inventories for new compounds or natural sources may be added as they are available for<br />

external distribution. Together with new releases, concise documentation files on will be<br />

prepared.<br />

5HFRPPHQGDWLRQVWRSROLF\PDNHUV. Evaluation of key sources/regions of updated inventories<br />

in V3.0 are scheduled for September 1996 and for the beginning of 1998. Ad hoc advice to<br />

policy makers may be given at any time during the project.<br />

model will be included in the time schedule of updates of IMAGE 2; (3) updated versions of<br />

emissions data will be made available as standardised emissions data files at <strong>RIVM</strong>'s<br />

Version 1 of an NH3 inventory (also for GEIA) is scheduled to be ready by October 1996. For<br />

which is scheduled for February 1998.<br />

Data on biofuel use and biomass burning will be improved in co-operation with GEIA groups<br />

working on these topics and incorporated in V3.0. On these sources a summary <strong>report</strong> will be<br />

written. When they become available, also estimates for natural emissions will be included in<br />

the database and made available through the FTP site.<br />

/LPLWHG VRIWZDUH PRGLILFDWLRQ will focus in 1996 on enhancing data retrieval and dataset<br />

comparison options.
