Tan et al. studied an interesting phenomenon – supersaturation, i.e., water vapor pressure exceeding saturation value – in the atmosphere by assembling data from multiple aircraft measurement campaigns. We find the climatic impact, as measured by radiative forcing, of supersaturation is significant and, interestingly, very sensitive to co-existing clouds. Particularly, we note an interesting change of the sign of the radiative effect of cirrus cloud at optical depth ~ 1.8 (see Manuscript Fig. 3j and Supplementary Information Fig. S4). Read more about it in this article “An assessment of the radiative effect of supersaturation based on in-situ observations“.
