  1. EMEP/EEA guidebookupdating 4B, 4D, 4F and 6CePM from field burningConsistency check 14-16 May 2012, Bern, Switzerland Steen Gyldenkærne, Rikke Albrektsen, Mette Hjort Mikkelsen, Ole-Kenneth Nielsen Inst. for Environmental Science National Centre for Environment and Energy Aarhus University

  2. Consistency of PM in Chapter 4B • No TSP EFs • Proposal to use data for inhalable dust from reference as TSP EFs • Some errors in the calculation of EFs detected • Inconsistent animal weights compared to the NH3 model • New default animal weights proposed • Current tier 1 based on solid AWMS • Suggestion to use the average distribution for EU27 for tier 1 • Missing EFs for several animal categories • New Dutch study provides EFs for goats and fur animals • France and Switzerland reports PM emission for sheep but lacking documentation • Reasonable to assume the same EF for sheep as for goats?

  3. Updates to 4F • Consistency • Change reference for HMs to Turn et al. (Jenkins et al.) • Tier 1 EFs will be based on wheat instead of rice • Speciated PAH data available from Jenkins et al. should be implemented in the GB • Black carbon • Data for EC available from Turn et al. (Jenkins et al.) • Compared to other available data for EC and BC the data reported by Turn et al. are comparable • Proposal to use the data from Turn et al. as reference for the BC EF in the GB

  4. Black Carbon • Recommendations • To maintain the highest level of consistency between the emission factors for BC and the emission factors for the other pollutants covered, it is suggested to use the EFs reported by Turn et al. in the GB

  5. Consistency of PM in Chapter 4D • Impossible to reproduce the current EFs based on the reference • Not clear how the difference between dry and wet climatic conditions has been determined • Inconsistent information presented in the annex and main chapter in the GB • Need for input from TFEIP members who were involved in the update including PM from this sector to fix these inconsistencies

  6. Review of NMVOC in Chapter 4D • The current unit and reference for the NMVOC EF are both incorrect • Errors detected in the annex to the chapter • Values have been incorrectly used from the original reference (König et al.) • Proposal to develop tier 1 EF as average of wheat and rye EFs as reported by König et al.
