Emissions sensitivity tool Emissions sensitivity tool motivationmotivation

Provide an ‘easy-to-use’ entry into the EMF Provide an ‘easy-to-use’ entry into the EMF Allow modelers to set up and run Allow modelers to set up and run

emissions sensitivities based on SMOKE emissions sensitivities based on SMOKE Cases previously run by the emissions Cases previously run by the emissions modelersmodelers

Modelers will not need to be intimately Modelers will not need to be intimately familiar with all the details needed to set familiar with all the details needed to set up the original cases up the original cases
