New investigations on homogeneous ice nucleation: the effects of water activity and water saturation formulations

<p>Laboratory measurements at the AIDA cloud chamber and airborne in situ observations suggest that the homogeneous freezing thresholds at low temperatures are possibly higher than expected from the so-called “Koop line”. This finding is of importance, because the ice onset relative humidity a...
