https://doi.org/10.1351/goldbook.M03936
A qualitative term applied to a @S06198@ of droplets in a gas. In the atmosphere a mist produces a generally thin, greyish veil over the landscape. It reduces visibility to a lesser extent than @F02470@ but somewhat more than haze (visibility of less than \(2\ \text{km}\) but greater than \(1\ \text{km}\)).
