3.1 Compilation of temporal distributions (time profile for 12 months) for all sources and species
(0.15; Olivier)
As for the uncertainties, from literature review on activity data an estimate of the monthly
distribution of emissions per major source category will be made.
First a preliminary version will be developed; then a final version.
3.2 Compilation of global inventories for new compounds (0.25 my; Berdowski):
3.2.1 Version 1 of NH3 inventory (also for GEIA)
3.2.2 Other compounds or VOC compound groups
3.3 Improvement of global inventories for a number of sources (0.2 my; Berdowski)
The focus is expected to be on biofuel use and biomass burning. When readily available, also
estimates for natural emissions will be included (e.g. ocean and volcano emissions)
3.4 Limited software modification, in particular to enhance to data retrieval options (0.15 my;
Olivier)

1.1.1 Comparison with the European CORINAIR'90 inventory is scheduled for the 4 th quarter of
1996; harmonisation will be done in a separate dataset, to be merged into the next release of the
database (see 2.).
1.1.2 Comparison with national inventories for FCCC (or US Country Study Programme) will be
done when they become available. This will be limited by the extent in which the data can be
easily processed into the database. These activities will be focused at the end of 1996/first half
of 1997. The result will be an assessment report on FCCC and EDGAR inventories.
Conclusions with respect to national inventories will also aim at irregularities and improvement
of default emission factors as well as methodologies. Further work on FCCC inventories
depends on the time schedule of IPCC and the capacity made available for these activities.
1.1.3 Comparison with GEIA inventories will be done when they become available. These activities
will be focused in the first half of 1997. The result will be an assessment report on EDGAR and
GEIA inventories.

Conclusions from this exercise will be distributed among interested parties (policy makers and

participants of NRP will be consulted in the middle of 1996 and of 1997 in the form of an
informal workshop. The discussion will focus on the following topics:
- Temporal distributions, scaling, species and uncertainties;
- Integration of results of NRP 1, and of results of modelling efforts by NRP 2 tenders
(Theme I), in particular possible inputs from transportation or industry, agriculture and
natural vegetation.

This will include updating the base year of the inventories using new statistical data (aiming at
1995, possibly 1994 for industrial and agricultural sources). Data from national GHG
inventories prepared for the FCCC, concrete NRP results provided by NRP participants and
results of the validation performed under 1.1 will also be included, as well as GEIA inventories
that replace or update EDGAR work or that are not represented in EDGAR. Additional
