Building a quantitative correspondence between pollution levels and its causes requires the use of a modeling exercise.

DSS calculates the contribution by feeding a model with data on different sources of pollution, such as the number of fires recorded in Punjab and Haryana, the air quality in Delhi's neighboring districts, and other satellite-based indicators of pollution (and as we learnt on Tuesday, DSS also uses some off-the-wall measures, such as the number of weddings in Delhi, and assuming that fireworks will be used in each).
