1. A method for an engine, comprising:
adjusting engine operation based on an ambient specific humidity estimated based on a dry bulb temperature measured by a first sensor positioned on an exterior surface of a vehicle and shielded from weather, a wet bulb temperature measured by a second sensor positioned on the exterior surface of the vehicle and exposed to weather, and a barometric pressure in response to detecting precipitation. |
