How official national inventory data is used as

How official national inventory data is used as input data for EMEP models Katarina Mareckova, Robert Wankmueller CEIP - Centre on Emission Inventories and Projections GMES workshop 10 -11 Oct 2011

CEIP – Centre on Emission Inventories and Projections n CEIP is hosted by the Umweltbundesamt Gmb. H in Vienna since January 2008 (http: //www. ceip. at) n The main tasks are: ¨ ¨ ¨ Collection of emissions and projections of acidifying air pollutants, heavy metals, particulate matter and photochemical oxidants from Parties to the LRTAP Convention. Review of submitted data Assistance of Parties in improving the quality of national inventories Publication of emission inventories Support to the UNECE/CLRTAP secretariat Expert adjustments and preparation of submitted emission data for long-range transport models ( gap filling and gridding)

Review of submitted data n Automated checks of format, completeness and consistency of trends before data is imported to the CEIP DB (Rep. Dab check) n Immediate / Direct feedback to Parties

Review of inventories under CLRTAP n Methods and procedures for the technical review of air pollutant emission inventories reported under the Convention and its protocols (EB. AIR/GE. 1/2007/16) ¨ ¨ Stage 2 – Synthesis and assessment tests, country data is published annually (31 May) on the CEIP website ¨ n Stage 1 – automated tests, country reports are published annually (during March) on the CEIP website Stage 3 – Centralised in-depth review, 10 Parties are reviewed each year A summary of the S 1 and S 2 findings is published in the annual Inventory Review Reports http: //www. ceip. at/review-process/review-2011

Procedure for expert adjustments 1. 2. 3. Extraction of latest year data and data from previous years from the CEIP database (NFR) Conversion of 117 NFR categories to 11 SNAP sectors Import of converted values to Excel spreadsheets – together with „Expert Data“ from previous years – for the gap-filling procedure

11 SNAP sectors n n n S 1 - Combustion in energy and transformation industries S 2 - Non-industrial combustion plants S 3 - Combustion in manufacturing industry S 4 - Production processes S 5 - Extraction and distribution of fossil fuels and geothermal energy S 6 - Solvent use and other product use S 7 - Road transport S 8 - Other mobile sources and machinery S 9 - Waste treatment and disposal S 10 – Agriculture S 11 - Other sources and sinks NFR to SNAP mapping table: http: //www. ceip. at/fileadmin/inhalte/emep/pdf/NFR 09_SNAP_GNFR. pdf

Methods used for gap-filling n Use of other officialy available data (NECD, UNFCCC, IIASA, MSC-W, MSC-E, ENTEC, …) n Linear extrapolation of officially submitted data or expert data n Copy of expert data from the previous year n Shipping emissions IIASA/ENTEC estimates Import of gap-filled data to the CEIP database

Gridding process Gridded data from official submissions and other data sources Grid Scaler Base grid for each component Gap-filled SNAP values (expert data) CEIP Database Sector Scaler Grid files for each component

Grid Scaler Population distribution data Gridded sectoral data reported by Parties Gridded national totals reported by Parties Grid. Scaler (Generate base grids for each component) Data sources Gridded sectoral data from TNO (emission data derived from satellite images) Large point source data reported by Parties and the „Genemis Project“

Grid Scaler – Scaling order Official gridded sector data Combination of population data and reported LPS data (The partitioning is defined by POP_LPS_TNO_RATIO) Combination of Population and LPS data from the „Genemis Project“ (The partitioning is defined by POP_LPS_TNO_RATIO) Gridded sectoral data from TNO Only Population data

Grid Scaler – POP_LPS_TNO_RATIO Sector 1 Sector 2 Sector 3 Sector 4 Sector 5 Sector 6 Sector 7 only LPS data only Population data 50% Population data / 50% LPS data only gridded sectoral data from TNO only Population data NOx distribution from official gridded sectoral data OR gridded sectoral data from TNO Sector 8 like Sector 7 Sector 9 is defined by the „S 9_GRID_COUNTRY_RATIO“ (see next slide) Sector 10 NH 3 distribution from official gridded national total data OR gridded sectoral data from TNO

Grid Scaler – S 9_GRID_COUNTRY_RATIO n Different weightings of population-, LPS- and TNO- data for each country, whereas ¨ The TNO value defines the percentage of agriculture related waste ¨ The population value defines the percentage of urban population related waste ¨ The LPS value defines the percentage of flaring/oil related waste

Grid Scaler – S 9_GRID_COUNTRY_RATIO Definition for each country: Column 1: Country Column 2: TNO data weighting Column 3: Population data weighting Column 4: LPS data weighting

Grid Scaler – Result (Base grid) n The result is a base grid for each component (standardised to 109 per sector and country)

Sector Scaler n Allocate the emission values from the gap-filling process regarding the base grids n The result are grid files for each component

Procedure for updating the EMEP database 1. 2. 3. 4. Checking of gridded data by MSC-W Performing necessary updates Upload of gridded data to the CEIP database Activation for experts and public access via the CEIP homepage http: //www. ceip. at/emission-data-webdab/emissions-as-used-in-emep-models/

Update of historical gridded emissions Differences between previous year‘s gridded and this year‘s re-gridded emissions for the year 2000

Reporting of emission data to EMEP Reporting of gridded sectoral data

Upcoming changes to the EMEP grid Katarina Mareckova, Robert Wankmueller CEIP - Centre on Emission Inventories and Projections GMES workshop 10 -11 Oct 2011

Present gridding system n Polar stereographic projection n Grid resolution: 50 x 50 km² n 10 SNAP sectors + National Total n Pollutants n MAIN: NOx, NMVOC, SOx, NH 3, CO) (since 2008 by CEIP, before MSC-W) n PM (PM 2. 5, PMcoarse) (since 2008 by CEIP, before MSC-W) n HM (Pb, Cd, Hg) (since 2009 by CEIP, before MSC-E) n POPs (PCDD/PCDF, HCB, Ba. P) (since 2010 by CEIP, before MSC-E)

Discussed further modifications to the EMEP grid n Change of the grid projection from the current polar-stereographic (PS) grid to geographical coordinates (latitude-longitude grid) n Increase of the grid resolution (0. 1° x 0. 1° or even less) n Optional: Reduce only grid size and keep PS projection (10 x 10 km² or 5 x 5 km²) n Gridding in GNFR sectors (introduced in 2009 with the new NFR reporting templates) instead of 10 SNAP sectors

Next steps in the development of a new EMEP grid n Revision of the Reporting Guidelines n Decision of the EB on future reporting of gridded data n Definition of the requirements to a new gridding system (What is essential and what is nice to have) n Timeframe for the development n Grid definition for sea areas and the extended domain (Where should be the new grid domain borders? ) n Agreement on GNFR sectors used for gridding

Next steps in the development of a new EMEP grid n Definition of new „proxy base grids“ (Derived from digitised maps, e. g. road network, shipping routes, airports, etc. ) n Definition of new „base grids“ for the emission distribution of each pollutant and sector Derived from „proxy base grids“ and other spatial data (e. g. LPS data) n Transition phase between „old“ and „new“ EMEP grid (data comparability, data migration, re-gridding, etc. ) n Gridding procedure until the new system is available (Convert reported GNFR grids to SNAP sectors) n Specification and implementation of a new gridding software
