- dew point: the point at which water vapor condenses into droplets of water
- haze: dry dust particles in the air
- radiation fog: a cloud of water droplets formed when the cooling ground lowers the temperature of the air above it to its condensation point
- relative humidity: the ratio of the current amount of vapor in the air to how much vapor the air can hold at saturation
