PUFF csenarios are named objects, selectd from a scenario selector/navigator.
The selector shows the following characteristics:
scenario name, geographic location (model domain),
owner, last modifications date.
The selector also includes a NEW button to generate a new scenario.
Editing a scenario
Once selected from the list, a summary of the scenario is shown.
This include a header with name, description, owner,
creation and last modification dates.
A primary attribute of the scenario (read only)
is the domain or location that is shown right under the header.
A second basic attribute is the start date and time. This can be modified by the
user within the constraints of data availability for the meteorological data
set pre-processed for the domain.
The PUFF scenario consists of
User options include therefore:
- A meteorological scenario or data set,
consisting of several synchronized meteorological parameter time series
generated with a meteo pre-processor; the set of synchronized meteorological parameter time series
can be visualized in a separate pop-up window.
Meteorological data sets are named OBJECTS that are derived from the
monitoring data from an applicable (nearbey) meteorological station,
the interpolation of several station, of from some meteorological model or pre-processor.
Meteorological scenarios are generated by an separate
Meteorological Scenario Generator that ensure
synchronization and consistency of the meteorological time series data.
The Meteorological Scenario Data applicable for PUFF must have a 15 minutes resolution
or time step. For internal use in PUFF, they can be interpolated to a shorter intervall.
- One or more emission sources defined by their location in the domain of the scenario;
for each emission source, a set of stack parameters (constant) and time series of emisisons
are defined, generated by an emission pre-processor.
For a user selected pollutant (constrained by the emission data availble for
the sources in the domain) for each of the emission time series, a multiplier can be defined,
setting the multiplier to 0 will switch off that source.
The set of individual source emission time series can be visualized in a separate pop-up window.
Please note that the emission data are automatically be
loaded from the emission inventory, directly from available monitoring
time serris, or generated from each source's average emission value and the temporal
- Choice of scenario;
- Choice of pollutant;
- Choice of start time; (possibly also: duration of model run);
- Scaling of the emissions (multiplicative and additive term).
Time step of the model (2 minutes) and duration (3 hours) of the episode are currently fixed.
Other data shown at the scvenario summary level include:
Defining a NEW Scenario
For a NEW scenario, the user can define:
- The domain from a pull-down menu of available domains with pre-processed DEM data;
- For each domain, one of an optional set of applicable meteorological monitoring stations;
Once a station has been selected, the default start date is the most recent date from which
a complete and consistent data set can be constructed for the duration of the episode.
