each sector the emissions for the 12 months.
- Monthly gridmaps of emission fluxes (in kg/m2/s) at 0.1x0.1degree resolution: one .NetCDF file per year and substance is produce including for each sector the emission fluxes for the 12 months.
- Annual emission (in Mg/year) gridmaps at 0.1x0.1degree resolution: one .NetCDF file per year and substance is produce including the emissions for each sector.
- Annual emission (in kg/m2/s) gridmaps at 0.1x0.1degree resolution: one .NetCDF file per year and substance is produce including the emission fluxes for each sector.
