Comparing a scenario
Every demo carries several scenarios: the base case and one or more alternative plans — a fuel switch, a declared environmental episode, an emergency. Quintero’s, and the reasons for them, are in this demo. A scenario is not a second demo: it is the same domain, the same receptors and the same weather, with different emissions.
Switching scenario
Section titled “Switching scenario”The SCENARIO selector is in the top bar. Changing it moves everything at once — the concentration layer, the receptor values, the timebar shading, the Alerts and Receptors panels — and nothing else changes: not the instant, not the species, not the camera. The difference you see is, by construction, the difference between plans.
The quickest comparison is to leave the map on an instant and a receptor that matter, and toggle the selector. The second is the Receptors panel with the Scenario pivot: every receptor, every scenario, in one table coloured by level.
Who causes what: the source group
Section titled “Who causes what: the source group”Beside the scenario sits SOURCE GROUP. With Total, the map and the receptors show the sum of all sources; with a group chosen, they show only that group’s contribution. It is how to see where what a receptor receives comes from.
Two rules keep that reading honest. Alerts are always evaluated on the total — a group alone does not cross thresholds, the sum does — and the Series panel shows the total even with a group chosen. And in the Receptors panel, the Group pivot puts the contributions side by side with the Total column, where each group’s share reads at a glance.
On the dashboard
Section titled “On the dashboard”The dashboard’s Scenarios section gathers the same in writing: an overview, Impact — what each scenario did at the receptors, ordered by severity — and Comparison, scenario against scenario.
