inventories. This means the underlying activity data tables need to be “translated” and linked in the various databases.
For the purpose of the MEGAPOLI questions detailed, high quality and high resolution city inventories need to be
available both as model input and a base for mitigation measures. For each selected megacity a partner will adopt the

Task 1.5: European heat flux inventory (lead: KCL, TNO)
To assess the impact of Mega cities on local climate the heat flux is important. Heat may be produced at a different
location than the fuel is combusted (e.g. electricity generation and consumption). This tasks aims at making a European
anthropogenic heat flux inventory by using the activity data and spatial distribution of task 2 and working with heat flux
factors developed in cooperation and linked to WP2.
Task 1.6: Validation, evaluation and improvement of EI’s (all WP partners)
Task 1 and task 2 will start out with delivering a first working version of the desired inventories in the first year of the
project. After delivery further improvement of the EI’s will be pursued through; 1) feed back from modellers working
with the EI’s; 2) A general review of regional source apportionment studies to improve EI’s at the regional scale; 3)
Validation through measurement data and source apportionment within MEGAPOLI (WP3 and WP4).
Task 1.7: Processing of emission inventories for model sensitivity and scenario runs (lead: TNO, MPIC)
Several sensitivity runs will be carried out in WP5 and scenario runs in WP6 and WP8. Emissions for these runs will be
processed here. In particular, for WP5, two types of sensitivity runs will be used to characterize the impact of
megacities. In the first, the net effect is determined by simply removing the total emissions from the grid cells
comprising each megacity. This will be done first in the high-resolution emission data (particularly the 0.1 degree data,
which should be made available by EDGAR in early 2008), then interpolated to the coarser model grid, to best simulate
the change due to the megacities. The second type of sensitivity run will redistribute the emissions by assuming that a
fraction of the population (e.g., 10%) of each megacity under consideration were to move to the surrounding regions,
thus decreasing the megacity emissions and increasing the rural emissions accordingly. We will explore different
approaches to doing this, such as spreading the relocated population evenly throughout the country, or only in the
suburban or rural regions immediately surrounding the megacity. Furthermore, for WP5, WP6, and WP8 future
scenario datasets will be developed, including sensitivity run datasets based on the same approach as described above.
for the sensitivity run datasets Further scenarios, particularly for WP8 may also be requested as the project progresses.
