into the final model output. The information of fine scale emissions is treated in
a statistical manner as the fraction of the grid-averaged emission that is due to
source-specific emissions. In this manner we do not need to locate exactly the
emission sources, either to explicitly account for dynamical processes such as
eddies in street-canyon structures.
Bernard Fisher:
Do you have human activity data for Paris in order to do the
exposure assessment, which depends on the amount of time people spend in the
different micro-environments?
Answer:
There does not exit a human-activity patterns data base for Paris
population at the moment. A simple data-base was created for the purpose of
this study, based on demographic data over the region of Paris. Then we coded
a Monte-Carlo algorithm that mapped the members of the population over the
study domain at the resolution of the CTM, respecting the distribution of the
initial demographic data.
