Ambient humidity is what’s happening outside your container of cannabis. It could be your bedroom, the trunk of your car, or the outdoors. In air conditioned homes, the humidity is usually 20-30% because the AC scrubs moisture out of the air. In a heated home, the humidity will often be even lower as the furnace scrubs much of the ambient humidity.

A method and system may be provided to perform a process for controlling NOx emissions of an target engine. In one embodiment of the invention, the process may include determining predicted NOx values based on a model reflecting a predetermined relationship between control parameters and NOx emissions, wherein the control parameters include ambient humidity, manifold pressure, manifold temperature, fuel rate, and engine speed associated with the engine. Further, the process may include adjusting the model based on a determination of whether the predicted NOx values meet a predetermined criteria associated with actual NOx values. The adjusted model may be stored in a memory associated with the engine whereby NOx emissions exhausted from the engine may be reduced based on virtual NOx emission values determined from the adjusted model.
