Time profiles are distributions to describe the monthly, daily, and sometimes also weekly variation in<br />
annual emissions to account for seasonality and diurnal variation as well as the weekly rhythm of<br />
working and recreational hours. These are often required for atmospheric modellers as input into their<br />
models. In general, likewise increasing spatial resolution from global to regional to country to grid<br />
emissions, increasing temporal resolution from annual emissions to monthly to weekly to daily<br />
variation also increases the uncertainty in the estimates. Here the distinction can be made between<br />
FKDUDFWHULVWLF temporal variation which is a kind of ‘multi-year average’ and temporal variation in a<br />
specific time interval, so-called HSLVRGLF variation. From comments by the atmospheric modelling<br />
community it appears that for global modelling, at which the global inventories specifically aim,<br />
seasonality is the most important time aspect to consider. It depends on the type of model whether<br />
they need characteristic of episodic time profiles. It should be stressed, however, that anthropogenic<br />
emissions show much less temporal variation compared to natural emissions which are often strongly<br />
dependent on weather factors. In Table 4.13 the priority setting for compiling time profiles is<br />
summarised per source category in relation with their contribution to total emissions of specific<br />
compounds.<br />
